Electrical Panel Upgrade Please tell me: - Will you perform a formal load calculation (Manual J for HVAC, Article 220 for electrical)? - Are you familiar with San Jose permits and any local rebate programs? - Can you give line-item pricing and separate confirmed incentives from assumed incentives? - Who handles permits, inspections, and rebate paperwork?
Technical basics in plain English
Panel size: 100A, 125A, 150A, 200A
Your electrical panel is the main entry point for electricity into your house. The 'A' means amps. More amps means more total electrical capacity. 100A is older and may not support adding heat pump + water heater + EV charger together without an upgrade or smart load management. 125A/150A is middle ground; could work with efficient equipment and a real load calculation. 200A is usually the cleanest path, but not guaranteed.
Ask: What is my panel size, and can you show me the load calculation that proves this setup is safe?
Load calculation
A load calculation is not the same as guessing. It is a code-based calculation that estimates whether your panel and service can safely carry all major electrical loads. A qualified electrician or contractor should be able to explain whether you need a panel upgrade, a service upgrade, or smart load management instead.
Ask: Are you doing a formal electrical load calculation, or just eyeballing the panel?
120V vs 240V
Normal outlets are usually 120V. Large appliances often use 240V, like a dryer or EV charger. Many heat pump HVAC systems, EV chargers, and some water heaters need 240V.
Ask: Which parts of this project require 240V?
Smart load management
Smart load management lets devices avoid running at full power at the same time. For example, the EV charger may slow down while the heat pump or water heater is running. This can sometimes avoid an expensive panel or service upgrade.
Ask: Can smart load management avoid a service upgrade while still supporting future loads?
Manual J load calculation (HVAC)
Manual J is the standard HVAC sizing calculation. It accounts for home size, insulation, windows, orientation, and ductwork. A good HVAC contractor performs Manual J before sizing the equipment; bad contractors just match the existing furnace tonnage.
Ask: Will you perform a Manual J load calculation before sizing the equipment?
Battery backup: whole-home vs essential-loads
Whole-home backup tries to power almost everything during an outage. Essential-loads backup powers selected circuits (refrigerator, internet, lights, some outlets). Whole-home backup costs more and drains batteries faster. Essential-loads backup is usually more economical.
Ask: Are you quoting whole-home backup or essential-loads backup? Which specific circuits will be backed up?
Specific questions to ask
Questions for HVAC contractors
| Question | Good response | Bad response |
|---|---|---|
| Will you perform a Manual J load calculation before sizing the heat pump? | Yes. We calculate heating and cooling load based on home size, insulation, windows, orientation, ductwork, and infiltration. | We just replace the existing furnace with the same tonnage system. |
| Will you inspect ducts before specifying the heat pump? | Yes. We inspect duct size, leakage rate, return air paths, and airflow because heat pumps need good airflow at moderate static pressure. | Ducts are always fine; no need to check. |
| How do you decide system size in tons or BTU? | We explain tons and BTU using Manual J inputs, not just square footage. | We use 1 ton per 500 square feet as a rule of thumb. |
| Will the heat pump cover both heating and cooling, and do we need backup heat? | Yes, a central heat pump provides both. We explain whether backup electric resistance heat is recommended for San Jose's mild winters. | Cooling is a separate system. |
| What refrigerant does the system use, and is it compliant with current EPA rules? | We specify the refrigerant (R-454B or R-32 for new systems after the EPA A2L transition) and confirm it meets current code. | Refrigerant does not affect homeowners. |
| What is the outdoor unit noise rating, and where will it be located? | We provide the published decibel rating, propose an installation location that meets San Jose's noise ordinance, and account for setback to property lines. | Heat pumps are quiet enough to put anywhere. |
| How will the heat pump perform during the coldest week of the year in San Jose? | We use the published HSPF2 or COP at the local design temperature (~41F for San Jose, the ASHRAE 99 percent heating design temperature), and confirm the system maintains capacity without significant backup heat usage during typical cold spells. | Heat pumps work fine in California. |
| Are you familiar with San Jose Clean Energy (SJCE) EcoHome rebates and how to coordinate them? | Yes, we may help homeowners apply for SJCE EcoHome rebates and confirm program availability before installation. | All rebates are guaranteed; we will get them for you. |
| Are you a TECH Clean California enrolled contractor, and is the program currently funded for heat pump HVAC? | We verify current TECH Clean California program status (single-family Phase I has been fully reserved since November 2025) and explain whether it applies before signing. | TECH always pays out; assume the rebate is yours. |
| Does my household income make us eligible for HEEHRA, and what does that involve? | We confirm income eligibility (below 80 percent AMI or 80 to 150 percent AMI), explain pre-approval is required, and verify program status (Phase I single-family is currently fully reserved per CEC as of 2026-02-24). | HEEHRA covers everyone; you qualify automatically. |
Questions for water-heater contractors
| Question | Good response | Bad response |
|---|---|---|
| Where will the heat pump water heater go, and does the location have adequate air volume? | We assess garage and utility room candidates (heat pump water heaters need roughly 700 to 1000 cubic feet of conditioned air around the unit, or a ducted exhaust path), evaluate noise impact, and confirm clearance per the manufacturer's install manual. | Any closet works for a heat pump water heater. |
| How will you handle the condensate drain? | We route a gravity drain to an approved disposal location or use a condensate pump; we explain freeze risk and overflow safety per CPC, and itemize the work in the quote. | Condensate isn't really an issue. |
| How will you size the tank, 50, 65, or 80 gallons? | We size from household occupancy, peak-hour fixture demand (showers, dishwasher, clothes washer simultaneity), and recovery preferences. A typical 3-to-4-person household lands on a 65 or 80 gallon unit to compensate for slower heat pump recovery vs gas. | Match the gallons of whatever tank is there now. |
| What is the first-hour rating of the proposed unit, and is it sufficient for our peak demand? | We provide the manufacturer's first-hour rating (gallons delivered in the first hour of peak use) and compare it to your typical morning or evening peak demand. We may suggest a larger tank or a mixing valve strategy when the rating runs tight. | First-hour rating isn't really relevant. |
| What is the Uniform Energy Factor (UEF) of the proposed unit, and how does it affect rebate eligibility? | We document the UEF on the spec sheet (modern heat pump water heaters typically range 3.0 to 4.0+ UEF). Many rebates require UEF at or above a threshold (often 3.0) or a NEEA Advanced Water Heater Specification tier rating; we confirm the eligible tier before submitting. | UEF doesn't matter for rebates. |
| Will the install be ambient (drawing from the room) or ducted? | Ambient installs are simplest and cheapest in a garage or large utility room. Conditioned-space installs may need ducted intake or exhaust to avoid cooling the living space; ducting adds labor and material cost. We model the tradeoff in the quote. | Ducting is always required. |
| What operating modes does the unit support, and which one do you recommend by default? | Most modern units offer heat-pump-only (most efficient), hybrid (heat pump plus resistance backup on high demand), and resistance-only (emergency or cold-snap) modes. We recommend hybrid as a default and explain how mode choice changes runtime and operating cost. | Modes are a gimmick; leave it on resistance. |
| What is the manufacturer warranty on the tank, the heat pump compressor, and labor? | Most residential heat pump water heaters carry a 10-year tank warranty and a separate compressor warranty (often shorter). We provide the spec sheet and itemize our labor warranty separately so they aren't confused. | Lifetime warranty; no fine print. |
| If we are switching from gas, how will you decommission the gas line? | We cap and label the abandoned gas line per CPC, pressure-test or visually verify the cap, and remove the abandoned T&P discharge pipe if it conflicts with the new install. The work is itemized in the quote. | Just leave the old gas line where it is. |
| What is your post-install commissioning checklist? | Commissioning includes pressure testing the plumbing, verifying the T&P relief valve and discharge routing, confirming the condensate drain runs free, setting the default operating mode, and walking through the app and any user controls. | We turn it on and leave. |
| What is the expected recovery time after a high-demand event, like back-to-back showers? | In heat-pump-only mode, recovery is slower than gas (typically 2 to 3 hours to reheat a depleted tank). Hybrid mode shortens that. We explain mode tradeoffs and may recommend a larger tank or a mixing valve strategy when recovery is a concern. | Recovery is the same as gas; no tradeoff. |
Questions for solar + battery installers
| Question | Good response | Bad response |
|---|---|---|
| How will you size the solar array for our future electric load (heat pump HVAC, EV, water heater)? | We model expected future usage including planned heat pump, EV miles, and water heater, then size the array to offset that load under NEM 3.0 export economics. | We size the system from last year's utility bill only. |
| How does NEM 3.0 change the economics versus older interconnections? | NEM 3.0 cut export compensation by ~75 percent versus NEM 2.0, which makes battery storage important for self-consumption. We model expected savings under NEM 3.0 specifically. | NEM 3.0 is the same as NEM 2.0 economically. |
| Is my roof suitable for solar, and what is its remaining lifetime? | We inspect the roof condition, slope, orientation, and shade pattern; we recommend roof replacement first if the roof is near end of life. | Any roof works. |
| Which panel and inverter brands do you recommend, and why? | We name the specific panel model (wattage, efficiency, temperature coefficient, degradation curve) and inverter brand (string vs microinverter), explain the tradeoffs for our roof, and provide the manufacturer datasheets. | We use whatever is cheapest in stock this month. |
| Will the array use string inverters, microinverters, or DC optimizers, and why? | We choose based on roof shading patterns and orientation: microinverters or optimizers for shaded or multi-orientation roofs, string inverters for unshaded uniform arrays. We explain the cost and monitoring tradeoff. | Microinverters are always best. |
| What does the shade analysis show for our roof across the year? | We run a shade analysis tool (HelioScope, Aurora, or similar) using a site survey and roof imagery, and we share the annual production estimate per panel with shade losses called out. | Shade is not significant. |
| Do you offer a production guarantee, and how is it enforced? | We offer an annual production guarantee in kWh based on the design model, and we explain the remediation path (true-up payment or system correction) if actual production falls below the threshold. | Production guarantees are a marketing gimmick. |
| What monitoring platform comes with the system, and are there subscription fees? | We name the monitoring platform (Enphase Enlighten, SolarEdge mySolarEdge, or similar), describe what data is visible per panel or per string, and disclose any optional or recurring fees. | Monitoring is included; do not worry about the details. |
| If we add a battery later, can we still apply for SGIP at that time? | Yes — SGIP applications are tied to the battery install, not the solar install. As of 2026, only the AB 209-funded RSSE (Residential Solar and Storage Equity) tier remains open to new applications, and that budget is fully reserved with new apps on a waitlist served via attrition; ratepayer-funded General Market / Equity / Equity Resiliency budgets are no longer accepting new applications. We verify current SGIP budget status at selfgenca.com when the battery is added and explain that pre-approval is required before equipment is delivered. | SGIP only counts if solar and battery are installed together. |
| Who handles the PG&E interconnection paperwork, and what is the typical timeline? | We submit the PG&E interconnection application on your behalf, file the city permits, and coordinate Permission to Operate (PTO). Typical PG&E PTO timelines range from 2 to 6 weeks after the city sign-off; we document the expected window in the quote. | Interconnection happens automatically. |
| What is your post-install commissioning checklist? | Commissioning includes verifying each panel reports correctly in the monitoring platform, checking inverter firmware, confirming production matches the design model on a clear day, and walking us through reading the monitoring app. | We turn it on and leave. |
| Will you pull the solar electrical and structural permits through SJPermits.org? | Yes. We pull the electrical and structural permits through SJPermits.org, itemize the fees in the quote, and schedule the final inspection. | Most solar installs do not need permits in California. |
| If we add a battery later, what permit work is required? | Adding a battery requires a separate electrical permit through SJPermits.org (and a structural permit if installed in conditioned interior space). We explain the inspection requirements per NEC Article 706 and CRC 1207 / R327 fire setback rules. | Battery additions are covered by the original solar permit. |
| How will you confirm the roof structure supports the array? | We perform a structural assessment including rafter sizing, spacing, and condition; for older or unusual roofs we may engage a licensed structural engineer to provide a letter for the permit submittal. | Roofs always handle solar. |
| How will the array meet California fire-setback rules? | We design the array to meet the California Residential Code fire access pathway requirements: ridge setbacks, hip-to-eave pathways, and emergency egress clearances, and we document compliance in the permit submittal. | Fire setbacks are optional. |
| What ongoing maintenance does the system need? | Typical maintenance is light: annual visual inspection, occasional rinse if local dust or pollen reduces production, and inverter firmware updates pushed by the manufacturer. We explain the warranty implications of skipping recommended maintenance. | Solar is install-and-forget; no maintenance ever. |
| What warranties cover the panels, inverter, and labor? | Panels typically carry a 25 year product warranty plus a 25 year linear production warranty; inverters carry 10 to 12 years standard (extendable); we provide a 5 to 10 year labor warranty separately. We document what voids each. | Lifetime warranty on everything. |
| Which circuits will be backed up during an outage, and for how long? | We provide a backup-loads list (refrigerator, internet, lights, HVAC controls, well pump if any), estimate runtime in hours at typical and worst-case usage, and explain whether whole-home or essential-loads backup is recommended. | The battery powers the house. |
| Does my install qualify for SGIP (Self-Generation Incentive Program), and at what tier? | We verify current SGIP budget status before quoting: as of December 31, 2025 the ratepayer-funded General Market, Equity, and Equity Resiliency budgets are closed to new applications, and only the AB 209-funded RSSE (Residential Solar and Storage Equity) tier remains open — and that budget is fully reserved with new applications served via an attrition-based waitlist (selfgenca.com). We document the waitlist position rather than promising a rebate, and we explain that pre-approval is required before equipment is delivered. | SGIP always pays out the maximum amount. |
| What is the battery's usable kWh and continuous inverter power, and how do they relate? | We specify both: kWh determines how long the backup lasts; the inverter's continuous AC output determines what can run at once (refrigerator + lights + maybe HVAC vs everything). | kWh is the only number that matters. |
| Is the battery AC-coupled or DC-coupled with the solar array, and why? | AC-coupled batteries use a separate inverter and are easier to retrofit to existing solar. DC-coupled batteries share an inverter with new solar and are typically more efficient end-to-end. We choose based on whether the solar array is new or existing. | Coupling does not matter. |
| Can we add more battery capacity later, and what are the limits? | Most modern systems support stacking additional units up to a vendor-specified maximum. We document the maximum stack today, what is needed to add capacity later (matching firmware, software update, possible electrical re-work), and whether SGIP can be applied to expansion units. | Buy the biggest battery today; expansion is impossible. |
| What depth-of-discharge limit does the battery use, and how does that affect usable kWh? | We explain the nameplate kWh vs usable kWh: modern LFP batteries reserve very little for cycle life (often 95 to 100 percent of nameplate is usable); older chemistries reserve 10 to 20 percent. We quote usable kWh in the proposal so you can compare like-for-like. | Nameplate kWh is the usable kWh. |
| What is the manufacturer warranty on the battery, and what limits it? | Most residential batteries carry a 10 to 12 year warranty, often paired with a cycle count (e.g. 6,000 to 10,000 cycles) or throughput limit (e.g. 37.8 MWh) - whichever comes first. We provide the spec sheet and explain what voids coverage. | Lifetime warranty; no fine print. |
| Are time-of-use arbitrage cycles counted against the warranty? | Yes. Every charge-discharge cycle counts toward the throughput limit; aggressive daily TOU arbitrage may shorten the years-based warranty window. We model expected cycles per year for your usage pattern. | Cycling does not count against the warranty. |
| How will the battery shift load away from PG&E peak hours? | We program the battery to charge from solar during midday and discharge during the PG&E EV2-A or E-ELEC peak window (typically 4-9pm), saving you the peak-period delta. We tune the schedule for your actual usage and rate plan. | The battery charges and discharges whenever. |
| How does NEM 3.0 change the battery payback? | Under NEM 3.0, export compensation dropped by roughly 75 percent, so self-consumption (using your solar via the battery instead of exporting) is now the primary battery economic driver. We model expected savings under NEM 3.0 with your specific rate plan. | NEM 3.0 has no effect on battery payback. |
| What permits are required for the battery install? | We pull the electrical permit through SJPermits.org. If the battery is installed in conditioned interior space we also pull a structural or building permit per local interpretation. We itemize the fees and schedule the inspection. | Battery installs do not need permits in San Jose. |
| Does an interior battery install need a structural or building permit in San Jose? | It depends on installation location and wall mounting. We confirm with the SJPermits.org plan reviewer whether a building or structural permit is required in addition to the electrical permit, and we document the answer in the quote. | Interior installs never need a building permit. |
| How will the install meet CRC 1207 / R327 fire-setback rules for energy storage? | We design the install per California Residential Code R327 (formerly section 1207): separation from windows, doors, openings into the dwelling, and other batteries; smoke and heat detectors per code; and an exterior wall location where possible. We document compliance in the permit submittal. | Fire setbacks are optional. |
| What is your post-install commissioning checklist? | Commissioning includes verifying battery state-of-charge reporting, testing backup-mode transfer with a simulated outage, walking through the app for backup-only vs TOU modes, and confirming the SGIP system performance metering is functioning if SGIP is part of the project. | We turn it on and leave. |
| Are you an installer certified by the battery manufacturer? | Yes. We provide our certification number for the specific battery brand (Tesla Powerwall, Enphase IQ, LG Chem RESU, FranklinWH, etc.); certification is typically required to preserve full warranty coverage. | Certification does not matter for batteries. |
| Who handles the PG&E interconnection update for the new battery? | We submit the updated PG&E interconnection paperwork to add the battery to your existing or new solar interconnection, and we obtain the updated Permission to Operate before energizing. | PG&E interconnection happens automatically. |
| What panel-side breaker work or interconnection method does the battery require? | We confirm whether the battery interconnects via a back-fed breaker (with sum-of-breakers check per NEC 705.12), a supply-side tap, or a dedicated battery sub-panel; we show the calculation on the permit drawings. | Any spare slot will work. |
Questions for electricians
| Question | Good response | Bad response |
|---|---|---|
| What is my panel size and service size, and is it adequate for adding a heat pump? | We inspect the panel labels and main breaker on site, explain whether 100A, 125A, 150A, or 200A is adequate, and verify the service drop matches the panel. | We guess from a photo only; no on-site inspection. |
| Can we avoid a service upgrade by using smart load management? | Possibly. We will perform a formal Article 220 load calculation, propose smart load management for HVAC + EV + water heater coordination, and explain the tradeoff vs upgrading. | You always need 200A; no calculation needed. |
| Will the heat pump need a new dedicated circuit, and what breaker size? | Yes, the outdoor unit and air handler each typically need dedicated circuits at the breaker sizes the manufacturer specifies (often 30-50A for outdoor, 15-30A for indoor). | Any spare breaker will work. |
| Will you pull the electrical permit, or do I need to? | We pull the electrical permit through SJPermits.org and coordinate with the mechanical permit; we itemize the fees in the quote. | You can do it without a permit. |
| Does the install require a dedicated electrical circuit, and what size? | Standard heat pump water heaters typically need a dedicated 30A 240V circuit; some 120V hybrid models can operate on a 15A or 20A circuit at reduced capacity. We size the circuit per the manufacturer's data plate and document conductor gauge and breaker rating in the quote. | Share the circuit with the dishwasher. |
| What charger amperage do you recommend, and why? | We size the charger based on your vehicle, expected daily mileage, panel capacity, and future second-EV plans (typically 32-48A continuous draw on a 40-60A circuit). | Always install the biggest charger; bigger is better. |
| Will the charger need a dedicated 240V circuit? | Yes. We run a dedicated 240V circuit sized at 125 percent of the charger's continuous draw, with the correct conductor gauge and conduit per code. | Share a circuit with the dryer. |
| How will you confirm my panel has capacity for the charger? | We perform an Article 220 load calculation on site, consider existing loads and planned heat pump or HVAC additions, and explain whether smart load management can avoid a service upgrade. | Your panel is fine; no calculation needed. |
| Can smart load management let me add a charger without upgrading the panel? | Often yes. Devices like Span panels or charger-side load-share modules may avoid a service upgrade by throttling the charger when other loads (HVAC, water heater) are active. | Load management is unreliable; always upgrade the panel. |
| How would you support a second EV without re-wiring everything later? | We may install a load-sharing charger today, or pre-pull conductors for a second circuit. We document the planned future load in the Article 220 calc. | One charger is plenty for any household. |
| Will you pull the electrical permit through SJPermits.org? | Yes, we pull the EV charger electrical permit through SJPermits.org and itemize the fee in the quote. | Most EV chargers don't need a permit. |
| How will you handle grounding and bonding for the new circuit? | We verify the service ground meets code, bond the charger neutral and equipment per Article 250, and confirm the GFCI protection (built in or required separately). | Grounding is standard; nothing to discuss. |
| Does the recommended charger support utility demand-response programs or scheduled charging? | We discuss WiFi-connected chargers that may integrate with PG&E EV2-A time-of-use rates and SJCE EV charging programs, and explain the user-side controls. | Smart features are gimmicks. |
| Where will the conduit run, and what does it cost to extend? | We walk the routing on site (interior wall vs exterior, attic vs trench), specify conduit fill code requirements, and itemize incremental cost per linear foot. | Conduit routing is included; don't worry about it. |
| What labor warranty do you provide on the install, separate from the manufacturer warranty? | We provide a 1-2 year labor warranty on installation; the manufacturer warranty (typically 3-5 years on the charger) is separate. | Lifetime warranty on everything. |
| Will you perform an NEC Article 220 load calculation before sizing the new panel or service? | Yes. We total existing connected loads, apply Article 220 demand factors, then add expected future loads (heat pump HVAC, heat pump water heater, EV charger, induction range, battery) before recommending a service size. | We size from the existing panel rating. |
| Is this a service upgrade or a panel-only replacement, and how do you decide? | We explain the difference plainly: a service upgrade changes the service drop, meter, and main breaker rating (utility coordination required); a panel-only replacement swaps the breaker box at the existing service rating. We base the recommendation on the Article 220 result, not on a default upsell. | It is the same thing. |
| Who coordinates with the utility for the service upgrade, and what lead time should we expect? | We coordinate with the serving utility (your investor-owned utility such as PG&E, SCE, or SDG&E, or your municipal utility such as LADWP or SMUD) for the service drop, meter swap, and any utility-side work. We document the expected utility lead time in the quote because it often dominates the project schedule. | The utility handles itself. |
| How do you decide between 200A, 225A, or 320A service, and how much headroom should we plan for? | We size to the Article 220 calculated demand plus headroom for the ten-year horizon of electrification projects already on the table. For most California single-family homes adding heat pump HVAC, heat pump water heater, and one or two EVs, a properly sized 200A service is enough; 225A or 320A is only justified when the load calc shows it. | Bigger is always better, so we go 320A. |
| When does a smart panel (Span, Lumin, Eaton EV Choice) make sense versus a standard load center? | A smart panel can avoid a service upgrade when load shedding can keep peak demand under the existing service rating, or when granular per-circuit metering is desired. A standard load center is the right choice when the Article 220 result already fits the service rating, the homeowner does not want app-based controls, or budget is tight. | Smart panels are always the answer. |
| Is a sub-panel addition (for a detached garage, ADU, or workshop) a viable alternative to a full service upgrade? | A sub-panel can serve outbuilding loads without changing the main service rating when the Article 220 calc shows the existing service still has capacity. We size the sub-panel feeder per NEC and run it under permit. | Sub-panels always require a service upgrade. |
| Will you inspect and update the grounding electrode system as part of the panel work? | Yes. We verify the grounding electrode system (ground rods, water-pipe bond, concrete-encased electrode where present), measure resistance where required, and upgrade conductors and connections to the current code edition adopted by your jurisdiction. | Grounding is fine if the panel is bonded. |
| Which circuits in the new panel will require AFCI or GFCI protection, and what code edition are you applying? | We apply the California Electrical Code edition currently adopted by your local AHJ (the California Electrical Code is based on the NEC with California amendments). We itemize AFCI-required and GFCI-required circuits and price the AFCI/GFCI breakers separately so the homeowner sees the cost driver. | AFCI rules are confusing, so we skip them. |
| Will the quote include whole-home surge protection, and which type? | We recommend a Type 2 surge protective device (SPD) integrated with the new panel as a standard line item; Type 1 SPD at the service entrance is an upgrade option for homes with frequent utility-side transients. We explain warranty terms and replacement procedure after a major surge event. | Surge protection is unnecessary. |
| Does the existing panel location meet current code clearances, or do we need to relocate it? | We measure NEC Article 110 working-clearance requirements (depth in front of the panel, clear width, headroom) and confirm the panel is not behind cabinets, in clothes closets, or in other prohibited locations. If the location does not meet current code, we quote the relocation. | The existing spot is fine because the old panel fit. |
| Will you use conduit or NM cable for the new circuits, and how do you decide? | We follow the California Electrical Code wiring methods permitted for residential occupancies. Conduit is required for exterior runs and where physical damage is likely; NM cable is permitted in many concealed interior runs. We size conductors for the future load, not just today's circuit. | Whatever is easiest and cheapest. |
| Who pulls the electrical permit at the local AHJ (city or county permit center), and is the fee itemized in your quote? | We pull the electrical permit at the local AHJ in our own name, attend the inspection, and itemize the permit fee in the quote. We do not ask the homeowner to pull the permit. | We do not pull permits because they slow the job. |
| Walk us through the inspection process: which inspections are required and what does each one check? | We typically schedule a rough-in inspection (panel mounted, grounding electrode system verified, conductors run) and a final inspection (devices terminated, AFCI/GFCI verified under test, labeling complete). The exact sequence depends on the local AHJ. | There is just one inspection at the end. |
| How long will the home be without power during the panel swap, and what time of day will it occur? | A panel-only swap typically takes 6 to 10 hours; a service upgrade with meter swap can take a full day and is constrained by the utility's window. We confirm the exact window and time-of-day with the utility before scheduling. | Will not take long. |
| Will the new panel be sized and labeled for future solar or battery interconnection per NEC Article 705.12? | Yes. We size the busbar and main breaker so the future solar PV and battery interconnection meets NEC Article 705.12 (the 120% rule or supply-side connection, depending on the configuration). We document the headroom available so the future installer can verify quickly. | Solar and battery do not affect panel sizing. |
| If we may add a generator interlock or transfer switch later, what should the new panel design account for? | We can include a generator interlock kit with the panel install, or pre-wire space for a future automatic transfer switch. Interlock is the lowest-cost option for occasional backup; ATS is the right path for whole-home automatic backup. | Generator readiness is a future problem. |
| How are you treating the federal §25C tax credit for panel-upgrade work? | The federal §25C Energy Efficient Home Improvement Credit expired December 31, 2025 under OBBBA (PL 119-21). For panel work performed in 2026 and later, we do not list §25C as an applicable credit and we will not claim eligibility. | You qualify for the 30 percent federal tax credit on panel work. |
| Is panel-upgrade work eligible for HEEHRA (Home Electrification and Appliance Rebates) in California, and what is the current funding status? | Panel-upgrade work, sub-panel additions, and electrical wiring needed to support qualifying electrification projects can be eligible HEEHRA expenses for income-qualified households. CPUC reported HEEHRA funds fully reserved earlier this year, so we do not promise current availability and confirm against the CPUC HEEHRA portal at quote time. | HEEHRA covers all panel upgrades automatically. |
| Are there TECH Clean California, CCA (Community Choice Aggregator), or utility-side incentives that apply to this panel work? | TECH Clean California is statewide for qualifying heat-pump installations; panel-upgrade work tied to a qualifying heat pump may be eligible. Many CCAs (such as MCE, SVCE, CleanPowerSF, SJCE) and IOUs run their own electrification rebates with panel-work eligibility. We confirm the program rules in writing before the quote and list each program with its reservation status. | All rebates are guaranteed if you sign today. |
| What is the manufacturer warranty on the new panel, breakers, and any smart-panel hardware? | We list the manufacturer warranty for the panel and main breaker (typically 10 years), branch-circuit breakers (typically 1 to 10 years), and smart-panel hardware separately. We explain what voids each. | Warranty is whatever the box says. |
| What is your labor warranty on the panel installation, and does it cover related troubleshooting? | We offer a written labor warranty (typically 1 to 5 years) covering workmanship on terminations, conduit runs, and grounding work. We explain what is covered and what is not. | Our work is good, no warranty needed. |
| Based on the Article 220 result, what do you recommend as the best next action and why? | We propose a single recommended option with the load-calc rationale, list one alternative with the cost delta, and explain what would change our recommendation. We are clear about which costs are firm and which depend on the utility or AHJ. | Whatever you want is fine. |
General questions for every contractor
| Question | Good response | Bad response |
|---|---|---|
| What permits does this installation require in San Jose? | A mechanical permit through SJPermits.org is required; an electrical permit is also required when a new dedicated circuit or panel work is involved. We handle both. | Heat pump installs don't need permits in California. |

| Does the federal Section 25D residential clean energy credit apply to my installation? | Section 25D expired December 31, 2025 under the One Big Beautiful Bill Act (Public Law 119-21). Installations completed in 2026 or later do not qualify for the 30 percent §25D credit. | You will receive the 30 percent federal credit on your taxes. |
| Does TECH Clean California currently offer a solar incentive? | TECH Clean California primarily targets heat pump HVAC and heat pump water heaters, not standalone solar. We verify current TECH program scope at techcleanca.com before citing any incentive. | TECH covers solar; assume the rebate applies. |
| Are BayREN Home+ rebates available for our solar or solar plus battery project? | BayREN Home+ is primarily a building shell and heat-pump program for Bay Area homeowners; we verify whether a solar or battery incentive is currently active at bayren.org and explain the application path if so. | BayREN always pays out for solar. |
| What is the best next step before signing a solar contract? | Get a written quote with line-item pricing including the design model output (kWh per year), shade analysis, panel and inverter make and model, permit and PG&E interconnection fees, production guarantee terms, and warranty terms. | Sign today to lock in pricing before incentives change. |
| Does the federal Section 25D residential clean energy credit apply to my battery install? | Section 25D expired December 31, 2025 under the One Big Beautiful Bill Act (Public Law 119-21). Battery installations completed in 2026 or later do not qualify for the 30 percent §25D credit. | You will receive the 30 percent federal credit on your taxes. |
| Does HEEHRA or TECH Clean California currently offer a battery incentive? | Neither HEEHRA nor TECH primarily fund residential batteries; SGIP is the main California battery program. We verify current TECH scope at techcleanca.com and HEEHRA status at energy.ca.gov before citing any battery incentive. | HEEHRA covers batteries automatically. |
| Will the quote separate confirmed SGIP incentives from assumed? | Yes. SGIP is marked confirmed only after pre-approval is granted and the funding tier is reserved; we mark the line as assumed in the quote until then and explain the reservation status. | All listed incentives are yours. |
| What is the best next step before signing a battery contract? | Get a written quote with line-item pricing including usable kWh, continuous AC inverter output, AC vs DC coupling, manufacturer warranty terms (years AND cycles AND throughput), labor warranty separately, SJPermits.org permit fees, PG&E interconnection plan, and an honest SGIP workflow: as of December 31, 2025 only the AB 209-funded RSSE budget accepts new applications and it is fully reserved (attrition-based waitlist via selfgenca.com), so the proposal documents the waitlist position rather than promising a rebate. | Sign today to lock in SGIP before funding runs out. |
| How much is the San Jose EV charger permit fee, and what does it cover? | We provide the current SJPermits.org fee in the quote and note it covers plan review (if any) plus the install inspection. | Permits are included; no fee discussion needed. |
| Does the federal §30C credit for EV charging equipment apply to my install? | §30C federal EV-charger credit had a statutory cliff on June 30, 2026 (OBBBA Public Law 119-21). Installations permitted and operational before that date may have qualified in eligible census tracts (low-income community or non-urban) — verify with your contractor and tax preparer. Installations after June 30, 2026 do not qualify. | You will receive the federal credit on your taxes. |
| Are PG&E EV charger rebates currently available? | PG&E's residential EV charger rebate program changes periodically; we verify current funding and program rules with PG&E before submitting on your behalf. | PG&E always pays out. |
| Are there SJCE EV charging programs or rebates worth applying for? | SJCE offers periodic EV charging incentives and time-of-use education; we verify current programs at sanjosecleanenergy.org and explain which apply to your install. | All SJCE programs are universal. |
| How does charging at home affect my PG&E rate plan options? | We explain PG&E EV2-A (EV-optimized TOU), E-ELEC, and SJCE generation tiers; we recommend running a rate-plan comparison after install based on actual charging patterns. | Your rate stays the same. |
| Will the quote separate confirmed incentives from assumed incentives? | Yes. Each incentive is marked confirmed (with program ID and current funding status) or assumed (subject to verification before contract signing). | All listed incentives are yours. |
| What is the warranty on the charger hardware, and what voids it? | The manufacturer typically warrants the charger for 3-5 years; we note that physical damage, surge events without a whole-home surge protector, and tampering may void coverage. | Warranty covers everything forever. |
| What is the inspection process after install? | We schedule the City of San Jose final inspection through SJPermits.org, are present for the inspection, and provide the signed inspection record before final payment. | Inspections are not necessary. |
| What is the best next step before signing a contract? | Get a written quote with line-item pricing including conduit footage, panel-capacity verification, an Article 220 load calc, and a clear permit and inspection plan. | Sign today to lock in pricing. |
| Should I plan for bidirectional (vehicle-to-home) charging now or later? | We may explain that bidirectional charging requires a charger with V2H or V2G capability plus a compatible EV; we recommend pre-pulling extra conductors only if you have a specific vehicle target. | Bidirectional is mandatory; install it now. |
Good vs reasonable vs bad answers
| Question | Good | Reasonable | Bad |
|---|---|---|---|
| Will you perform a Manual J load calculation before sizing the heat pump? | Yes. We calculate heating and cooling load based on home size, insulation, windows, orientation, ductwork, and infiltration. | We will run Manual J after a site visit and duct inspection. | We just replace the existing furnace with the same tonnage system. |
| Will you inspect ducts before specifying the heat pump? | Yes. We inspect duct size, leakage rate, return air paths, and airflow because heat pumps need good airflow at moderate static pressure. | We inspect ducts during install and modify if airflow targets are not met. | Ducts are always fine; no need to check. |
| How do you decide system size in tons or BTU? | We explain tons and BTU using Manual J inputs, not just square footage. | — | We use 1 ton per 500 square feet as a rule of thumb. |
| Will the heat pump cover both heating and cooling, and do we need backup heat? | Yes, a central heat pump provides both. We explain whether backup electric resistance heat is recommended for San Jose's mild winters. | — | Cooling is a separate system. |
| What refrigerant does the system use, and is it compliant with current EPA rules? | We specify the refrigerant (R-454B or R-32 for new systems after the EPA A2L transition) and confirm it meets current code. | — | Refrigerant does not affect homeowners. |
| What is the outdoor unit noise rating, and where will it be located? | We provide the published decibel rating, propose an installation location that meets San Jose's noise ordinance, and account for setback to property lines. | — | Heat pumps are quiet enough to put anywhere. |
| How will the heat pump perform during the coldest week of the year in San Jose? | We use the published HSPF2 or COP at the local design temperature (~41F for San Jose, the ASHRAE 99 percent heating design temperature), and confirm the system maintains capacity without significant backup heat usage during typical cold spells. | — | Heat pumps work fine in California. |
| Are you familiar with San Jose Clean Energy (SJCE) EcoHome rebates and how to coordinate them? | Yes, we may help homeowners apply for SJCE EcoHome rebates and confirm program availability before installation. | — | All rebates are guaranteed; we will get them for you. |
| Are you a TECH Clean California enrolled contractor, and is the program currently funded for heat pump HVAC? | We verify current TECH Clean California program status (single-family Phase I has been fully reserved since November 2025) and explain whether it applies before signing. | — | TECH always pays out; assume the rebate is yours. |
| Does my household income make us eligible for HEEHRA, and what does that involve? | We confirm income eligibility (below 80 percent AMI or 80 to 150 percent AMI), explain pre-approval is required, and verify program status (Phase I single-family is currently fully reserved per CEC as of 2026-02-24). | HEEHRA may apply if eligibility is verified after a site visit and income documentation. | HEEHRA covers everyone; you qualify automatically. |
| What is my panel size and service size, and is it adequate for adding a heat pump? | We inspect the panel labels and main breaker on site, explain whether 100A, 125A, 150A, or 200A is adequate, and verify the service drop matches the panel. | — | We guess from a photo only; no on-site inspection. |
| Can we avoid a service upgrade by using smart load management? | Possibly. We will perform a formal Article 220 load calculation, propose smart load management for HVAC + EV + water heater coordination, and explain the tradeoff vs upgrading. | We need to see your panel labels and load history before recommending. | You always need 200A; no calculation needed. |
| Will the heat pump need a new dedicated circuit, and what breaker size? | Yes, the outdoor unit and air handler each typically need dedicated circuits at the breaker sizes the manufacturer specifies (often 30-50A for outdoor, 15-30A for indoor). | — | Any spare breaker will work. |
| Will you pull the electrical permit, or do I need to? | We pull the electrical permit through SJPermits.org and coordinate with the mechanical permit; we itemize the fees in the quote. | — | You can do it without a permit. |
| What permits does this installation require in San Jose? | A mechanical permit through SJPermits.org is required; an electrical permit is also required when a new dedicated circuit or panel work is involved. We handle both. | — | Heat pump installs don't need permits in California. |
| Can you separate confirmed incentives from assumed incentives in the quote? | Yes. We mark each incentive as confirmed (with program ID and current reservation status) versus assumed (subject to verification before contract). | — | All listed incentives are yours. |
| Does the federal Section 25C tax credit apply to my installation? | Section 25C expired December 31, 2025 under the One Big Beautiful Bill Act (Public Law 119-21). Installations completed in 2026 or later do not qualify for §25C. | — | You'll get the federal credit on your taxes. |
| Are BayREN Home+ rebates available for this installation? | BayREN Home+ may apply for Bay Area homeowners; we verify the program is currently funded and that the equipment qualifies before submitting. | — | BayREN always pays out automatically. |
| What is the equipment and labor warranty, and what voids it? | We provide the manufacturer warranty (typically 10 years parts when registered) plus our labor warranty (1-2 years standard); we explain what voids coverage including improper electrical, missing filters, and skipped annual service. | — | The warranty covers everything forever. |
| What is the best next step before signing a contract? | Schedule a site visit and Manual J load calculation, get a written quote with line-item pricing, verify all incentive reservation requirements, and confirm permit handling. | — | Sign today to lock in pricing before incentives expire. |
| Where will the heat pump water heater go, and does the location have adequate air volume? | We assess garage and utility room candidates (heat pump water heaters need roughly 700 to 1000 cubic feet of conditioned air around the unit, or a ducted exhaust path), evaluate noise impact, and confirm clearance per the manufacturer's install manual. | — | Any closet works for a heat pump water heater. |
| How will you handle the condensate drain? | We route a gravity drain to an approved disposal location or use a condensate pump; we explain freeze risk and overflow safety per CPC, and itemize the work in the quote. | — | Condensate isn't really an issue. |
| Does the install require a dedicated electrical circuit, and what size? | Standard heat pump water heaters typically need a dedicated 30A 240V circuit; some 120V hybrid models can operate on a 15A or 20A circuit at reduced capacity. We size the circuit per the manufacturer's data plate and document conductor gauge and breaker rating in the quote. | — | Share the circuit with the dishwasher. |
| How will you size the tank, 50, 65, or 80 gallons? | We size from household occupancy, peak-hour fixture demand (showers, dishwasher, clothes washer simultaneity), and recovery preferences. A typical 3-to-4-person household lands on a 65 or 80 gallon unit to compensate for slower heat pump recovery vs gas. | — | Match the gallons of whatever tank is there now. |
| What is the first-hour rating of the proposed unit, and is it sufficient for our peak demand? | We provide the manufacturer's first-hour rating (gallons delivered in the first hour of peak use) and compare it to your typical morning or evening peak demand. We may suggest a larger tank or a mixing valve strategy when the rating runs tight. | — | First-hour rating isn't really relevant. |
| What is the Uniform Energy Factor (UEF) of the proposed unit, and how does it affect rebate eligibility? | We document the UEF on the spec sheet (modern heat pump water heaters typically range 3.0 to 4.0+ UEF). Many rebates require UEF at or above a threshold (often 3.0) or a NEEA Advanced Water Heater Specification tier rating; we confirm the eligible tier before submitting. | — | UEF doesn't matter for rebates. |
| Will the install be ambient (drawing from the room) or ducted? | Ambient installs are simplest and cheapest in a garage or large utility room. Conditioned-space installs may need ducted intake or exhaust to avoid cooling the living space; ducting adds labor and material cost. We model the tradeoff in the quote. | — | Ducting is always required. |
| What operating modes does the unit support, and which one do you recommend by default? | Most modern units offer heat-pump-only (most efficient), hybrid (heat pump plus resistance backup on high demand), and resistance-only (emergency or cold-snap) modes. We recommend hybrid as a default and explain how mode choice changes runtime and operating cost. | — | Modes are a gimmick; leave it on resistance. |
| What is the manufacturer warranty on the tank, the heat pump compressor, and labor? | Most residential heat pump water heaters carry a 10-year tank warranty and a separate compressor warranty (often shorter). We provide the spec sheet and itemize our labor warranty separately so they aren't confused. | — | Lifetime warranty; no fine print. |
| Does HEEHRA currently offer a rebate for heat pump water heaters? | Heat pump water heaters are a HEEHRA-eligible category statewide; CPUC reservations for HEEHRA were fully subscribed as of February 2026. We verify current status at energy.ca.gov and may mark HEEHRA as assumed until a reservation is confirmed. | — | HEEHRA pays out automatically for every install. |
| Does the unit qualify for TECH Clean California, and what is the current status? | TECH Clean California covers qualifying heat pump water heaters statewide; we verify current scope, eligible model lists, and per-unit incentive amount at techcleanca.com before citing a number in the quote. | — | TECH covers every model on the market. |
| Does the BayREN Home+ program offer a rebate path for heat pump water heaters? | BayREN Home+ has historically offered a heat pump water heater rebate for Bay Area homeowners. We verify current program scope and rebate amount at bayrenhomes.org before submitting. | — | BayREN funds every Bay Area install at the same amount. |
| Are there SJCE EcoHome incentives that stack with the state and federal programs? | San Jose Clean Energy's EcoHome program periodically funds heat pump water heater incentives for SJCE customers. We confirm current EcoHome funding at sanjosecleanenergy.org and document any stacking rules with HEEHRA, TECH, or BayREN. | — | EcoHome incentives are unlimited. |
| Does the federal Section 25C credit apply to the install? | Section 25C expired December 31, 2025 under the One Big Beautiful Bill Act (Public Law 119-21). Heat pump water heater installations completed in 2026 or later do not qualify for the §25C federal tax credit. | — | The federal credit applies as long as you install before tax day. |
| Who coordinates the plumber and electrician — your team or me? | We coordinate plumber and electrician scheduling under a single project lead, sequence the work so electrical and plumbing don't conflict, and present a unified quote with both trades line-itemed. | — | You hire and coordinate the electrician separately. |
| If we are switching from gas, how will you decommission the gas line? | We cap and label the abandoned gas line per CPC, pressure-test or visually verify the cap, and remove the abandoned T&P discharge pipe if it conflicts with the new install. The work is itemized in the quote. | — | Just leave the old gas line where it is. |
| What permits are required, and who pulls them? | San Jose requires both a mechanical and an electrical permit for a heat pump water heater install. We pull both through SJPermits.org, itemize fees, and present the inspection card before final payment. | — | Water heater swaps don't need permits. |
| What is your post-install commissioning checklist? | Commissioning includes pressure testing the plumbing, verifying the T&P relief valve and discharge routing, confirming the condensate drain runs free, setting the default operating mode, and walking through the app and any user controls. | — | We turn it on and leave. |
| What is the expected recovery time after a high-demand event, like back-to-back showers? | In heat-pump-only mode, recovery is slower than gas (typically 2 to 3 hours to reheat a depleted tank). Hybrid mode shortens that. We explain mode tradeoffs and may recommend a larger tank or a mixing valve strategy when recovery is a concern. | — | Recovery is the same as gas; no tradeoff. |
| Will the quote separate confirmed incentives from assumed incentives? | Yes. Each incentive line shows program ID, reservation status (confirmed vs assumed), and a verify-by date. HEEHRA, TECH, BayREN, and SJCE EcoHome are commonly marked assumed until reservation is granted. | — | All listed incentives are yours. |
| What is the best next step before signing a heat pump water heater contract? | Get a written quote with line-item pricing covering model, capacity in gallons, first-hour rating, UEF, install location and ducting plan, dedicated electrical circuit, condensate drain plan, gas decommissioning (if applicable), SJPermits.org mechanical and electrical permit fees, and incentives separated into confirmed vs assumed with verify-by dates. | — | Sign today to lock in the incentive before it runs out. |
| How will you size the solar array for our future electric load (heat pump HVAC, EV, water heater)? | We model expected future usage including planned heat pump, EV miles, and water heater, then size the array to offset that load under NEM 3.0 export economics. | — | We size the system from last year's utility bill only. |
| How does NEM 3.0 change the economics versus older interconnections? | NEM 3.0 cut export compensation by ~75 percent versus NEM 2.0, which makes battery storage important for self-consumption. We model expected savings under NEM 3.0 specifically. | — | NEM 3.0 is the same as NEM 2.0 economically. |
| Is my roof suitable for solar, and what is its remaining lifetime? | We inspect the roof condition, slope, orientation, and shade pattern; we recommend roof replacement first if the roof is near end of life. | — | Any roof works. |
| Which panel and inverter brands do you recommend, and why? | We name the specific panel model (wattage, efficiency, temperature coefficient, degradation curve) and inverter brand (string vs microinverter), explain the tradeoffs for our roof, and provide the manufacturer datasheets. | — | We use whatever is cheapest in stock this month. |
| Will the array use string inverters, microinverters, or DC optimizers, and why? | We choose based on roof shading patterns and orientation: microinverters or optimizers for shaded or multi-orientation roofs, string inverters for unshaded uniform arrays. We explain the cost and monitoring tradeoff. | — | Microinverters are always best. |
| What does the shade analysis show for our roof across the year? | We run a shade analysis tool (HelioScope, Aurora, or similar) using a site survey and roof imagery, and we share the annual production estimate per panel with shade losses called out. | — | Shade is not significant. |
| Do you offer a production guarantee, and how is it enforced? | We offer an annual production guarantee in kWh based on the design model, and we explain the remediation path (true-up payment or system correction) if actual production falls below the threshold. | — | Production guarantees are a marketing gimmick. |
| What monitoring platform comes with the system, and are there subscription fees? | We name the monitoring platform (Enphase Enlighten, SolarEdge mySolarEdge, or similar), describe what data is visible per panel or per string, and disclose any optional or recurring fees. | — | Monitoring is included; do not worry about the details. |
| If we add a battery later, can we still apply for SGIP at that time? | Yes — SGIP applications are tied to the battery install, not the solar install. As of 2026, only the AB 209-funded RSSE (Residential Solar and Storage Equity) tier remains open to new applications, and that budget is fully reserved with new apps on a waitlist served via attrition; ratepayer-funded General Market / Equity / Equity Resiliency budgets are no longer accepting new applications. We verify current SGIP budget status at selfgenca.com when the battery is added and explain that pre-approval is required before equipment is delivered. | — | SGIP only counts if solar and battery are installed together. |
| Does the federal Section 25D residential clean energy credit apply to my installation? | Section 25D expired December 31, 2025 under the One Big Beautiful Bill Act (Public Law 119-21). Installations completed in 2026 or later do not qualify for the 30 percent §25D credit. | — | You will receive the 30 percent federal credit on your taxes. |
| Does TECH Clean California currently offer a solar incentive? | TECH Clean California primarily targets heat pump HVAC and heat pump water heaters, not standalone solar. We verify current TECH program scope at techcleanca.com before citing any incentive. | — | TECH covers solar; assume the rebate applies. |
| Are BayREN Home+ rebates available for our solar or solar plus battery project? | BayREN Home+ is primarily a building shell and heat-pump program for Bay Area homeowners; we verify whether a solar or battery incentive is currently active at bayren.org and explain the application path if so. | — | BayREN always pays out for solar. |
| Who handles the PG&E interconnection paperwork, and what is the typical timeline? | We submit the PG&E interconnection application on your behalf, file the city permits, and coordinate Permission to Operate (PTO). Typical PG&E PTO timelines range from 2 to 6 weeks after the city sign-off; we document the expected window in the quote. | — | Interconnection happens automatically. |
| What is your post-install commissioning checklist? | Commissioning includes verifying each panel reports correctly in the monitoring platform, checking inverter firmware, confirming production matches the design model on a clear day, and walking us through reading the monitoring app. | — | We turn it on and leave. |
| Will you pull the solar electrical and structural permits through SJPermits.org? | Yes. We pull the electrical and structural permits through SJPermits.org, itemize the fees in the quote, and schedule the final inspection. | — | Most solar installs do not need permits in California. |
| If we add a battery later, what permit work is required? | Adding a battery requires a separate electrical permit through SJPermits.org (and a structural permit if installed in conditioned interior space). We explain the inspection requirements per NEC Article 706 and CRC 1207 / R327 fire setback rules. | — | Battery additions are covered by the original solar permit. |
| How will you confirm the roof structure supports the array? | We perform a structural assessment including rafter sizing, spacing, and condition; for older or unusual roofs we may engage a licensed structural engineer to provide a letter for the permit submittal. | — | Roofs always handle solar. |
| How will the array meet California fire-setback rules? | We design the array to meet the California Residential Code fire access pathway requirements: ridge setbacks, hip-to-eave pathways, and emergency egress clearances, and we document compliance in the permit submittal. | — | Fire setbacks are optional. |
| What ongoing maintenance does the system need? | Typical maintenance is light: annual visual inspection, occasional rinse if local dust or pollen reduces production, and inverter firmware updates pushed by the manufacturer. We explain the warranty implications of skipping recommended maintenance. | — | Solar is install-and-forget; no maintenance ever. |
| What warranties cover the panels, inverter, and labor? | Panels typically carry a 25 year product warranty plus a 25 year linear production warranty; inverters carry 10 to 12 years standard (extendable); we provide a 5 to 10 year labor warranty separately. We document what voids each. | — | Lifetime warranty on everything. |
| What is the best next step before signing a solar contract? | Get a written quote with line-item pricing including the design model output (kWh per year), shade analysis, panel and inverter make and model, permit and PG&E interconnection fees, production guarantee terms, and warranty terms. | — | Sign today to lock in pricing before incentives change. |
| Which circuits will be backed up during an outage, and for how long? | We provide a backup-loads list (refrigerator, internet, lights, HVAC controls, well pump if any), estimate runtime in hours at typical and worst-case usage, and explain whether whole-home or essential-loads backup is recommended. | — | The battery powers the house. |
| Does my install qualify for SGIP (Self-Generation Incentive Program), and at what tier? | We verify current SGIP budget status before quoting: as of December 31, 2025 the ratepayer-funded General Market, Equity, and Equity Resiliency budgets are closed to new applications, and only the AB 209-funded RSSE (Residential Solar and Storage Equity) tier remains open — and that budget is fully reserved with new applications served via an attrition-based waitlist (selfgenca.com). We document the waitlist position rather than promising a rebate, and we explain that pre-approval is required before equipment is delivered. | — | SGIP always pays out the maximum amount. |
| What is the battery's usable kWh and continuous inverter power, and how do they relate? | We specify both: kWh determines how long the backup lasts; the inverter's continuous AC output determines what can run at once (refrigerator + lights + maybe HVAC vs everything). | — | kWh is the only number that matters. |
| Is the battery AC-coupled or DC-coupled with the solar array, and why? | AC-coupled batteries use a separate inverter and are easier to retrofit to existing solar. DC-coupled batteries share an inverter with new solar and are typically more efficient end-to-end. We choose based on whether the solar array is new or existing. | — | Coupling does not matter. |
| Can we add more battery capacity later, and what are the limits? | Most modern systems support stacking additional units up to a vendor-specified maximum. We document the maximum stack today, what is needed to add capacity later (matching firmware, software update, possible electrical re-work), and whether SGIP can be applied to expansion units. | — | Buy the biggest battery today; expansion is impossible. |
| What depth-of-discharge limit does the battery use, and how does that affect usable kWh? | We explain the nameplate kWh vs usable kWh: modern LFP batteries reserve very little for cycle life (often 95 to 100 percent of nameplate is usable); older chemistries reserve 10 to 20 percent. We quote usable kWh in the proposal so you can compare like-for-like. | — | Nameplate kWh is the usable kWh. |
| What is the manufacturer warranty on the battery, and what limits it? | Most residential batteries carry a 10 to 12 year warranty, often paired with a cycle count (e.g. 6,000 to 10,000 cycles) or throughput limit (e.g. 37.8 MWh) - whichever comes first. We provide the spec sheet and explain what voids coverage. | — | Lifetime warranty; no fine print. |
| Are time-of-use arbitrage cycles counted against the warranty? | Yes. Every charge-discharge cycle counts toward the throughput limit; aggressive daily TOU arbitrage may shorten the years-based warranty window. We model expected cycles per year for your usage pattern. | — | Cycling does not count against the warranty. |
| How will the battery shift load away from PG&E peak hours? | We program the battery to charge from solar during midday and discharge during the PG&E EV2-A or E-ELEC peak window (typically 4-9pm), saving you the peak-period delta. We tune the schedule for your actual usage and rate plan. | — | The battery charges and discharges whenever. |
| How does NEM 3.0 change the battery payback? | Under NEM 3.0, export compensation dropped by roughly 75 percent, so self-consumption (using your solar via the battery instead of exporting) is now the primary battery economic driver. We model expected savings under NEM 3.0 with your specific rate plan. | — | NEM 3.0 has no effect on battery payback. |
| What permits are required for the battery install? | We pull the electrical permit through SJPermits.org. If the battery is installed in conditioned interior space we also pull a structural or building permit per local interpretation. We itemize the fees and schedule the inspection. | — | Battery installs do not need permits in San Jose. |
| Does an interior battery install need a structural or building permit in San Jose? | It depends on installation location and wall mounting. We confirm with the SJPermits.org plan reviewer whether a building or structural permit is required in addition to the electrical permit, and we document the answer in the quote. | — | Interior installs never need a building permit. |
| How will the install meet CRC 1207 / R327 fire-setback rules for energy storage? | We design the install per California Residential Code R327 (formerly section 1207): separation from windows, doors, openings into the dwelling, and other batteries; smoke and heat detectors per code; and an exterior wall location where possible. We document compliance in the permit submittal. | — | Fire setbacks are optional. |
| What is your post-install commissioning checklist? | Commissioning includes verifying battery state-of-charge reporting, testing backup-mode transfer with a simulated outage, walking through the app for backup-only vs TOU modes, and confirming the SGIP system performance metering is functioning if SGIP is part of the project. | — | We turn it on and leave. |
| Are you an installer certified by the battery manufacturer? | Yes. We provide our certification number for the specific battery brand (Tesla Powerwall, Enphase IQ, LG Chem RESU, FranklinWH, etc.); certification is typically required to preserve full warranty coverage. | — | Certification does not matter for batteries. |
| Who handles the PG&E interconnection update for the new battery? | We submit the updated PG&E interconnection paperwork to add the battery to your existing or new solar interconnection, and we obtain the updated Permission to Operate before energizing. | — | PG&E interconnection happens automatically. |
| What panel-side breaker work or interconnection method does the battery require? | We confirm whether the battery interconnects via a back-fed breaker (with sum-of-breakers check per NEC 705.12), a supply-side tap, or a dedicated battery sub-panel; we show the calculation on the permit drawings. | — | Any spare slot will work. |
| Does the federal Section 25D residential clean energy credit apply to my battery install? | Section 25D expired December 31, 2025 under the One Big Beautiful Bill Act (Public Law 119-21). Battery installations completed in 2026 or later do not qualify for the 30 percent §25D credit. | — | You will receive the 30 percent federal credit on your taxes. |
| Does HEEHRA or TECH Clean California currently offer a battery incentive? | Neither HEEHRA nor TECH primarily fund residential batteries; SGIP is the main California battery program. We verify current TECH scope at techcleanca.com and HEEHRA status at energy.ca.gov before citing any battery incentive. | — | HEEHRA covers batteries automatically. |
| Will the quote separate confirmed SGIP incentives from assumed? | Yes. SGIP is marked confirmed only after pre-approval is granted and the funding tier is reserved; we mark the line as assumed in the quote until then and explain the reservation status. | — | All listed incentives are yours. |
| What is the best next step before signing a battery contract? | Get a written quote with line-item pricing including usable kWh, continuous AC inverter output, AC vs DC coupling, manufacturer warranty terms (years AND cycles AND throughput), labor warranty separately, SJPermits.org permit fees, PG&E interconnection plan, and an honest SGIP workflow: as of December 31, 2025 only the AB 209-funded RSSE budget accepts new applications and it is fully reserved (attrition-based waitlist via selfgenca.com), so the proposal documents the waitlist position rather than promising a rebate. | — | Sign today to lock in SGIP before funding runs out. |
| What charger amperage do you recommend, and why? | We size the charger based on your vehicle, expected daily mileage, panel capacity, and future second-EV plans (typically 32-48A continuous draw on a 40-60A circuit). | — | Always install the biggest charger; bigger is better. |
| Will the charger need a dedicated 240V circuit? | Yes. We run a dedicated 240V circuit sized at 125 percent of the charger's continuous draw, with the correct conductor gauge and conduit per code. | — | Share a circuit with the dryer. |
| How will you confirm my panel has capacity for the charger? | We perform an Article 220 load calculation on site, consider existing loads and planned heat pump or HVAC additions, and explain whether smart load management can avoid a service upgrade. | — | Your panel is fine; no calculation needed. |
| Can smart load management let me add a charger without upgrading the panel? | Often yes. Devices like Span panels or charger-side load-share modules may avoid a service upgrade by throttling the charger when other loads (HVAC, water heater) are active. | — | Load management is unreliable; always upgrade the panel. |
| How would you support a second EV without re-wiring everything later? | We may install a load-sharing charger today, or pre-pull conductors for a second circuit. We document the planned future load in the Article 220 calc. | — | One charger is plenty for any household. |
| Will you pull the electrical permit through SJPermits.org? | Yes, we pull the EV charger electrical permit through SJPermits.org and itemize the fee in the quote. | — | Most EV chargers don't need a permit. |
| How will you handle grounding and bonding for the new circuit? | We verify the service ground meets code, bond the charger neutral and equipment per Article 250, and confirm the GFCI protection (built in or required separately). | — | Grounding is standard; nothing to discuss. |
| Does the recommended charger support utility demand-response programs or scheduled charging? | We discuss WiFi-connected chargers that may integrate with PG&E EV2-A time-of-use rates and SJCE EV charging programs, and explain the user-side controls. | — | Smart features are gimmicks. |
| Where will the conduit run, and what does it cost to extend? | We walk the routing on site (interior wall vs exterior, attic vs trench), specify conduit fill code requirements, and itemize incremental cost per linear foot. | — | Conduit routing is included; don't worry about it. |
| What labor warranty do you provide on the install, separate from the manufacturer warranty? | We provide a 1-2 year labor warranty on installation; the manufacturer warranty (typically 3-5 years on the charger) is separate. | — | Lifetime warranty on everything. |
| How much is the San Jose EV charger permit fee, and what does it cover? | We provide the current SJPermits.org fee in the quote and note it covers plan review (if any) plus the install inspection. | — | Permits are included; no fee discussion needed. |
| Does the federal §30C credit for EV charging equipment apply to my install? | §30C federal EV-charger credit had a statutory cliff on June 30, 2026 (OBBBA Public Law 119-21). Installations permitted and operational before that date may have qualified in eligible census tracts (low-income community or non-urban) — verify with your contractor and tax preparer. Installations after June 30, 2026 do not qualify. | — | You will receive the federal credit on your taxes. |
| Are PG&E EV charger rebates currently available? | PG&E's residential EV charger rebate program changes periodically; we verify current funding and program rules with PG&E before submitting on your behalf. | — | PG&E always pays out. |
| Are there SJCE EV charging programs or rebates worth applying for? | SJCE offers periodic EV charging incentives and time-of-use education; we verify current programs at sanjosecleanenergy.org and explain which apply to your install. | — | All SJCE programs are universal. |
| How does charging at home affect my PG&E rate plan options? | We explain PG&E EV2-A (EV-optimized TOU), E-ELEC, and SJCE generation tiers; we recommend running a rate-plan comparison after install based on actual charging patterns. | — | Your rate stays the same. |
| Will the quote separate confirmed incentives from assumed incentives? | Yes. Each incentive is marked confirmed (with program ID and current funding status) or assumed (subject to verification before contract signing). | — | All listed incentives are yours. |
| What is the warranty on the charger hardware, and what voids it? | The manufacturer typically warrants the charger for 3-5 years; we note that physical damage, surge events without a whole-home surge protector, and tampering may void coverage. | — | Warranty covers everything forever. |
| What is the inspection process after install? | We schedule the City of San Jose final inspection through SJPermits.org, are present for the inspection, and provide the signed inspection record before final payment. | — | Inspections are not necessary. |
| What is the best next step before signing a contract? | Get a written quote with line-item pricing including conduit footage, panel-capacity verification, an Article 220 load calc, and a clear permit and inspection plan. | — | Sign today to lock in pricing. |
| Should I plan for bidirectional (vehicle-to-home) charging now or later? | We may explain that bidirectional charging requires a charger with V2H or V2G capability plus a compatible EV; we recommend pre-pulling extra conductors only if you have a specific vehicle target. | — | Bidirectional is mandatory; install it now. |
| Will you perform an NEC Article 220 load calculation before sizing the new panel or service? | Yes. We total existing connected loads, apply Article 220 demand factors, then add expected future loads (heat pump HVAC, heat pump water heater, EV charger, induction range, battery) before recommending a service size. | We perform the Article 220 calculation during the site visit and share the worksheet with the quote. | We size from the existing panel rating. |
| Is this a service upgrade or a panel-only replacement, and how do you decide? | We explain the difference plainly: a service upgrade changes the service drop, meter, and main breaker rating (utility coordination required); a panel-only replacement swaps the breaker box at the existing service rating. We base the recommendation on the Article 220 result, not on a default upsell. | We confirm after the load calc whether the existing service amperage is adequate; if it is, we propose a panel-only replacement. | It is the same thing. |
| Who coordinates with the utility for the service upgrade, and what lead time should we expect? | We coordinate with the serving utility (your investor-owned utility such as PG&E, SCE, or SDG&E, or your municipal utility such as LADWP or SMUD) for the service drop, meter swap, and any utility-side work. We document the expected utility lead time in the quote because it often dominates the project schedule. | We open the utility ticket after permit issuance and update the schedule when the utility confirms its lead time. | The utility handles itself. |
| How do you decide between 200A, 225A, or 320A service, and how much headroom should we plan for? | We size to the Article 220 calculated demand plus headroom for the ten-year horizon of electrification projects already on the table. For most California single-family homes adding heat pump HVAC, heat pump water heater, and one or two EVs, a properly sized 200A service is enough; 225A or 320A is only justified when the load calc shows it. | We present two options with the load-calc deltas so the homeowner can decide between 200A and 225A. | Bigger is always better, so we go 320A. |
| When does a smart panel (Span, Lumin, Eaton EV Choice) make sense versus a standard load center? | A smart panel can avoid a service upgrade when load shedding can keep peak demand under the existing service rating, or when granular per-circuit metering is desired. A standard load center is the right choice when the Article 220 result already fits the service rating, the homeowner does not want app-based controls, or budget is tight. | We model both options against the load calc and present the cost delta plus tradeoffs. | Smart panels are always the answer. |
| Is a sub-panel addition (for a detached garage, ADU, or workshop) a viable alternative to a full service upgrade? | A sub-panel can serve outbuilding loads without changing the main service rating when the Article 220 calc shows the existing service still has capacity. We size the sub-panel feeder per NEC and run it under permit. | We compare a sub-panel addition against a service upgrade with the load-calc results, then recommend the option that fits the future plan. | Sub-panels always require a service upgrade. |
| Will you inspect and update the grounding electrode system as part of the panel work? | Yes. We verify the grounding electrode system (ground rods, water-pipe bond, concrete-encased electrode where present), measure resistance where required, and upgrade conductors and connections to the current code edition adopted by your jurisdiction. | We inspect the grounding electrode system during the rough-in and bring it to current code if any element is deficient. | Grounding is fine if the panel is bonded. |
| Which circuits in the new panel will require AFCI or GFCI protection, and what code edition are you applying? | We apply the California Electrical Code edition currently adopted by your local AHJ (the California Electrical Code is based on the NEC with California amendments). We itemize AFCI-required and GFCI-required circuits and price the AFCI/GFCI breakers separately so the homeowner sees the cost driver. | We apply AFCI and GFCI rules per the current adopted code edition and confirm exact requirements during permit submittal. | AFCI rules are confusing, so we skip them. |
| Will the quote include whole-home surge protection, and which type? | We recommend a Type 2 surge protective device (SPD) integrated with the new panel as a standard line item; Type 1 SPD at the service entrance is an upgrade option for homes with frequent utility-side transients. We explain warranty terms and replacement procedure after a major surge event. | We include a Type 2 SPD with the panel and price a Type 1 SPD upgrade separately. | Surge protection is unnecessary. |
| Does the existing panel location meet current code clearances, or do we need to relocate it? | We measure NEC Article 110 working-clearance requirements (depth in front of the panel, clear width, headroom) and confirm the panel is not behind cabinets, in clothes closets, or in other prohibited locations. If the location does not meet current code, we quote the relocation. | We verify clearance during the site visit and quote relocation only if the current spot does not meet code. | The existing spot is fine because the old panel fit. |
| Will you use conduit or NM cable for the new circuits, and how do you decide? | We follow the California Electrical Code wiring methods permitted for residential occupancies. Conduit is required for exterior runs and where physical damage is likely; NM cable is permitted in many concealed interior runs. We size conductors for the future load, not just today's circuit. | We follow code wiring methods and explain any conduit upgrades that affect the price. | Whatever is easiest and cheapest. |
| Who pulls the electrical permit at the local AHJ (city or county permit center), and is the fee itemized in your quote? | We pull the electrical permit at the local AHJ in our own name, attend the inspection, and itemize the permit fee in the quote. We do not ask the homeowner to pull the permit. | We pull the permit at the local AHJ and break out the fee on the quote. | We do not pull permits because they slow the job. |
| Walk us through the inspection process: which inspections are required and what does each one check? | We typically schedule a rough-in inspection (panel mounted, grounding electrode system verified, conductors run) and a final inspection (devices terminated, AFCI/GFCI verified under test, labeling complete). The exact sequence depends on the local AHJ. | We confirm the inspection sequence with the AHJ at permit submittal and update the homeowner on the schedule. | There is just one inspection at the end. |
| How long will the home be without power during the panel swap, and what time of day will it occur? | A panel-only swap typically takes 6 to 10 hours; a service upgrade with meter swap can take a full day and is constrained by the utility's window. We confirm the exact window and time-of-day with the utility before scheduling. | We give a window once the utility confirms the meter swap appointment. | Will not take long. |
| Will the new panel be sized and labeled for future solar or battery interconnection per NEC Article 705.12? | Yes. We size the busbar and main breaker so the future solar PV and battery interconnection meets NEC Article 705.12 (the 120% rule or supply-side connection, depending on the configuration). We document the headroom available so the future installer can verify quickly. | We confirm Article 705.12 compatibility during design and note the calculated headroom on the panel schedule. | Solar and battery do not affect panel sizing. |
| If we may add a generator interlock or transfer switch later, what should the new panel design account for? | We can include a generator interlock kit with the panel install, or pre-wire space for a future automatic transfer switch. Interlock is the lowest-cost option for occasional backup; ATS is the right path for whole-home automatic backup. | We pre-wire space for a future interlock or transfer switch if requested, and note it on the panel schedule. | Generator readiness is a future problem. |
| How are you treating the federal §25C tax credit for panel-upgrade work? | The federal §25C Energy Efficient Home Improvement Credit expired December 31, 2025 under OBBBA (PL 119-21). For panel work performed in 2026 and later, we do not list §25C as an applicable credit and we will not claim eligibility. | We confirm the current federal-credit status against the IRS guidance at quote time and update the homeowner. | You qualify for the 30 percent federal tax credit on panel work. |
| Is panel-upgrade work eligible for HEEHRA (Home Electrification and Appliance Rebates) in California, and what is the current funding status? | Panel-upgrade work, sub-panel additions, and electrical wiring needed to support qualifying electrification projects can be eligible HEEHRA expenses for income-qualified households. CPUC reported HEEHRA funds fully reserved earlier this year, so we do not promise current availability and confirm against the CPUC HEEHRA portal at quote time. | We share the current HEEHRA funding status from the CPUC portal and adjust the incentive line items accordingly. | HEEHRA covers all panel upgrades automatically. |
| Are there TECH Clean California, CCA (Community Choice Aggregator), or utility-side incentives that apply to this panel work? | TECH Clean California is statewide for qualifying heat-pump installations; panel-upgrade work tied to a qualifying heat pump may be eligible. Many CCAs (such as MCE, SVCE, CleanPowerSF, SJCE) and IOUs run their own electrification rebates with panel-work eligibility. We confirm the program rules in writing before the quote and list each program with its reservation status. | We confirm current eligibility with each named program and document the reservation status on the quote. | All rebates are guaranteed if you sign today. |
| What is the manufacturer warranty on the new panel, breakers, and any smart-panel hardware? | We list the manufacturer warranty for the panel and main breaker (typically 10 years), branch-circuit breakers (typically 1 to 10 years), and smart-panel hardware separately. We explain what voids each. | We attach the manufacturer warranty documents with the quote. | Warranty is whatever the box says. |
| What is your labor warranty on the panel installation, and does it cover related troubleshooting? | We offer a written labor warranty (typically 1 to 5 years) covering workmanship on terminations, conduit runs, and grounding work. We explain what is covered and what is not. | We include a written labor warranty with the quote and explain the covered scope. | Our work is good, no warranty needed. |
| Based on the Article 220 result, what do you recommend as the best next action and why? | We propose a single recommended option with the load-calc rationale, list one alternative with the cost delta, and explain what would change our recommendation. We are clear about which costs are firm and which depend on the utility or AHJ. | We summarize the recommendation in writing after the site visit and load calc. | Whatever you want is fine. |
Green flags, reasonable caveats, red flags
Green flags
- Provides a phased, sequenced plan that schedules panel work and load calculations BEFORE adding heavy electric loads
- Combined Article 220 load calculation accounts for ALL future projects in scope, not just the current phase
- Single project lead coordinates HVAC, plumbing, electrical, and solar trades under one schedule
- Coordinated permits pulled across all trades through SJPermits.org, with each phase's permit fees itemized separately
- Incentive stack mapped across federal (where still active), state (HEEHRA, TECH), utility (PG&E), and SJCE EcoHome / BayREN with current reservation status
- Whole-home backup-loads list defined upfront so battery and inverter sizing reflects total simultaneous load, not single-project scope
Reasonable caveats
- Project sequencing depends on trade availability and SJPermits.org plan-review lead times
- Initial site-visit and load-calc costs may not credit toward later phase quotes
- Some rebates require completion of prior phases before later phases can apply (e.g. panel work before any SGIP RSSE-funded battery work)
- Final per-phase pricing may shift as each trade inspects the prior phase's actual install
Red flags
- Treats each project as independent with no shared Article 220 load calculation
- Quotes whole-home all-in with a single lump sum and no per-phase pricing
- Recommends solar or battery before panel-capacity verification
- Skips Manual J for HVAC sizing because the project is bundled
- Promises a §25C credit for installations after December 31, 2025
- Promises HEEHRA, SGIP, or BayREN stacking without confirming current funding and reservation status
- Skips a permit for a sub-scope because the project is bundled (each scope still requires its own SJPermits.org permits)

| California Home Electrification and Appliance Rebates (HEEHRA) — single-family | When available, up to $8,000 (households below 80% AMI) or $4,000 (80–150% AMI) for a qualifying heat pump HVAC system, with additional rebates for heat pump water heaters, electrical panel upgrades, and wiring inside the per-household envelope. Phase I single-family funds are currently fully reserved (waitlist active). | PROGRAM STATUS: Single-family Phase I is FULLY RESERVED statewide as of 2026-02-24 — new single-family applications are not being accepted and a waitlist is in place. Multifamily applications remain open. Phase II is under development pending DOE approval. HEEHRA is California's implementation of the federal IRA Home Electrification and Appliance Rebates program, administered by the California Energy Commission (CEC) with single-family implementation through TECH Clean California. When open, eligibility requires income-qualified single-family homeowners (or landlords with income-qualified tenants) at or below 150% of Area Median Income; income tiers determine rebate amount (below 80% AMI vs 80–150% AMI). Projects must obtain an approved reservation before installation; rebates only apply to heat pumps installed after the reservation is approved. Income verification is required before a contractor can submit a reservation. Replacement of an existing non-heat-pump space heating system is required for the HVAC rebate.

| TECH Clean California — heat pump HVAC incentive (single-family, market-rate) | Currently unavailable: single-family heat pump HVAC incentives are fully reserved as of 2026-05-30. Historical incentive amounts varied by utility service territory and customer income tier — verify against techcleanca.com for re-opening announcements. | PROGRAM STATUS: Single-family heat pump HVAC incentives are FULLY RESERVED as of 2025-11-14 — new single-family reservations are not being accepted. Multifamily program activity continues. TECH Clean California is a statewide CEC initiative administered by Energy Solutions under contract with Southern California Edison on behalf of California utilities under CPUC oversight, designed to accelerate adoption of clean space and water heating. When open, single-family eligibility requires the homeowner to be a customer of a participating California utility, the installation to use an enrolled TECH contractor (1,600+ contractors enrolled statewide), and the project to obtain a reservation before installation. Specific dollar amounts varied by service territory and income tier — refer to techcleanca.com for the next-funded round's amounts and any income-qualified bonus structure. Homeowners should not assume an incentive is available; verify current reservation status with techcleanca.com before signing a contract. | Yes | high | 2026-06-08 | California Energy Commission (CEC) / Energy Solutions, California Energy Commission (CEC) / Energy Solutions |

| California Net Billing Tariff (NEM 3.0) — solar export compensation framework | Policy framework, not a direct rebate. Excess solar generation exported to the grid is compensated at a rate reflecting the time-varying grid value of that generation (Avoided Cost Calculator methodology), rather than at the retail electricity rate that NEM 2.0 used. Net export compensation under the Net Billing Tariff is typically materially lower than under NEM 2.0; pairing solar with battery storage may materially affect project economics under this framework. | POLICY IN EFFECT — NOT A REBATE: The Net Billing Tariff (NBT), commonly called 'NEM 3.0,' is the current Net Energy Metering framework for new residential solar interconnections in California, adopted by CPUC Decision 22-12-056 and effective for applications submitted on or after 2023-04-15. It applies to new customer-generator interconnections in the three large investor-owned utility territories: Pacific Gas and Electric (PG&E), Southern California Edison (SCE), and San Diego Gas & Electric (SDG&E). LADWP and other publicly owned utilities operate their own net-metering tariffs and are not covered by NBT. Under NBT, onsite solar generation first offsets the customer's own consumption; excess generation exported to the grid is compensated at a time-varying export rate based on the grid's avoided cost rather than the retail rate. Existing NEM 1.0 / NEM 2.0 customers are generally grandfathered under the legacy tariff for a defined period from their original interconnection date — verify against the customer's utility for the legacy term. Homeowners considering new residential solar in PG&E / SCE / SDG&E territory should model project economics specifically under NBT, with and without paired battery storage, before signing a contract. | Interconnection application required, not a financial preapproval. | high | 2026-05-30 | California Public Utilities Commission (CPUC) |
| California Equitable Building Decarbonization (EBD) Direct Install Program | No-cost direct-install upgrades for income-qualified households — homeowner does not pay out-of-pocket for covered measures. Measures may include heat pump HVAC, heat pump water heater, induction stove, electrical panel upgrade, and weatherization, subject to a per-household scope set by the regional implementer. | Administered by the California Energy Commission (CEC) as the statewide Equitable Building Decarbonization Direct Install Program, with delivery through regional implementers and a separate Tribal Direct Install track. Targets low- and moderate-income households in low-income communities; specific AMI thresholds and per-region eligibility rules are set by the regional implementer rather than statewide. Both single-family homeowners and renters in eligible buildings may qualify, though scope and contractor selection are determined by the implementer (homeowners do not freely choose contractors). The program is funded through California IRA HOMES funding (60% allocation to Direct Install, approximately $130.3M) plus state appropriations. Direct Install retrofits began rolling out in summer 2025. Homeowners interested in EBD should contact the CEC at equitablebuildingdecarb@energy.ca.gov or watch for their regional implementer's launch announcement; the program does not accept open online applications the way TECH or HEEHRA do. | Yes | medium | 2026-05-30 | California Energy Commission (CEC), California Energy Commission (CEC) |
| Section 30C Alternative Fuel Vehicle Refueling Property Credit (residential EV charger) | Had a statutory cliff on June 30, 2026. For property placed in service Jan 1, 2023 – June 30, 2026: 30% of the cost of qualifying residential EV charging property, up to $1,000 per item (per charging port, fuel dispenser, or storage property), claimed on IRS Form 8911. Only homes located in a qualifying low-income community or non-urban census tract may have qualified. Installations placed in service after June 30, 2026 do not qualify. | §30C federal EV-charger credit had a statutory cliff on June 30, 2026 (OBBBA Public Law 119-21, 139 Stat. 72, signed July 4, 2025). Under the statute, the credit 'will not be allowed for any property placed in service after June 30, 2026.' This was a cliff termination with no transition rate — installations placed in service on July 1, 2026 or later do not qualify, regardless of when payment or contracting occurred. For property placed in service Jan 1, 2023 through June 30, 2026, the credit covered 30% of the cost of qualifying alternative fuel vehicle refueling property installed at a U.S. home used by the taxpayer as a main home, capped at $1,000 per item (the cap applied separately to each charging port, fuel dispenser, or storage property). Property had to have original use beginning with the taxpayer. Census-tract eligibility was the load-bearing constraint: per IRS guidance, the property had to be installed in a low-income community census tract or non-urban census tract — 2015 Census Tract boundaries applied to installations placed in service before Jan 1, 2025; 2020 Census Tract boundaries applied to installations placed in service on or after Jan 1, 2025. Many urban high-income census tracts did not qualify even where the homeowner installed an otherwise eligible charger. Homeowners claimed the credit on Form 8911 attached to their federal tax return. Pre-cliff installs may have qualified — verify both the placed-in-service date and the census-tract eligibility of the install address with a qualified tax preparer before relying on this credit. | Verify | high | 2026-06-08 | Internal Revenue Service, Internal Revenue Service |

Rebate Plus (income-qualified): up to $2,000 for charger installation, or up to $5,000 combined for panel upgrade plus charger installation. | As of 2026-05-30 the program is active. Applicants must be active PG&E residential electric customers (CCA customers eligible) who own or lease a qualifying battery-electric or plug-in hybrid vehicle. The Standard tier has no income test. The Rebate Plus tier may be available to households at or below 80% of county Area Median Income, or to participants in CalFresh, Medi-Cal, SSI, WIC, or similar assistance programs, or to recent Rebate Plus participants in the Pre-Owned EV Rebate program. Standard applicants must apply within 180 days of charger purchase; Rebate Plus applicants receive pre-approval with contractor selection before installation. Rebates are first-come, first-served and limited to one per eligible household. Homeowners may not combine this with the now-closed Empower EV program. | Rebate Plus tier: yes (pre-approval before contractor selection). Standard tier: no, but apply within 180 days of purchase. | high | 2026-05-30 | Pacific Gas & Electric, Pacific Gas & Electric |
