Solar Rebates in California (2026)

California homeowners installing solar in 2026 stack the federal 25D credit (30% uncapped) with the state SGIP battery rebate (when paired with storage) and net energy metering NEM 3.0 export compensation. SGIP delivers the highest-value state-level adder — $150 to $1,000 per kWh of battery storage depending on equity tier — and pairs well with new solar installs because batteries shift export-side economics dramatically under NEM 3.0. The PUC closed NEM 2.0 to new applicants in April 2023; new installs export at avoided-cost-calculator rates that average $0.05–$0.15 per kWh, compared to $0.30+ for retail-rate NEM 2.0. Battery storage is no longer optional in California — it is the difference between a 6-year and an 11-year payback.

Eligibility quick check

Do I need a battery to qualify for solar incentives in California?

No — but NEM 3.0 export economics make batteries essentially required for reasonable payback. The federal 25D credit applies to solar without storage, and SGIP only kicks in when you add storage.

Am I eligible for SGIP Equity tier?

You qualify for the Equity tier (much higher rebate) if your household income is at or below 80% Area Median Income, you live in a Disadvantaged Community (DAC) census tract, or you participate in CARE/FERA utility programs.

Do tribal lands have separate California programs?

Yes. The DAC-SASH program prioritizes tribal communities, and SGIP includes a tribal allocation.

Does NEM 3.0 apply if I added solar before April 2023?

No. NEM 2.0 grandfathers existing customers for 20 years from interconnection date.

How to stack with the federal credit

California programs combine with the federal 25D 25D Credit (30% of cost, no cap) — see the 25D guide for filing instructions and forms.

Worked stacking example

A $25,000 8 kW solar + 13.5 kWh battery system in San Francisco: $25,000 × 30% federal 25D = $7,500 credit. SGIP General Market ~$2,025. Net cost ~$15,475. Add $5/W upfront if Equity tier qualified.

Frequently asked questions

Does California state solar rebate stack with federal 30D EV credit? +

They are unrelated — 30D is the EV credit, not solar. But yes, you can claim 25D for solar plus 30D for an EV plus 30C for a home charger plus state EV rebate (Clean Vehicle Rebate Project) all in the same tax year.

Are there income limits on California solar incentives? +

No income limit on federal 25D. SGIP General Market has no income limit. SGIP Equity tier requires ≤80% AMI or DAC residency. DAC-SASH targets ≤80% AMI.

How much does SGIP pay for a Tesla Powerwall in 2026? +

Powerwall 3 has 13.5 kWh of usable capacity. General Market tier pays roughly $2,025 ($150 × 13.5). Equity tier pays roughly $11,475 ($850 × 13.5). Equity Resiliency for medical baseline / wildfire zones can pay up to $13,500 per Powerwall.

Can I claim the state property-tax exclusion? +

Automatically. Solar additions are excluded from property tax assessment through 2027 in California — your assessor cannot raise your assessed value because you added solar.

PG&E vs SCE vs SDG&E — does utility matter for incentives? +

NEM 3.0 and SGIP rules are statewide. Utility-specific differences are mostly in interconnection timelines (PG&E typically slowest) and avoided-cost export rates.

Is community solar in California different from rooftop? +

Community solar shares (off-site) do NOT qualify for federal 25D or California SGIP — those are owner-installed only. Community solar pays via subscription credits.

How does TOU billing affect solar value? +

Time-of-use rates make solar generation worth more during 4–9pm peak. NEM 3.0 export rates also follow TOU — afternoon export pays a fraction of evening retail. Battery shifts solar from low-value 1pm export to high-value 7pm self-consumption.

Can I claim SGIP if I install batteries without solar? +

Yes. Standalone batteries qualify for SGIP. They also qualify for federal 25D since 2023 (3 kWh+ minimum).

What about the California EV solar bonus? +

No specific bonus, but pairing solar + EV charging unlocks PG&E EV2-A residential rate plan with extremely low overnight rates ($0.27/kWh midnight) — effectively powering your EV at solar wholesale cost.

Are roof replacements covered? +

No, generally — but structural reinforcement directly required for solar mounting may be includable in the federal 25D basis. Standard re-roofing is not credit-eligible.
