California solar incentives in 2026, in one line: there is no federal tax credit for a system you buy, but the state property-tax exclusion still protects any system completed before 1 January 2027 – so 2026 is the last year to lock it in. Last updated: 16 October 2026.
California Solar Incentives 2026 at a Glance
| Incentive | Status in 2026 | What it is worth |
|---|---|---|
| Federal residential credit (Section 25D) | Ended 31 Dec 2025 | $0 on a 2026 cash or loan purchase |
| Federal Section 48E (lease / PPA) | Claimed by the system owner, not you | Indirect – may show up as a lower lease or PPA rate; tightens after 2027 |
| Solar property-tax exclusion (Rev. & Tax. Code Section 73) | Active for systems completed before 1 Jan 2027 | The value solar adds is not reassessed until the home changes ownership |
| Net Billing Tariff (“NEM 3.0”) – PG&E, SCE, SDG&E | Active | Exports credited well below retail; savings come mostly from power you use yourself – batteries help |
| SGIP battery rebate | General-market funds largely reserved; equity tiers waitlisted | Check current availability before counting on it |
| Municipal utility programs (e.g. SMUD, Riverside) | Varies by city | Some pay battery rebates or bill credits |
| Demand Side Grid Support (DSGS) and other VPPs | Active | Pays enrolled battery owners for supporting the grid during peak events |
| State solar income tax credit | None | California does not offer one |
California is the biggest solar market in the country, and 2026 carries a time-sensitive twist: the state’s solar property-tax exclusion is set to sunset on January 1, 2027, making 2026 the last “safe” year to lock it in. Combined with high electricity rates, the case for acting this year is strong.
California Solar Incentives in 2026
- No federal tax credit on a 2026 cash or loan purchase - Section 25D expired 31 December 2025. See solar tax credit 2026.
- Property-tax exclusion - the added home value is not taxed for systems completed before 1 January 2027. Installing in 2026 locks it in until the home changes ownership.
- High electricity rates - among the highest in the U.S., so every kWh you offset saves more.
- Net billing (NEM 3.0) - pairing with a battery improves the economics under current rules.
- Local and utility programs, especially for batteries and grid-support (VPP) payments.
Why a Battery Matters More in California
Under California's current net-billing rules, adding a home battery significantly improves your savings because you store your own solar power instead of selling it back at a low rate. Many California buyers now pair solar with storage.
What Solar Costs in California
A typical 7 kW system runs about $21,000 installed, with no federal credit to reduce it in 2026. California's high electricity rates still mean relatively fast payback.

California Solar Incentives FAQ
What solar incentives are available in California in 2026?
The main ones are the solar property-tax exclusion (for systems completed before 1 January 2027), net billing with your utility, battery and grid-support payments from some utilities and the DSGS program, and whatever remains of SGIP battery funding. There is no federal credit for a system you buy, and California has no state solar income tax credit.
What is changing in California in 2027?
The solar property-tax exclusion is scheduled to sunset on 1 January 2027. Systems completed before then keep the exclusion until the property changes ownership; systems completed later may be assessed as taxable new construction. An extension has been proposed but not enacted as of October 2026.
Is there a California state solar tax credit?
No. California does not offer a state income tax credit for residential solar. Its incentives come through property-tax treatment, utility programs and battery rebates.
Is SGIP still available in 2026?
Barely. Most general-market SGIP battery funding has been reserved, and new applications are largely limited to equity and resiliency tiers with waitlists. Ask your installer to confirm current funding in your utility territory before you count it in the price.
Is solar still worth it in California under NEM 3.0?
Often yes, because California electricity rates are so high - but the savings now come mostly from power you use yourself, not from exports. That is why a battery, or shifting usage into daytime, matters more than it did under NEM 2.0. See solar panel cost in California.
Do I need a battery in California?
Not required, but under current net-billing rules a battery noticeably improves savings, which is why many California homeowners add one.
Can I still get a federal credit with a solar lease in California?
Not directly. The leasing or PPA company can claim Section 48E and may pass some of it on as a lower rate. Read the escalator and term carefully. More: what happened to the solar tax credit in 2026.
