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 and the 30% federal credit, the case for acting this year is strong.
California Solar Incentives in 2026
- Federal tax credit (30%) on the full system cost.
- Property-tax exclusion — the added home value is not taxed, but this is set to sunset Jan 1, 2027. Installing in 2026 locks it in.
- 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.
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 before incentives, less after the 30% federal credit. High rates mean fast payback.
