California solar incentives

Federal ITC — 30%

All US homeowners qualify for the 30% federal Investment Tax Credit through 2032. On a $21,000 system, that's a $6,300 dollar-for-dollar tax credit.

California state programs

California's Self-Generation Incentive Program (SGIP) offers rebates for battery storage paired with solar. Under NEM 3.0 (2023), export rates changed significantly — homeowners now earn lower credits for grid exports but can benefit greatly from pairing solar with storage. The CPUC also offers income-qualified TECH Clean California rebates.
