Self-Generation Incentive Program (SGIP)

The Self-Generation Incentive Program (SGIP) pays out as a direct rebate rather than a tax credit, one of California's solar incentive programs tracked in DSIRE. Eligibility is scoped to residential customers, with a stated benefit of $0.25-$0.85/Wh for battery storage. DSIRE lists no scheduled sunset, though enabling legislation and appropriations can still be revised year to year.

That's the backdrop this incentive works against. California averages 5.8 kWh/m²/day of usable sunlight and residential rates of 30¢/kWh, producing an estimated 10,162 kWh/year and $3,049 of annual utility offset on a typical 6 kW system costing $19,200. That baseline already implies a 6.3-year simple payback and a 25-year modeled net of roughly $57,025 before this incentive - every dollar this rebate delivers compresses that payback further.

A handful of other levers are worth checking alongside this one. California has 5 solar incentive programs indexed in DSIRE, including adjacent options like CA Active Solar Energy System Property Tax Exclusion, California NEM 3.0 (NBT), CA Green Tariff/Enhanced Community Renewables. The state's net-metering policy is classified as partial, which governs how excess generation is credited and often decides whether a given program is worth claiming for a specific household.
