California Solar Incentives: Federal, State, and Local Programs

California Solar Incentives at a Glance

California offers one of the most layered incentive landscapes in the U.S., combining a robust federal tax credit with state-level cash rebates, a property tax exclusion, and net metering rules that let homeowners export excess generation. The exact package a household receives depends on utility territory, income eligibility, and whether the system is on a primary residence or a commercial building. Below is what is currently available and what matters most for a mobile-first search.

Federal Investment Tax Credit

The federal Residential Clean Energy Credit covers 30% of the total installed cost of a solar energy system, with no cap on the credit amount. The credit applies to the solar panels, racking, wiring, and labor for installation. It is claimed on IRS Form 5695 and can be carried forward if the tax liability is smaller than the credit value. This benefit is available to California homeowners and is not means-tested.

California State Incentives

The state layer includes several programs that interact with one another:

• California Solar Initiative (CSI) / SGIP — The Self-Generation Incentive Program provides upfront cash rebates for solar PV and storage. Rebate tiers have shifted toward storage and low-income households as the program matures.
• Property Tax Exclusion — Solar energy systems added to a primary residence are excluded from the property's assessed value for property tax purposes, so adding panels does not raise annual property taxes.
• Net Energy Metering (NEM 2.0 and successor tariffs) — Rules have evolved from the original NEM program into NEM 2.0 and now into NEM 3.0 successor tariffs that credit exported kWh at a lower rate than consumption, making self-consumption and battery storage more financially attractive.

Local and Utility Incentives

Incentives vary by utility territory and municipality:

• Single-family Affordable Solar Homes (SASH) — A program in select territories, including some served by PG&E and SCE, that provides rebates specifically for low-income homeowners.
• Disadvantaged Community (DAC) rebates — Additional incentives for households located in DAC-designated census tracts.
• Municipal and county programs — Some jurisdictions offer streamlined permitting, reduced interconnection fees, or additional cash incentives.

Battery Storage Incentives

Because NEM successor tariffs reduce the value of exported energy, pairing solar with battery storage has become a strategic move. The federal ITC now applies to battery storage if it is charged exclusively by the solar array, and SGIP continues to offer rebates for storage paired with solar.

How to Claim These Incentives

Most solar installers handle the federal ITC paperwork and coordinate SGIP or SASH applications during the permitting process. Homeowners should confirm their utility's current interconnection agreement and tariff tier, as the incentive stack can shift depending on when the system is activated relative to tariff rule changes.
