Is a home battery worth it in California?
California has the highest residential rates in the contiguous US, a SGIP rebate program, and a VPP market. Under NEM 3.0, self-storage beats exporting. Here are the real 2026 numbers.

Strongest case in the US, but only for the right household.
Under NEM 3.0, exporting solar pays little, so storing it yourself is where the money is. The 30 percent federal PURCHASE credit expired Dec 31 2025, so a 2026 cash buyer gets nothing federal. SGIP and (for lease or third-party-owned systems) Section 48E are what move the math now. The honest exception: a low-usage home with no solar on a flat rate plan, where a battery mostly buys peace of mind, not payback.

California battery FAQ
Is there a federal tax credit for a home battery in California in 2026?
Not if you buy outright. The Section 25D homeowner purchase credit (the 30 percent residential ITC) terminated Dec 31 2025. A 2026 cash buyer gets zero federal purchase credit. The lease and PPA route lets a third-party owner claim the Section 48E commercial credit, which may lower your effective lease price.
What is SGIP and do I qualify?
SGIP is California's Self-Generation Incentive Program, run by the CPUC. Most PG&E, SCE, and SDG&E customers qualify for the General Market tier ($150-200/kWh rebate on usable capacity). Customers in high-fire-threat districts or on medical baseline can receive the Equity Resiliency tier, up to roughly $1,000/kWh. Funding is limited and opens in rounds: check the CPUC SGIP portal for availability.
How does NEM 3.0 affect whether a battery is worth it?
NEM 3.0 sharply reduced solar export rates for new interconnections compared to NEM 2. Exporting surplus power no longer earns you near-retail credit. A paired battery lets you store that surplus and use it yourself at full retail value instead of selling it cheaply, which is what makes the economics work for most California solar households under NEM 3.0.
What can I earn from a California VPP program?
Virtual Power Plant programs (Tesla/PG&E, SCE, SDG&E) dispatch your battery during grid stress events in exchange for annual payments. For a mainstream 10-15 kWh system, the range is roughly $400-$1,500/year depending on dispatch frequency, battery capacity, and program tier.
