Chico (2), San Diego (2), Alpine (1), Anaheim (1), Berkeley (1).

How much does a home battery cost in California?

Installed cost depends on capacity, brand, whether it pairs with solar, and local labor rates. Get itemized quotes from at least three California installers listed here and ask about state or utility incentives, since the federal residential credit expired at the end of 2025.

Do I need solar to install a battery in California?

No. Battery-only installs are common for backup power and time-of-use savings, though pairing with solar usually improves the economics. Ask installers whether they do standalone battery projects.
