Solar Rebates in San Diego, California (2026)

San Diego is one of the strongest solar markets in California — abundant sun (5.5 kWh/m²/day), high SDG&E retail rates ($0.40+/kWh peak), and full eligibility for California statewide programs (SGIP, TECH Clean California, NEM 3.0 successor). SDG&E specifically runs additional charger and battery rebates beyond the SGIP statewide program. With NEM 3.0 making battery storage essential for reasonable solar payback, San Diego homeowners typically install 7–9 kW solar paired with 13.5 kWh battery. The federal 25D credit (30% uncapped) plus SGIP General Market ($150/kWh battery) plus 25D on the battery delivers strong stacking. Income-qualified households access SGIP Equity tier ($850/kWh) or Equity Resiliency ($1,000/kWh) and DAC-SASH free solar.

San Diego-specific FAQ

SDG&E rates compared to other CA utilities? +

SDG&E has the highest residential rates in California and among the highest in the US — $0.40+/kWh peak under TOU. This makes solar self-consumption extremely valuable.

Battery essential or optional in San Diego? +

Essential under NEM 3.0. Without battery, NEM 3.0 export rates ($0.05–$0.15/kWh avoided cost) crush economics. With battery, self-consumption arbitrage at $0.40 retail sustains 7-year payback.
