FAQ
San Diego Solar FAQs
How much do solar panels cost in San Diego in 2026?

Why is San Diego one of the best cities for solar?
San Diego combines 266 sunny days per year with SDG&E's extremely high electricity rates ($0.40–$0.70/kWh on TOU plans). This means solar offsets very expensive electricity, resulting in one of the fastest payback periods in the nation — often under 5 years.
What solar incentives are available in San Diego?
San Diego homeowners benefit from the federal 30% ITC, NEM 3.0 net billing with SDG&E, SGIP battery storage rebates, California's property tax exclusion, and PACE financing options. The combination of incentives and high utility rates makes solar extremely attractive.
Should I add battery storage to my San Diego solar system?
Yes, battery storage is highly recommended in San Diego. Under NEM 3.0, export rates are lower than retail rates, so storing energy in a battery to use during SDG&E's expensive peak hours (4–9 PM) maximizes your savings significantly.
