San DiegoSolar Incentives 2026: Rebates, Tax Credits & Net Metering
San Diego homeowners stack the 30% federal tax credit and SDG&E net metering. At 5.7 peak sun hours a day, a home with a $175/month bill (about 1,250 kWh) needs roughly a 9.1 kW system — 23 panels — and pays back in about 8.4 years.
Solar Incentives Available in San Diego
Solar incentives in San Diego come in three layers. First, every homeowner qualifies for the 30% federal Residential Clean Energy Credit on the full installed cost, claimed on IRS Form 5695. California does not add a state income tax credit, so the federal credit is the main up-front incentive. Third, SDG&E sets the local rules for crediting the solar power you export.
SDG&E has some of the highest electricity rates in the country, which makes solar payback in San Diego unusually fast.
