Solar in San Francisco: What Homeowners Should Know
San Francisco sees an average of 5 peak sun hours per day, which is what ultimately determines how much electricity a rooftop system produces here. A standard 8 kW system (about 20 panels) generates roughly 11,680 kWh each year in San Francisco — and paired with California's local electricity rate of $0.245/kWh, that's where the savings come from.
At those numbers, a San Francisco homeowner saves about $238/month ($2,862/year). Against a $25,600 system cost (about $23,600 after California state incentives), that works out to a payback of about 8.2 years, after which the system produces essentially free power for two decades — an estimated $74,146 in lifetime savings. Note: the 30% federal tax credit expired at the end of 2025 for purchased systems, though a solar lease or PPA can still pass it through. The local grid is served by Pacific Gas & Electric, whose net metering policy directly affects how much credit you earn for surplus power.

Choosing a Solar Installer in San Francisco
- 1.Get at least 3 quotes. Prices in California vary widely between installers — comparing bids on the same 8 kW system is the fastest way to avoid overpaying.
- 2.Confirm Pacific Gas & Electric interconnection experience. An installer who regularly files with your local utility will move your permit and net-metering paperwork through faster.
- 3.Check licensing & the warranty. Look for NABCEP-certified installers and a workmanship warranty of 10+ years on top of the standard 25-year panel warranty.
- 4.Size for your actual usage. With 5 sun hours/day in San Francisco, make sure the proposed system matches your kWh history — not just your roof space.
