County Snapshot — San Francisco County
Utility Rate
PG&E: Estimated $0.44/kWh residential rate. PG&E serves all of San Francisco with residential rates averaging $0.44/kWh, among the highest in California. While the city's foggy coastal climate and dense urban environment present solar challenges, high utility costs and strong environmental values make solar viable for suitable properties.
Permit Office
San Francisco Department of Building Inspection (City and County of San Francisco). Typical turnaround: 3-5 weeks. San Francisco processes solar permits through the Department of Building Inspection with typical 3-5 week turnaround. The city has strict building codes and seismic requirements. SolarAPP+ is available for eligible systems to expedite approval.
Climate Zone
Zone 3 (Coastal): San Francisco has a unique foggy coastal microclimate with cool summers, mild winters, and persistent marine layer influence. The city experiences lower solar production than inland areas, but south-facing rooftops and properties in sunnier neighborhoods like the Mission and Noe Valley still achieve viable solar output.
County Context
San Francisco is a dense urban city and county with iconic foggy coastal climate and limited single-family housing stock. Many residents live in condos or multi-unit buildings where rooftop solar may require HOA approval or shared systems. However, single-family homes with south-facing roofs in sunnier neighborhoods can achieve solid solar production. High PG&E rates, strong environmental values, and renewable energy mandates make solar attractive where physically viable.
Why Solar in San Francisco County?
Homeowners in San Francisco County are served by PG&E, which has seen significant residential rate increases in recent years. Off-grid solar offers a way to lock in energy costs at installation prices and protect against future hikes.
Our systems combine rooftop solar panels, EG4 battery storage, and inverters to power your home’s most energy-intensive loads — like heating, cooling, and major appliances — without relying on the grid. That means no utility buyback complexity under NEM 3.0, and backup power during PSPS shutoffs or outages.
With the 30% federal solar Investment Tax Credit (ITC) still available, the economics of solar in San Francisco County are stronger than ever. Consult a tax professional to confirm your specific eligibility.
