Why Solar + Battery Storage in San Francisco?
- ●High sun exposure: San Francisco averages an estimated 4.9 peak sun hours per day — strong solar production potential year-round.
- ●High local utility rates: PG&E customers in San Francisco pay an estimated $0.44/kWh, making solar self-consumption economics strong. 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.
- ●Battery-first economics under NEM 3.0: Under California's current net-billing rules, many homeowners now receive only a fraction of the retail rate for power they export to the grid — so the value is now in storing and using your own power — exactly what a VoltSol solar + battery system delivers. The federal 30% residential solar tax credit ended for systems placed in service after Dec 31, 2025; ask about current state programs like SGIP battery rebates. Consult a tax professional for your situation.
- ●Home value: Studies suggest homes with owned solar systems sell for more than comparable homes without — though results vary by market.
When the grid goes down, your lights stay on
Public Safety Power Shutoffs (PSPS) and wildfire-season outages can leave San Francisco homes dark for hours — sometimes days. A VoltSol solar + battery system keeps your fridge, lights, and Wi-Fi running while the grid is down. No generator, no fuel runs, no scramble.
