Why Solar + Battery Storage in Fairfield?
- ●High sun exposure: Fairfield averages an estimated 5.2 peak sun hours per day — strong solar production potential year-round.
- ●High local utility rates: PG&E customers in Fairfield pay an estimated $0.44/kWh, making solar self-consumption economics strong. PG&E residential blended rate (E-TOU-C tier, 2025-2026 range). High rates make solar economics very strong, especially for inland areas (Fairfield, Vacaville) with high cooling demand.
- ●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 Fairfield 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.
