VoltSol gives 4 cities across Mendocino County a way to energy independence: residential solar paired with EG4 battery storage, from $8,700. Make your own power, store it, and keep the lights on through blackouts and PSPS shutoffs — instead of exporting it back to the grid for a fraction of what you paid under NEM 3.0.
County Snapshot — Mendocino County
Utility Rate
PG&E: Estimated $0.44/kWh residential rate. PG&E serves this North Coast and inland region with rates averaging $0.44/kWh. Frequent PSPS shutoffs in wildfire zones make battery backup critical.
Permit Office
Mendocino County Planning & Building (Mendocino County). Typical turnaround: 2-4 weeks. County processes permits for coastal and inland wine-country installations. Coastal sites need marine-grade hardware. Wildfire zones require fire-resistant design and PSPS backup.

County Context
Mendocino County spans foggy North Coast (Fort Bragg, Point Arena) to hot inland wine valleys (Ukiah, Willits). Coastal areas see 4.4-4.6 peak sun hours with marine fog, while inland Ukiah Valley gets 5.0-5.2 hours with hot summers. Severe wildfire history and frequent PSPS shutoffs make battery backup essential for both coast and inland.

Why Solar + Battery Storage in Mendocino County?
Homeowners in Mendocino County are served by PG&E, which has seen significant residential rate increases in recent years. Residential solar + battery storage offers a way to lock in energy costs at installation prices and protect against future rate 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 — while maximizing the power you keep and use yourself. That means no utility buyback complexity under NEM 3.0, and backup power during PSPS shutoffs or outages.
Under California's current net-billing rules (NEM 3.0), the credit homeowners receive for solar energy they export is typically only a small fraction of the retail price they pay to buy electricity back. The smart economics in Mendocino County shifted to storing and using your own power instead of selling it back. The federal 30% residential solar tax credit ended for systems placed in service after Dec 31, 2025, but California programs like SGIP battery rebates may still apply. Consult a tax professional to confirm your eligibility.
