Solar + Battery Storage in Humboldt County, CA
VoltSol gives 4 cities across Humboldt 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 Context
Humboldt County is a remote North Coast region anchored by Eureka and Arcata. Persistent coastal fog and redwood forests create lower solar irradiance than inland California, averaging 4.3-4.4 peak sun hours daily. PG&E's high rates still make solar viable, but proper system sizing is critical. Battery backup provides value during winter storms and PSPS events.

Why Solar + Battery Storage in Humboldt County?
Homeowners in Humboldt 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 Humboldt 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.
