Residential Solar & Battery Storage in California
VoltSol specializes in residential solar with EG4 battery storage across California — systems from $8,700. Make your own power, store it, and run your home through blackouts and PSPS shutoffs. Real energy independence, built for the NEM 3.0 era — keep the power you make instead of exporting it for a fraction of what you paid.
Why Solar + Battery Storage in California?
Sidestep NEM 3.0
California's NEM 3.0 slashed solar export credits. Battery-first systems sidestep this entirely — you store and use your own power, no utility buyback needed.
Own It, Don't Rent It
The big installers sell you a grid-tied system that still leaves you on the utility's meter. VoltSol builds you your own power plant — solar + EG4 battery — so you stop renting power from the grid for good.
Blackout Resilience
California's wildfire-driven PSPS shutoffs leave thousands in the dark each year. Solar + battery storage systems keep your lights and HVAC running.
Beat Rising Rates
Utility rates keep climbing. When you make and store your own power, your local utility's next rate hike stops being your problem — your energy cost is locked in at install.
