Solar + Battery Storage in San Bernardino County, CA
VoltSol gives 18 cities across San Bernardino 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 — San Bernardino County
Utility Rate
SCE: Estimated $0.36/kWh residential rate. Southern California Edison (SCE) serves all of San Bernardino County at ~$0.36/kWh. Inland Empire and high desert areas experience extreme heat with exceptional solar potential. Solar economics are strong throughout the county due to high rates combined with very high cooling demand.
Permit Office
San Bernardino County Building and Safety Division / Individual City Building Departments (San Bernardino County / individual cities). Typical turnaround: 2-4 weeks. San Bernardino, Fontana, Rancho Cucamonga, Ontario, and other cities have their own building departments. Unincorporated areas fall under San Bernardino County Building and Safety. High desert areas require systems designed for extreme temperature swings.
Climate Zone
Zone 10 (western Inland Empire) / Zone 14 (high desert): Zone 10: warm to hot Inland Empire climate (Rancho Cucamonga, Ontario, Fontana, Rialto) with hot summers and high cooling demand. Zone 14: high desert climate (Victorville, Hesperia, Apple Valley) with extreme heat in summer, cold winters, and exceptional sun exposure. Excellent solar production throughout the county.
County Context
San Bernardino County spans from the western Inland Empire (Rancho Cucamonga, Ontario) through the San Bernardino Valley to the high desert (Victorville, Hesperia). Western areas experience hot Inland Empire summers with high cooling demand. Desert cities see extreme summer heat (100F+) with exceptional solar potential and temperature swings requiring robust system design. High SCE rates throughout the county drive strong solar economics.

Why Solar + Battery Storage in San Bernardino County?
Homeowners in San Bernardino County are served by SCE, 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 San Bernardino 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.
