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.

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 in San Bernardino County?
Homeowners in San Bernardino County are served by SCE, which has seen significant residential rate increases in recent years. Off-grid solar offers a way to lock in energy costs at installation prices and protect against future 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 — without relying on the grid. That means no utility buyback complexity under NEM 3.0, and backup power during PSPS shutoffs or outages.
With the 30% federal solar Investment Tax Credit (ITC) still available, the economics of solar in San Bernardino County are stronger than ever. Consult a tax professional to confirm your specific eligibility.
