County Context
Merced County sits in the central San Joaquin Valley with flat agricultural terrain ideal for solar. The area experiences extreme summer heat with very high cooling demand, making solar especially valuable for offsetting AC costs. High PG&E rates throughout the county drive strong solar economics. Agricultural and rural areas benefit from solar with battery storage for energy independence and reliability.

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