Solar + Battery Storage in Stanislaus County, CA
VoltSol gives 5 cities across Stanislaus 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 — Stanislaus County
Utility Rate
PG&E / Modesto Irrigation District (MID): Estimated $0.19/kWh residential rate. Modesto is served by MID (Modesto Irrigation District), a public utility with rates around $0.18-0.20/kWh -- much lower than PG&E. Other cities (Turlock, Ceres, Oakdale, Riverbank) are served by PG&E at ~$0.44/kWh. For MID areas, solar value comes from backup power and energy independence rather than pure rate savings. For PG&E areas, solar economics are very strong.
Permit Office

Modesto, Turlock, Ceres, and other cities have their own building departments. Unincorporated areas fall under Stanislaus County Planning and Community Development.

County Context
Stanislaus County sits in the heart of the Central Valley with flat agricultural terrain ideal for solar. The area experiences extreme summer heat with very high cooling demand. Modesto is served by MID, a public irrigation district with lower rates than PG&E, so solar value there comes from backup power and energy independence. Other cities are served by PG&E with high rates that drive strong solar economics.

Why Solar + Battery Storage in Stanislaus County?
Homeowners in Stanislaus County are served by Modesto Irrigation District / 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 Stanislaus 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.
