Why Solar in Mono County?
Homeowners in Mono County are served by Liberty Utilities / 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 Mono County are stronger than ever. Consult a tax professional to confirm your specific eligibility.
