County Snapshot — Marin County
Utility Rate
PG&E: Estimated $0.44/kWh residential rate. PG&E residential blended rate (E-TOU-C tier, 2025-2026 range). High rates make solar economics strong despite marine layer influence in many areas.
Permit Office
Marin County Community Development Agency / Individual City Building Departments (Marin County / individual cities). Typical turnaround: 2-4 weeks. San Rafael, Novato, and other cities have their own building departments. Unincorporated areas fall under Marin County CDA. Coastal and hillside areas may require additional review for fire zones or terrain.
Climate Zone
Zone 3: Mild marine climate throughout the county. Coastal and bayside areas experience frequent marine layer, while inland valleys (Novato, San Rafael) see more sun. Moderate temperatures year-round with low cooling demand but reliable solar production.
County Context
Marin County spans from the San Francisco Bay shoreline (San Rafael, Mill Valley) to the Pacific coast, with inland valleys (Novato) in between. Marine layer influence is common, especially near the coast, but solar production remains viable. High PG&E rates throughout the county make solar economics strong despite lower cooling demand. Many affluent neighborhoods value energy independence and environmental benefits.
Why Solar in Marin County?
Homeowners in Marin County are served by PG&E, 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 Marin County are stronger than ever. Consult a tax professional to confirm your specific eligibility.
