** The home solar market in Cotati and the broader Sonoma County is **mature, competitive, and of high average quality**. Driven by high electricity rates from PG&E, strong environmental consciousness, and excellent solar insolation, the region is a hub for solar adoption. Competition is robust, which benefits consumers through competitive pricing and a focus on service quality. **Typical Pricing:** For a standard residential system (6kW - 8kW), gross costs typically range from **$18,000 to $30,000+** before the 30% federal Investment Tax Credit (ITC). The final price is highly dependent on system size, panel quality, and the inclusion of battery storage (which can add $10,000 - $20,000+). Most reputable companies offer $0-down financing options, and PACE financing (like HERO) is also available in the area, though it requires careful consideration. **Competition Level:** High.

Get answers to common questions about home solar services in Cotati, California.
For a typical Cotati home, a 6kW solar system currently costs between $18,000 and $25,000 before incentives. Beyond the 30% federal Investment Tax Credit (ITC), Cotati homeowners can benefit from California's Net Energy Metering (NEM 3.0) program and the property tax exclusion for solar installations. Additionally, Sonoma Clean Power, our local electricity provider, often offers special rebates or financing options, so checking their website for current promotions is highly recommended.
Cotati's Mediterranean climate, with over 260 sunny days per year, is excellent for solar energy production. While summer offers the most direct sunlight and peak production, our mild winters with minimal heavy fog (compared to coastal areas) still allow for significant generation. The main seasonal consideration is the angle of the sun; a properly designed system will account for this to maximize annual output, not just summer peaks.
Prioritize installers with extensive local experience in Sonoma County. They will be familiar with Cotati's specific permitting process through the City's Community Development Department, local utility (PG&E) interconnection requirements, and optimal system designs for our microclimate. Always verify they are a California Contractors State License Board (CSLB) licensed solar contractor (C-46 or C-10) and check reviews for their work on homes with similar roof types (e.g., composite shingle, tile) common in our area.
From contract to activation, the process typically takes 3 to 5 months. This timeline includes system design, securing permits from the City of Cotati, the PG&E interconnection application, the physical installation (1-3 days), and finally the city and PG&E inspections. Delays can occur during the permitting and PG&E review stages, so working with an installer who has an established relationship with local authorities helps streamline the process.
It's crucial to understand that a standard grid-tied solar system will automatically shut off during a PG&E power outage, including a PSPS event, for safety reasons. To have power during an outage, you must pair your solar panels with a dedicated battery storage system, like a Tesla Powerwall or similar. This is a significant consideration for many Cotati homeowners, and a reputable local installer can design a solar-plus-storage system to provide essential backup power.
