Local Factors
Navigating the solar installation process in Atherton requires understanding local regulations and costs. You’ll need to obtain permits from San Mateo County, which can vary slightly in requirements depending on your specific property. Expect permit costs to range from $500 to $1500. Installation labor rates in the Bay Area are generally higher than the national average, typically ranging from $75 to $125 per hour. Remember to verify your contractor’s license with the California Contractors State License Board (CSLB) before signing any agreements. With California’s Net Metering 3.0 (NEM 3.0) policy now in effect, incorporating a battery storage system, such as a Tesla Powerwall, is highly recommended to maximize your savings by storing excess solar energy for later use. Plus, adding solar panels won’t increase your property taxes in California.

FAQ
- How long does it take to install solar panels? Most residential solar panel installations in Atherton take between 1-3 days, depending on the complexity of the roof and system size.
- Will solar panels work on my roof type? Solar panels can be installed on most roof types, including asphalt shingles, tile, and metal. A professional installer can assess your roof’s suitability.
- What happens if I produce more solar energy than I use? Under California’s NEM 3.0 policy, excess energy is sent back to the grid. While NEM 3.0 reduces credits for excess energy compared to previous versions, a battery system will let you store your excess energy for later use, maximizing savings.
