Local Factors
Navigating the permit process in San Francisco can add time to your solar installation. Expect to file for permits with the Department of Building Inspection. Your chosen solar installer should be well-versed in local requirements to ensure a smooth process. Labor rates for qualified solar installers in San Francisco are generally higher than the national average due to the cost of living and demand. When selecting a contractor, be sure to verify their license at California Contractors State License Board (CSLB) to guarantee they are properly licensed and insured. Also, keep in mind that California law mandates solar panel installation for most new homes (Title 24).
Weather Impact
West Portal benefits from abundant sunshine, averaging over 260 sunny days per year. This makes it an excellent location for solar panel installation, maximizing your system’s energy harvest. The consistent sunshine translates to higher energy production throughout the year. Because of California’s Net Energy Metering (NEM) 3.0 policy, adding a battery system, such as a Tesla Powerwall, becomes extremely important. NEM 3.0 significantly reduces the credit homeowners receive for excess energy sent back to the grid. By storing excess solar energy in a battery, you can use it later when solar production is low, increasing your self-consumption and maximizing your savings. Adding solar panels will NOT increase the homeowner’s property taxes in California.
