How to choose a solar installer in California
- Get at least three quotes and compare price per watt.
- Ask who owns the system: a purchase, loan, lease or PPA changes everything.
- Ask about the roof's condition and the warranty on roof penetrations.
Check the license: Contractors State License Board (CSLB). In California, most home improvement work above the state's small-job limit requires a CSLB license. Look the number up before you sign, and check that it is active and bonded.
