How we rank installers in Berkeley
Companies headquartered in Berkeley are listed first, ordered by the number of installations we have on record for them, then by customer rating. The remaining slots go to the nearest companies within 15 miles, closest first. Paid installer memberships do not affect the order.
The installation records come from public utility and state solar program filings and from quotes homeowners upload to AgentSolar. We match each record to the installer named on it, so a company's count reflects work we can actually attribute to them, not a claim on their website.
