The 10 Best Solar Installers in San Francisco (2026)
This list ranks the top solar installers serving the Bay Area based on Google review data, updated for 2026. We use a Bayesian-style score that balances average rating with the number of reviews so firms with few perfect ratings don’t automatically outrank larger, well-reviewed shops. San Francisco homeowners face a dense urban market, varied roof types and local permitting quirks, so review-backed reputation and experience with local rules matter. The companies below are ordered strictly by that review-weighted score to help you start your search with a shortlist grounded in public feedback.
This ranking is computed from Google reviews (our method). Listings marked Partner are paid advertising spots: they sit alongside the ranking without changing its order.
