Solar installer directory
2,602 installers ranked by what they've actually done: 2.9 million public installation records. Nobody pays to be listed or ranked here.
What this data can and can't tell you. Records come from LBNL's Tracking the Sun (27 states, through 2025) and California's interconnection data (through August 2026). They show volume, prices, equipment and business model, not workmanship or customer service. Always check the license, reviews, and get at least three quotes.
