We counted 1,203,790 home solar systems in utility and state records to rank the installers in 129 cities — with local prices and how often each company leases.
The states where public records name the installer of each home system are highlighted. Pick one to see the best solar companies in each city we rank:

See the top solar companies in your city, ranked by the home systems they installed, and what homeowners there paid, all from public records.
When panels stop generating or an inverter flashes an error code, every sunny hour costs money. Find repair contractors in your area and learn what the error codes mean before you call.
What solar really costs, which companies and brands lead the market, what changed with federal tax credits in 2026, and what to do when something breaks.
Market Data Qcells panels went on 26% of U.S. home solar systems installed in 2021–2023. Market share, median price and leasing for every major panel brand, from public records.

Utilities and state agencies record every solar system connected to the grid, including the company that installed it. Berkeley Lab compiles those records in Tracking the Sun, and most of our rankings are built from it. Where they don't name the installer, we use the city's own building permits. No company pays to appear or to rank higher.
Installers are ranked by the home systems they installed (or the solar permits they pulled) in each city in the three most recent years of records. Companies confirmed as closed or bankrupt are removed from the rankings and listed separately, with the news report that confirms it.
A high installation count shows local experience, not quality. We don't rate workmanship or customer service. Before hiring, confirm the license with your state contractor board, read recent reviews and compare at least three written quotes.
