Where Our Data Comes From — And What We Don't Check
Most directories never tell you how their listings were assembled. Here is exactly how ours were, so you know what this page can and cannot tell you.
01 Source
Public Installation Records
Utilities and state agencies record the solar systems connected to the grid, and in many states those records name the company that installed each one. 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.
02 Ranking
Installations in the Last Three Years
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.
03 What We Don't Measure
Workmanship and Service
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.
