A solar system outlives the company that sold it.

Every listing shows you an average rating, which is the one number an installer would choose. We show the two it would not: what share of its reviewers gave one or two stars, and how long it has been since anyone reviewed it at all.

Is 2% a lot?

That is the middle of the whole US market, and nobody can tell it to you from one listing — which is why nobody asks. Read against every company we hold the question answers itself, and read against the ones in your own town it becomes useful.

Companies listed, and the median share of 1–2★ reviews among those Google has published a breakdown for.

Why the numbers here are worth reading

Nobody pays to be here: No company applied, and none can pay to appear, move up, or look better. The list is whatever Google categorises as a solar business.
Nothing can be bought off: We sell no leads and run no ads, so no number here answers to anyone it describes. An owner can claim a listing; claiming changes nothing about the figures, and every email we send them says so.
The first number is the worst one: Every page leads with the share of one and two star reviews — the figure a listing buries under its average — and prints the market median beside it, so the number means something.
