Most established Tempe solar contractors

Longest-licensed firms based in Tempe that hold the right ROC class, oldest license first.

How this ranking works

Organic results require an active ROC license, the correct class for the trade as the firm's primary or tied fit (a mechanical company that also holds an electrical license does not lead the electrician list), and at least one city building record here. The city does not label job type by trade, so volume is all of the firm's jobs here. They are ranked by the number of relevant jobs, then by how recently the firm worked, then by a clean disciplinary record, then by how long the firm has been licensed. This reflects license standing and real city building records - it is not a workmanship guarantee. Promoted entries, when present, are paid placements and are not scored by these rules.

Confidence: medium. The license class matches this trade; the city does not label job type, so volume is all of the firm's jobs here.
