Complaints and enforcementVerified

BBB rating A-, not BBB accredited, 5 complaints on file, no government actions listed. For a 65 employee installer with thousands of projects, 5 complaints is a low number. The A- rather than A+ reflects those complaints.

How to read this

A provisional B means the verified record is clean and the track record is real, but two things a buyer should demand, license numbers and written warranty terms, are not publicly documented yet. That is common in this industry and it is still a gap. Our full rubric, including how our own installation business gets graded on the same scale, is on the methodology page. We are a solar installer and we partner with other solar companies. Grading is structurally separated from revenue; see disclosures.
