Valley Solar
The evidence
Founded 2015 per Solar Power World, with a BBB business start of January 2015 and incorporation in January 2016. Locally owned and operated by co-owners Mike Hempstead and Patrick Rondeau. Eleven years in business, all of it in the same western Massachusetts market.

BBB rating A+, accredited since April 2022, no government actions found, and no lawsuits or distress signals surfaced in our research. BBB does not display a complaint count for this profile, so we mark the criterion pending rather than assuming a clean sheet.

Ranked #13 on the 2026 Solar Power World Top Massachusetts Solar Contractors list with 4,010.09 kW installed in 2025, and 21,875 kW since founding per its trade press supplier profile. Notably, its entire national footprint is Massachusetts, which for a buyer here is a feature, not a limitation. The company's claim of 2,800+ total systems is its own number and we treat it as a claim.
BBB lists Division of Professional Licensure license 664 expiring July 31, 2028 and HIC registration 186338 expiring October 27, 2026. Expiration dates on file are a good sign; no other installer in this set has them visible. Still BBB-reproduced rather than confirmed against a live state record, because Massachusetts offers no machine-readable lookup, so pending on a technicality.

Publishes a 95% production guarantee backed by its SunAlert monitoring program, which is a real commitment with a measurable trigger. What is missing is a workmanship warranty term in writing on any public page. Ask for the labor coverage period before you sign; the production guarantee does not cover a leaking roof penetration.

How to read this
Valley Solar sits in an unusual spot: small, local, and better documented on licensing than installers twenty times its size. If you live in the Pioneer Valley it belongs on your quote list. The open items are a visible complaint count and a written workmanship term, and the second one you can close yourself by asking. The 95% production guarantee is only as good as the monitoring behind it, so ask how SunAlert measures shortfall and what the payout mechanics are. 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.
