Cotuit Solar is a Cape-based solar installer working out of 29 Trinity Place in Mashpee, with a mailing address in Cotuit and a branch on Nantucket. The company says it has been putting solar on Cape Cod, Martha's Vineyard and Nantucket since 1988 and has installed over 950 systems, which would make it one of the oldest solar contractors in the region. The review record is long and unusually uniform: 172 reviews on file since 2022, a 5.0 Google average across 190 ratings, and an A+ grade at the BBB. What reviewers describe again and again is the paperwork, not just the panels - permits, the historic-district and HOA approvals, the Eversource interconnection, and the SMART incentive filings all handled by the company rather than the homeowner. The work covers rooftop and ground-mount PV, pole-barn arrays, battery storage, EV chargers and solar thermal. Reviewers in 2026 describe a 50-panel, 20,000-watt residential install, a condominium array that needed the association signed off, and a project on Martha's Vineyard; a 2025 reviewer had panels temporarily removed so a skylight leak - which turned out not to be the panels - could be traced and repaired. Service after the sale comes up repeatedly. A January 2026 reviewer whose original installer, SunRa Solar, closed down says Cotuit took the system on and replaced a failed micro-inverter; a 2023 reviewer describes an inverter replaced years after the original install. Several people mention working with the company for a decade or more, and one says almost twenty years. Worth asking about before you book: the timeline and who holds which licence. Reviewers describe permitting stretching over months (one was quoted about three months, another says the whole process took eight), which is normal for Cape solar but worth pinning down; and one reviewer notes the company was somewhat more expensive than a competing quote, choosing it for its service record. The state registry confirms home improvement contractor registration 146276 in the company's own name; the master electrician licence 22826 the company cites is registered to Jeffrey Greenwood, the electrician on its staff, not to the company itself.

Cotuit Solar was absolutely wonderful to work with from the planning process to final installation. We couldn’t be happier with our system!!
I have found Cotuit Solar to be highly professional, delivering what they promised when they promised, and providing excellent customer service for any questions, issues, help with interfacing with Eversource, etc. Every member of the staff I have encountered has been both very professional and exceptionally friendly and helpful. I recommend them highly.
Cotuit solar was amazing every step of the way. They actually finished ahead of schedule which was great. Highly recommend!
Cotuit Solar came highly recommended to us by a neighbor here on Cape Cod so we signed up to have solar panels put on our house. Matt came out and measured up the roof and designed a system. He told us it would take approximately 3 months for all the permits to be approved. Much to our surprise, all permits were completed in 2 weeks and the installation was scheduled. A 6 man crew showed up to our house the following week. Installation commenced the moment the crew got out of the truck. Everyone had a job to do and the installation was fast and clean. All trash was picked up and a half day later my system was installed. The crew was friendly, answered any questions I had and thanked me for choosing Cotuit Solar. The Town was out today to do the electrical inspection and we are scheduled with Eversource to have our meter swapped out and the system turned on. We could not be any happier as everything went as planned and we are well ahead of schedule. A big Thank you to Nikki, Matt, Jeff and last but not least the installation crew. The job looks terrific!!!
