Its one and two star share is level with the typical installer in the Plymouth area. Across Massachusetts, 107 of the 198 installers whose breakdown Google has published carry a higher share than this one.

The percentages are Google’s own arithmetic over every review it holds, not a sample we assembled. Separately we hold 190 review texts for this company, quoted below. Google publishes review ages rather than dates, so every date here is approximate.

    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.

Topics Google derives from the review text, with how often each appears. A frequent topic is not a good one: “price” turns up in praise and in complaints alike.

What the company says about itself

Taken from its own website. We have not checked any of it, and a sentence on a website is not evidence.

  • Established

    “She has been with Cotuit Solar since 2006 after a short career in furniture…”

  • Insured

    “Vineyard and Nantucket. We are fully insured and maintain all necessary state and…”

  • Licensed

    “and two daughters. Jeff Jeff is a licensed Master Electrician (license #22826 A)…”

Its website also mentions warranty, years in business and licence number, but not in a sentence we can quote cleanly.

Elsewhere

  • It posts on Instagram and Facebook. A page that stopped posting years ago tells you something a listing will not.

As Google published them when we last read the listing, not a live check. Ring before you drive anywhere.

Ordered by how much we can tell you about each, which is not an order of quality. We do not know which of these is better and would not say if we did.

What we don't know

  • The date above is the newest review we hold, which is not necessarily the newest that exists — we hold a large share of Google's reviews, not all of them.
  • We do not verify licences, insurance or bonding. Nothing here has been checked against a state licensing board.
  • We cannot tell you what an installation costs, and we hold nothing about the equipment they fit.
