  Went there the first time today. Busy place, but Glenn took the time to find me a cv for my older water heater. I mean he searched everywhere and finally succeeded, then he helped me by supplying me with names of plumbers, because I don’t know how to solder, so I could get the old part disassembled and then reassembled with the new parts. The trip was a huge success! My water heater fitting no longer leaks and I can put away the mop. Also Vince provided me with insight on how to find my water heater anode and suggested I send pictures of what I have to see if it is wise to change the anode on

Reviewer names are not published here. Negative reviews are shown first because they are the ones a listing hides, not because they are more representative.

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.

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

• Years in business

  “using Inter-Island Solar Supply for over 17 years…and counting. They not only provide…”

• It is also reviewed on Yelp. Worth reading before you sign anything: those are a different crowd, and the complaints that reach the Better Business Bureau rarely reach Google.

Google’s own “people also viewed” set, in Google’s order. It is Google’s comparison, not ours.

The ones without a link have no page here, either because Google does not categorise them as solar businesses or because we could not match the name to a listing with confidence.

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.

• —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.
