    Takes too long to get a service appointment. Have had to get 3 services since installation 3 months ago because solar is not working properly!

    It is not often these days that I get pleasantly surprised but today I did. Six years ago, we purchased a solar pool heating system. I never had it serviced and it seemed to work fine. I recently got a water leak warning on my home flow meter which turned out to be a malfunctioning landscape water valve. In searching for the leak our plumber went onto the roof to check the solar pool water heating system piping and did notice a few minor leaks around the piping flanges. Also unrelated, the small system controller display had faded over the years from the sun and was difficult to read the LED d

    We couldn’t be happier with the service we received! The team was professional, knowledgeable, and efficient from start to finish. They walked us through the entire process, answered all our questions, and provided an affordable, high-quality solar solution for our pool. Now, our pool stays warm and comfortable year-round, and we’ve noticed a significant drop in our energy costs. The installation was seamless, and they left everything clean and tidy. Highly recommend this company to anyone looking to upgrade their pool heating system with solar energy!

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.

  • Warranty

    “to install. Who do I contact for the warranty on my system after it is installed?”

  • Established

    “the best quality products and service since 2001 . We are the solar & water…”

Its website also mentions free estimate and insured, but not in a sentence we can quote cleanly.

Elsewhere

  • It posts on X, LinkedIn 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.

Who Google shows alongside them

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.

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.
