    Marks crew was left three crates of trash. Had to call and complain for months. System was installed July last year and the trench still is not fixed. I have more power outages than anyone on my street. This company will not fix mistakes. Then they sold my contract and no one informed me. Found out when a company i have never heard of took a payment 3 times more than what is in my contract.

    Very professional and well developed concept on solar energy technology fully customized to our home. John and Colby were exceptional at their jobs. After losing the tax credit we decided not to pursue the project, but we would not have considered anyone else for this project. Having a local company that is reliable and experienced meant very much to us.

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.

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 found nothing on a website for this company that states a warranty, a licence or how long it has traded.
  • 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.
