Its one and two star share is 29 points above the typical installer in Tennessee. Across Tennessee, 9 of the 53 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 27 review texts for this company, quoted below. Google publishes review ages rather than dates, so every date here is approximate.

    They get one star. They should really have no stars, but to leave a review They have to get 1. Sooo I read a very positive review and clearly they haven't had a problem come up, so hang in there They will screw you over eventually. I have have had NOTHING but trouble in most recent years, in fact I have gone OVER A YEAR with part of my service not working. When I called I was told by the engineer that it wasnt a big enough problem for them to come out!!! $54000 for that part of my solar and it didnt work properly and eventually quit working completely and if it was working we couldn't monitor

    Mountain Challenge and Maryville College decided to make an historic building capable of using 100% solar energy. And we asked Solar Alliance for assistance. Everyone at Solar Alliance was - and still are - amazing. From data analysis to design to construction to marketing and follow-up, they stayed with us every step of the way. And they still provide thoughtful and fast answers to on-going questions. They definitely performed above and beyond. We are grateful.

    Professional, knowledgeable, skilled, experienced, and customer-oriented; we've used their services twice before and are now again; continuing excellent and outstanding performance.

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.

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.
