    They are out of business. They finished the install, collected money, then disappeared, leaving us to deal with PTO.

    Save a Lot Solar upgraded our inverters in January 2024 to Iq8 inverters. This required a new controller that was not included in the estimate an cost us an addition $2000. This was not appreciated because we thought that we were buying a package that included all the necessary parts. This was only the beginning of the problems. After months Save A Lot Solar was not able to fix the communication errors and eventual shutdown is the system. After quite a few months we took the issue in our own hands because of the lack of support from Save A Lot solar. Finally after working directly with Enphase

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.

  • 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.

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.
  • The website on this company's Google listing does not resolve to a working page, so we do not link it.
  • 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.
