    I can't say enough about YMGI. Last June 2024 I purchased from them a 3 ton mini split. It runs on 240AC and also 4 solar panels which add to the electrical needs to lower the electric usage. During the summer o 2024 the unit would shut down on occasion and required a 240AC disconnect for a few minutes to do a reboot and get it up and running again.

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 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.
