    Horrible customer service bought a complete system 3 months ago 3 months later still getting the runaround systems messed up you get called dumb instead of fixing it like hey I'm sorry you're having a problem let me correct this got you new ones in route again 3 months later still getting the runaround "we're waiting on the sun to test your panels" 🤔 they don't care about you I highly recommend finding a more reputable company...they're not even going to give me all my money back yeah this is a horrible company really bad customer service...

    My assistant ordered a battery for our solar panels, the battery only held a charge for 4 months. When we contacted the company they were asking us to jump through a ton of hoops to get a replacement. So much for a year warranty!! Do not waste your time with this company.

    The management is chaotic, the staff is undisciplined, and it gives the impression that they'll quit after two days! 😂 …

    I think these folks are trying to do what is being squashed by so many bigger businesses... Because they are actually competitive and help me straighten out my own install hiccups! Can we get more fair biz like this please? Thanks.

    Customer service is the best I have had from any business in some time, had to talk and text several times over a week with meter readings and different options to try, but constant communication from California to Florida with a Teck named Sohl could not have been better, I never failed to get and answer or reply back with a plan, I will buy from these folks again without giving it a thought, Thanks again for your help and patience.

Reviewer names are not published here. Negative reviews are shown first because they are the ones a listing hides, not because they are more representative.

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.

Elsewhere

  • It posts on Instagram 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 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.

Something wrong here? Tell us and a person will read it.
