Its one and two star share is 43 points above the typical installer in the San Marcos area. Across Texas, 36 of the 728 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 145 review texts for this company, quoted below. Google publishes review ages rather than dates, so every date here is approximate.

    Very disappointed. This used to be a great solar company! I have equipment under warranty still. Now they've changed all their phone numbers and emails and run off when I really needed them. Apparently, they never pulled the right structural permit and I'm just now finding out.

    Had them install solar on my house in 2020 and 2021, they have never cleaned or serviced them. The Telsa 2 powerwall was shutdown due to recall by Telsa and they wanted to charge me to replace under warranty/recall the powerwall2 . I having to contact a legit solar company to do the recall. There not even Telsa certified and phone number don't work but yet goodleap was able to get a hold of them. Sound fishy??

    Don't use them!!! They don't honor their warranty! My system doesn't work and since several months they are telling us that we are on the waiting list! They didn't reply to complaints with the BBB.

    This company started with good quick responses before the sale. Then continued to be somewhat responsive with the cleaning of the panels. They will not even answer their phones unless you call asking for a quote. I’m nearing the end of my warranty and have been waiting to have the panels cleaned for over four months

    Very professional and easy to do business with, definitely recommend!

    Christina was very personable and knowledgeable, and we set an appointment for the panels to be cleaned after checking their functionality.

    I really appreciate both Tina and Lauten and their assistance in updating and troubleshooting my inverter.

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 is also reviewed on Yelp and Trustpilot. Worth reading before you sign anything: those are a different crowd, and the complaints that reach the Better Business Bureau rarely reach Google.

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 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.
