What reviewers said

  • 5★ · around August 2026

    Great communication with the sales Mike and Keith and the installation is done perfect.

  • 5★ · around August 2026

    Keith, Dean, and the electricians were all wonderful. They were thorough, patient, attentive - the work was top-notch and the installation only took a couple of days, and we had more than 30 panels installed. We’ve already started referring this team to friends.

    Just Amazing!!! Super professional and amazing service

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.

What the company says about itself

Taken from its own website. We have not checked any of it, and a sentence on a website is not evidence.

  • Warranty

    “Guarantee We offer a 10-25 year warranty on all solar equipment, workmanship,…”

Its website also mentions free estimate, but not in a sentence we can quote cleanly.

Elsewhere

  • It is also reviewed on the Better Business Bureau. 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.
  • Google publishes no street address for this company, so we cannot say which town it is based in. Eastvale is the area its listing was returned for, not an address we hold.
  • 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.
