    We had an amazing experience with this company from start to finish. The entire team was professional, knowledgeable, and honest throughout the process. They took the time to explain everything clearly, answered all of our questions, and helped us choose the best solution for our home and budget. The installation was quick, clean, and completed on schedule. The crew was respectful and made sure everything looked great before leaving. Since switching to solar, we’ve already noticed a significant reduction in our electric bill, and it feels great knowing we’re using clean energy. What really sto

    COREnerG From start to finish, the entire process was smooth and professional. The team was knowledgeable, transparent, and always available to answer my questions. Installation was quick, clean, and completed exactly when promised. Since going solar, I’ve already noticed major savings on my electric bill. If you’re looking for a company that actually cares about customer service and stands behind their work, I highly recommend them.

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 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.

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.
