    I feel completely scammed by this company. I wish I could give less than one star. I had solar panels installed, but it took nearly seven months just to get the system connected. During that time, I was still paying $200 a month on the loan—on top of my regular utility bills. When they finally told me the system was “ready to use,” it turned out it hadn’t even been properly programmed. For over a year, the panels were on my roof but weren’t actually connected to any system to utilize the power being generated. As a result, at the end of the year, my TrueUp bill with PG&E was nearly $4,000. In

    This company is a scam. They take your money, and you never hear from them again.

    One of the many companies that I wish I could give zero stars to when it comes to our solar. They went out of business due to a 'merger ' back in June without informing any of their customers. So when we had an issue with our inverter we had to find a local company that charged us $750 to fix the problem which turned out to be something simple that the Core did wrong. On top of that they lied to us about one of our batteries working to which the other company found out they had absolutely no charge. Yet I've learned that the employees and the CEO of Solgen Construction/Core Energy have been gi

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.

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.
