    Someone explain to me why I have to pay 1.5 times my national grid bill with this 4 star community solar company? What a waste of money! The way you rub people playing with their fears.

  • 1★ · around July 2026 · the company replied

    Still getting bills almost 6 months after canceling my account. Do not do business with them! This is a scam.

  • 1★ · around July 2026 · the company replied

    Billing is confusing, credits to utility so delayed the 10% Solar savings eaten up by late fees . Customer service abysmal.

  • 3★ · around August 2025 · the company replied

    It's hard to tell if I'm saving the advertised 10% because their billing operation is so screwed up. They claim this is partly because they get late and/or incorrect from National Grid. This may or may not be true, but what I see is high bills supposedly because of multiple cycles billed at once. Occasionally, they claim the problem has been fixed, but it never is. Also, and unlike virtually all companies I've encountered, they insist on saving my credit card number as a default, rather than making that an opt-in feature. I've asked them multiple times to change this. They say they'll "look in

    I like Nexamp, during the winter months in the months in the Northeast they don't really offer much help, but during the summer its pretty good. They however have not been great about rewarding for referrals. I'm still waiting on the gift card months and months later.

    Going on 2yrs with Nexamp and our electric bill has always been lower then what CMP charged (even with out the 15% savings).

  • 5★ · around August 2025 · the company replied

    I’m happy to be a part of this movement to explore better ways to receive our energy. NEXAMP IS POISED FOR THE FUTURE and I’m ready to join in with them. They seem very impressive and customer focused. RR Glens Falls,N.Y.

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.
