    Don't ever use this company to install your solar panels. They have me signed up for TWO loans to pay off my panels because the first loan company went bankrupt and Sunergy never cancelled my first loan! I'm literally STILL trying to get a hold of someone! I was reimbursed for 4 months of double payments, but I'm STILL getting charged and NO ONE IS ANSWERING. I will never recommend this company to anyone. It seems like they are just disorganized.

    Sunergy Solutions installed a ground mount system with sunlight back up for us, ordered and signed in early 2022. There were supply chain issues for installation hardware at the time, not Sunergy‘s fault, that caused significant delays and they paid my Eversource electric bills for several months - so no harm no foul! It was commissioned in early in 2023 and has been problem free and humming along ever since. We get pretty frequent long-duration outages so the sunlight backup has been great. It came with a smallish 3T battery that got us through outages and nights with a few essential circuits

    Sunergy solutions installed our solar panels in 2024. Our consultant, Jeff Deming, was professional, knowledgeable, and responsive whenever we reached out with questions. He worked within our budget and helped find us options for financing. Installation was efficient and professional. The installers worked to ensure that the aesthetics of the house would be minimally altered by wiring, electrical boxes, etc. We had one issue where a row of panels stopped producing (unknown reason) but Jeff ensured a technician came out quickly to fix the issue. This is a great company to work with and we have

    This has been our second solar installation. The experience has been first rate all the way. Once we decided on a plan, everything went seamlessly. We have made recommendation to a number of our friends.

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

    “standards. Final Walkthrough & Warranty – We review the work with you and…”

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

  • It posts on Facebook. A page that stopped posting years ago tells you something a listing will not.

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 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.
