Harmony Energy Works Incorporated

Each mark is one company we hold in New Hampshire whose Google breakdown has been read, placed by its share of one and two star reviews. Harmony Energy Works Incorporated is the red one. The amber line is the middle of that set, which includes suppliers and maintenance businesses as well as installers.

  Their workers are among the most disrespectful individuals you will encounter in the local area. They hire men with no values whatsoever or public respect. A reflection of "George," I am sure.

  My husband and I spent about $250,000 with Harmony Energy in total between solar panels at our office and our home. We lost $6,000 in solar credit by not being informed that we needed to switch the supplier to Eversource. For Harmony Energy to receive such a large amount of business, more meticulous care and insured delivery of critical information should have been provided to the customer. We should have gone with 603 Solar or Revision Energy. In addition, Harmony Energy installed solar panels beyond the owned area of our roof putting us at financial risk with the other owners in the associat

  Took our $1500 deposit, proposed a project not permissible according to Hampton building codes, failed to show up multiple times to hearing to seek easement and then we never heard from them again. Would give 0 stars if we could.

  Working with this team to install solar panels and a battery backup at my home has been an exceptional experience. After researching several companies, I found this one to be extremely knowledgeable and professional. Throughout the entire process, the team demonstrated expertise and professionalism, helping me choose the ideal setup and guiding me toward the best resource combinations. The installation crew did a fantastic job placing the panels on my roof, integrating the battery into my electrical system, and providing ongoing technical support after the sale. If you’re thinking about instal

  Harmony, as a company, responded well to my DIY-installed solar system, diagnosing and fixing a malfunctioning inverter, later replacing an under-performing panel, with an alternative, under warranty, and the latest assistance, filling out the Maine solar tax exemption form. Sincere gratitude to Jay, their Project Manager, from a long-in-the-tooth, fellow PM, for the latter task, undertaken, gratis.

  I had a solar tracker installed in 2018 and I noticed it wasn't working. I called and spoke to Jay and he told me to try and couple of things before he sends out someone to look at it. I did what he asked and it didn't work. So I called him the back the next day and within 2 hours they were here to look at it. They replaced a part that was under warranty and then figured out what was wrong. Within a hour my tracker was up and running again. Thank you Jay and crew for getting us back up and working so quickly. Service was excellent Jim p

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.

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

• Established

  “Shawn Donovan has worked for Harmony since 2010 and brings to our organization years…”

• Years in business

  “in Electrical Engineering and has more than 35 years experience. George has had a…”

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

• Google also lists this company under roofing. A company that does both roofing and solar can handle the roof work a panel install often needs.
• It is also reviewed on Yelp. 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.

• —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.
