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. The Power Grid is the red one. The amber line is the middle of that set, which includes suppliers and maintenance businesses as well as installers.

  Let me start by saying that I’m not usually someone who leaves positive or negative reviews, but I felt I had to share my experience with Anthony and his solar company.

At first, everything sounded almost too good to be true, but my wife and I decided to give it a shot—and I’m very glad we did.

  Anthony was great to work with getting our solar system set up. He is very knowledgeable about the solar system and he took his time to explain everything to us. We have not had a bill since we had them installed 3 years ago, we only pay …

  Anthony visited my home at least three times for over an hour each time to go through the whole process of solar with me and my family. I was extremely hesitant but he answered every question I had in detail. I wish I did it sooner especially with smart meters and seasonal rate hikes. Right now National Grid owes me over $300. It’s a good feeling. My only regret is not maxing out my roof. Anyone aggravated with NG or other major carriers just has to call and ask for Anthony.

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 found nothing on a website for this company that states a warranty, a licence or how long it has traded.
• —Google publishes no street address for this company, so we cannot say which town it is based in. Derry is the area its listing was returned for, not an address we hold.
• —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.
