"Steered me in the right direction" I stumbled onto this site by chance a couple years ago, and through that met the team at GSS. The thoughtfulness of the approach and the consideration they gave through the process sealed the deal for me. As others have said, crew came out an was professional and expedient through the whole process. They were monitoring the panels at the beginning and came out to replace a defective one even before I knew myself that I had a problem. So far the panels are producing the power we scoped for,... read more

"Excellent work and wonderful experience" We did quite a bit of shopping around for our solar rooftop install. Our house is from 1812 with a small, tricky 45 degree pitch roof, and I was very concerned about quality workmanship. Great Sky was the only company we spoke to who recommended relocating a vent pipe so we could install an extra panel on our roof. This was added work that other companies we talked to weren't interested in doing. It has been a year and a half since our install and everything is performing as promised... read more

"Good work, easy to work with" Great Sky Solar put 16 panels on our urban 3rd floor roof. They made the entire process relatively easy, and straightforward. We had full confidence in their work and their workers, and we especially liked supporting a worker-owned business.

"Great Sky Solar" I had solar panels installed on my roof in March of 2018 by Great Sky Solar. I can't say enough great things about my experience. They kept me up to date at all times as the project moved along and were always helpful and responsive to my questions and concerns. After having the system for about one year they have delivered everything that was promised. The quality of work was excellent and everything was clean and tidy at the end of the job. As someone who is obsessed with quality of work I was very satisf... read more

"I love my panels!" Great Sky was fabulous. I was a little concerned when I didn't hear from them after a month or so but now I know it takes about 3 months for the permitting with Eversource. The crew that installed the system was so great! They let us know that they drive by our house everyday so if there was any problem they could get it done first thing. There were a few adjustments in the first week because the system was producing so much energy so they switched out the inverter and I didn't know until I saw their truc... read more

"Best Installers by Far" I have had two separate solar installs done, and can say with extreme certainty that Great Sky Solar (GSS) is the best around. They are small enough to offer great communication and attention to customers, while also being efficient enough to offer the absolute best prices. Every member is very knowledgeable on the whole solar environment, and have great insights on all topics, from pricing, to materials, to financing and incentives.

"Excellent Experience" The installation was completed April 2018. It is true what the other reviewers have said, so, I will not repeat that. There were a couple of problems. One, I created (I know more than the solar installers syndrome) and the other involved my back up generator. Both were resolved at no additional expense. If I need to purchase solar panels again, I would definitely use Great Sky Solar without getting other estimates.

"Efficient, Clean, Friendly, and Knowledgeable" The team at GSS is top-notch. They are quick with responses, knowledgeable about their systems, friendly, and are conscious of cleanliness and running a clean install. Before moving to New England, I worked in the energy field (including solar) in California, yet mostly for large commercial projects. After scouting around I decided to go with GSS because of all the similar reasons that other reviews have already mentioned. Going solar for our family was a no brainer, and since ... read more
