Great Sky Solar

It has been about a year since my install, and I can say that Great Sky Solar did a great job with the installation. They were very responsive with questions about the process and communicating any changes that need to be made. The electricity generated over the first year was pretty much spot on with the estimate (within 200 kWH).

I would start by saying that taking on a solar project is not for the faint of heart or the impatient

Excellent experience from start to finish. Great Sky offered a very competitive bid and held my hand through every step of setup design, planning for installation, and navigating the utility interconnection and net metering processes. I chose Great Sky specifically because they're an established company and offer a production guarantee, but I was surprised and impressed with their customer service and responsiveness to my questions throughout. The system was actually up and running ahead of schedule (and thankfully ahead of a brutal 3-day heat wave).

My solar panels were installed in 2014 by a company that has since gone out of business. When I found that a panel was not working I called 4 different installers. 3 days passed and no one returned my call. Then I called Great Sky. My call was returned in 2 days. The process and cost was explained to me and within a week the service men were at my door to fix the problem. They were friendly, courteous and efficient. I was left with a sense of comfort that I now had a competent company, ready and willing to help with my system should I ever need them again. Not only is this a legitimate and honest review, I generally DO NOT write reviews but Great Sky so impressed me I felt they were worth my time.

I've had a good experience with Great Sky Solar so far. They installed 23 panels in October 2023 on my roof in Eastern MA, and managed the process to achieve PTO in December 2023. Their pricing was competitive in the MA market. The major hiccup in the project was with the new NFPA codes. These mandate larger walkways on the rooftop -- unfortunately this removed four panels from the productive face of my house, and led to some being placed in a bit less optimal orientations. This wasn't the fault of Great Sky, it was a result of my town choosing 2023 to be the year that the new NFPA regs took effect. The rep and engineering teams were responsive to the changes needed. The onsite team was efficient, professional and polite. They left a clean jobsite each day, and communicated very well through the whole process. There was a problem with the IQ Combiner unit which was originally installed, so they came back quickly to replace the board with a new one from Enphase. So far our system has performed as per design.

Good communication from the office, polite and efficient installation crew, better pricing (and better quality panels) than others I was looking at. 18 months in and no issues.
