Good experience working with Great Sky Solar

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.

Great experience start to finish

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.

Great Work by Great Sky

Had a terrific experience with Great Sky Solar and highly recommend them. The communication throughout the process was excellent and thoroughly professional. They came when they said they'd come. The time line they laid out was followed. Even when a paperwork snafu resulted in a two part installation, they handled it directly, professionally and followed up as promised. Every staff member that we interacted with was friendly, knowledgeable and helpful. Very pleased!

Experience with Great Sky Solar.

I've experienced PV systems installed by Great Sky Solar on my church, on my roof and on a family member's roof. All the systems have been performing with no issues with the installation or equipment for years. I have only had to use their support to regain public access to the system's public web energy reporting for the church congregation that failed at the inverter company's site. It was resolved promptly! I strongly recommend Great Sky Solar to anyone in the greater Boston area, who is considering purchasing a PV system. Note: With this kind of reliability, I recommend purchasing your system even if you have to arrange financing, so you have full ownership of the system's value, tax rebates, SRECs, etc. I really enjoy getting an electric bill that says DO NOT PAY, because all the electricity that I used was balanced by the electricity generated.

Very Satisfied Customer

We’ve just hit my one-year anniversary with the system and are very pleased with what was done installing and operating the system. We signed the contract in August last year when Great Sky Solar was extremely busy trying to get clients up and running for the year-end tax credit. It took a little time to get the project started, but once it did things went very quickly. Installation took two days for 33 panels and all the trash was cleaned up. Everyone sent to me by Great Sky was quite professional and respectful. Great Sky did not use subcontractors, which I think is part of the quality work that was done. The team worked rapidly, and the installation looks very clean and professional. In visually compared my installation to other solar installations and think the work done by Great Sky is much more visually appealing than others I have seen. The system has performed flawlessly over the past year and exceeded my expectation as it hasn’t had a single issue all year. I have recommended Great Sky to others and would not hesitate to do so again.

Lexington Project

We chose Great Sky Solar after reviewing several proposals received through the Energy Sage vendor selection process. We found this to be an excellent way to get installer proposals without being exposed to unwanted sales contacts. Great Sky has proven to be an excellent partner in this somewhat complex process. Each phase of the project was handled professionally, from computer based estimates to permitting to actual installation. We couldn’t be happier with our choice of Great Sky as our solar partner. Highly recommended.
