  • "Great Sky does awesome work!"

    Reviewed Jan 17, 2021

    Great Sky installed my solar system 2 years ago. They were by far the most responsive to our needs (we were in a rush to get it installed before the SREC-II system ran out, and they accommodated). They offered a couple of options, and we went with the most practical. They got the work done quickly, and they system has worked great since then.

  • "Excellent Experience"

    Reviewed Jan 09, 2021

    I am a year into my installation that was done by Great Sky Solar. They went out of their way to meet my needs and even went as far as to financially reimburse me for missing an "estimate" installation date that was out of both of our control. The system has been over performing according to contract estimates and I have not had a bill in the year since the install. Excellent customer service experience with a professional crew that ensured I knew how the system worked. They handled the scheduling of all inspections and were present on-site with the local building inspectors. Highly recommend using Great Sky Solar for a personal experience with a knowledgable staff from the top down.

    Great Sky installed our solar panels our earlier this year and we have been enjoying solar power since mid-April.  

    We found Great Sky to be very responsive, courteous, and fair. They communicated very well with us throughout the process from design to selection of options to installation. The installation itself was done professionally. They took care of all of the permits including interfacing with the utility and the town for the inspection. They also took care of the application for SMART credits such that we did not have to do anything. They kept us abreast of these background activities and so I was aware of what was going on.

    All in all we had a great experience with Great Sky Solar and I whole heatedly recommend them.

    "Great Sky Solar Stands Out Among All Installers"

    Reviewed Jan 02, 2021

    We started looking to put in a solar system at our home in early 2020 and sought quotes and assessments from numerous potential providers. Right from the start, Great Sky Solar's proposal stood out because they evaluated our specific situation, provided visualizations of our property, and gave detailed quantitative production estimates, as opposed proposals from many others that were obviously generated by one-size-fits all automated programs. The fact that Great Sky Solar offers a production guarantee (based on measurements taken from our actual rooftop) took most of the uncertainty out of financial calculations and also helps us greatly with future plans for home energy redesigns. 6+ months in, we are comfortably on track to outperform the first year guarantee.

    We took them up on an offer for an initial visit to answer questions and were impressed and reassured by David's deep technical know-how. We were further attracted by the fact Great Sky's installers are actually employed by the company and paid a living wage; this clearly showed in the professionalism of the workers and the no-worries quality of the installation. Despite COVID disruptions, our installation took place largely as planned. The Great Sky took care of every part of the complex permitting and sign-up process for state solar incentives, providing regular status updates as requested.

    Despite all of these benefits in personalized planning, deep technical knowledge, top quality craftsmanship, on time delivery, and a production guarantee, Great Sky was still among the lower cost providers (although not the low bid). If you live in their service area, they are absolutely worth strong consideration for your solar project!

    We installed our solar panels almost two years ago. Friends had used Great Sky Solar for their installation, other friends knew the operations manager from the installation of panels on their home, before he starting work with Great Sky and both spoke highly of the company and the individual. So we decided to engage with them for the study and later the installation of the solar panels at our home. We were impressed with their knowledge, their time management, and most importantly there no nonsense attitude. Once we signed the contract, we were always in the loop, and consulted, if need be, but the process was smooth, the interactions transparent and the results excellent. The benefits from the installation have been terrific and we are delighted that we worked with Great Sky Solar.

  • "Amazing work!"

    Reviewed Dec 29, 2020

    I spoke to several different providers while getting quotes for my project, and Great Sky was the most helpful. They spent more time answering my technical questions than convincing me how much money I would save (something I already knew before I decided to buy solar!). They also came in at the lowest cost, by a little. That they don't use contractors for the work was also a big selling point for me.

    The installation process was remarkably fast. I had a site visit, and once the build was scheduled, they were in and out in a single day. The panels and power boxes on the side of the house were neatly and cleanly installed, and a hole in the interior wall that was needed near the main panel was repaired quickly and well. Their employees explained the system to me in a patient and helpful manner so that I'd understand how to operate it.

    After the install, Great Sky remained communicative as the local power company took several weeks to catch up with their backlog.

    All in all a great experience and I highly recommend them for your own solar projects.

  • "really worth it!"

    When I was exploring solar panels in 2016, Great Sky was the only company that took the time to listen to my situation and concerns and to explain everything. They helped with all the details for rebates, and installation went very smoothly. I was a bit doubtful about the financial value, but it's been wonderful. And when I wanted another gauge (to view electricity usage), Great Sky obtained it and installed it. I highly recommend Great Sky; very nice people who care about customers and solar.

They delivered exactly what they promised, were extremely responsive and their installers did an outstanding job. Overall I had an excellent experience with Great Sky Solar and would highly recommend them and their services for anybody interested in going solar.

  • "Great small firm"

    Reviewed Dec 24, 2020

    These guys did a great job on our solar installation about three and a half years ago, and everything has been going smoothly since. When we had our house painted this summer and the painters got paint on the solar panels, we called Great Sky and they immediately got back to us with advice about how to clean the panels. They even stopped by a couple of weeks ago to let me know the router in the basement had stopped transmitting data (it had come unplugged) and to make sure everything was up and running. I have recommended Great Sky to a couple of friends for their solar installations as well.

  • "Wonderful to Work with"

    Reviewed Dec 23, 2020

    Great Sky Solar was terrific and we highly recommend them. We have a small cottage. Another larger company kind of wrote us off--they said we couldn't fit many panels and clearly were not interested in the job. Great Sky said they could fit more. In the end, we went with them because of that, because they were responsive and pleasant, and because they are worker-owned. We wanted to support a cooperative.
    Great Sky worked to fill every inch of the roof and maximize the number of panels. They also worked around a skylight so we could still use it, placing large brackets so that even if it was partially covered, we could still open the skylight for ventilation and some light. They replaced the electrical panel and installed squirrel guards and a consumption meter. In short, it was a complicated job, with several visits.
    They did recommend against a 15th panel because they said because of a sub-optimal location it wouldn't return the investment very soon, and we liked that they don't try to oversell. We went with that last panel anyway, just because we wanted to maximize the capacity and get to a zero electricity bill. After the system was up, they helped us with the online interface, the financials, every step of the way.
    In the end, we ended up with a great system, no technical problems, and we run up a credit on our electricity bill for 9 months of the year. The other three winter months we use more than we produce, but we still come out of the winter with a credit.
    I had shopped for solar 6+ years ago, but it would have taken many years to pay off the investment. When we installed in 2018 it looked like that time was cut to just a few years. We're on track to do so and we're very happy with our system. If we ever move, we'll have increased the selling price of our house. If we move to a house w/out solar, we would work with Great Sky again in an instant.

    Purchasing a home solar system was a big deal, and my son and I were very thorough in researching and selecting what we feel were the best inverters, panels, and installer for the cost. We researched 15+ installers and narrowed it down to 4 of them to meet in person and raise the exact same questions/concerns, listen to their advice, and carefully consider their proposals. We were fortunate to have met what we believe were 4 very good candidates, but in the end David at Great Sky Solar was tops--in terms of both expected quality and cost. David and his team are true professionals in their industry, and they write contractual terms that are very favorable to their customer in order to, as David himself puts it, keep their own "feet to the fire" to ensure complete customer satisfaction both during the install and for years after. It's been 6 months since our install was done, and we are completely satisfied and confident that Great Sky will be there if anything goes awry in the future.

He came by, with a ladder, went up to the roof to give feedback about was the roof in good enough condition, would it be possible to have panels given the number of trees in the area (and other relevant questions). He was so helpful as were the other member of the team that I talked to about panels and the process, etc. The company discussed every detail of their proposal and we discussed adding some panels to further optimize production.

    I did considerable research on many solar installation companies in the fall of 2019. I chose Great Sky Solar because they clearly explained the pros and cons of residential solar; helped me cut through the jargon to understand the technical essence of panels, inverters, monitoring systems, and tax credits; and provided several different designs and helped me choose the best one for my house. They even extended a 4% rebate since my installation would take place in 2020 at a 26% federal tax credit versus the 30% tax credit if the installation occurred in 2019.

    We were scheduled to install my panels in mid-March of 2020...and you know what happened next. COVID-19 interrupted our lives. Great Sky Solar's installation schedule was delayed due to COVID restrictions, but they stayed in touch with me and provided frequent updates, and were able to install my solar panels in early June.

    I decided to upgrade my main electrical panel at the same time. Great Sky Solar provided detailed specs for the panel, but the electrical contractor I hired to do the work installed the wrong panel, delaying my ability to begin solar production until early October. Great Sky Solar supported my efforts to get the electrical contractor to admit their mistake and pay me for the lost solar production from June to October, and much to my surprise (and delight) the electrical contractor reimbursed me for the lost production...thanks to Great Sky Solar going to bat for me.

    Great Sky Solar stuck with me through COVID and through electrical contractor issues, and have been a great partner throughout the journey.

    I work at an organization with several buildings that have solar, and I was very involved in that process. So when it came to getting solar on my own roof, I knew I wanted to be picky. I interviewed about 5 different solar companies - including the big ones like Vivint, Boston Solar, Solar City - and Great Sky blew them out of the water. Why? Because I could tell they were being absolutely honest with me about their company, how it works, and why they are different. They fully employ their team of electricians vs outsource them. They explained how the whole industry works, and why they don't do things like incentivize electricians to install as quickly as humanly possible, or sell sales leads to salesmen and hold them accountable to "get paid back" via commissions. No issues with the system so far and I love getting just a few electric bills per year, plus my quarterly REC checks. And the system looks great - they chose nearly invisible racking and there is no ugly conduit visible from the roof to the inverter. Highly recommend!

    I performed diligence on several solar companies, both large and small. I quickly determined that purchasing my own system (through a loan from Mass Solar Program) was the best route, because it gives you additional bargaining power. I ended up going with David from Great Sky Solar, mostly because I felt he was the most transparent with costs and the only one who truly used a no pressure sales technique. Their quote was in the middle of several others.

    They installed the system, on time and as expected in March of 2016. It's worked perfectly. One february, my son accidentally switched off the external second meter (so the power could not flow back into the grid). I didn't realize it at the time but Great Sky called me to let me know I wasn't making power and offered to come fix it for free if there was a problem (there wasn't, I just had to move the switch back).

    I've recently contacted them about expanding my current system. Instead of an immediate yes, lets do it, they take the time to crunch the numbers, determine all my benefits (given the current SREC market) and do a break even analysis. It ended up being about 5 years out, and David suggested that I might want to wait to see if panel prices come down or incentives get better. Again, transparency. I am usually someone who makes decision on price. Interactions with this company have given me faith that cheapest isn't always best, and having piece of mind and doing business with a company that appears to look beyond quarterly numbers in the long run is more rewarding. I will continue to give them my business in the future for that reason.

    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 I already knew about solar and it's various systems I knew I could vet a company that would treat us right.

    What impressed me most about GSS that I don't think is mentioned here very much, is that I never felt any hard bargaining, hard selling, or up-selling of any form. GSS (and other installers) didn't know initially I had any knowledge of solar, so I could patiently listen and see what they offer and how they would approach our install/house. Once I started asking questions, installers would quickly figure out I knew a thing or two. It was here that GSS won me over, because they sell reliable products, with a professional install, and are VERY particular about aesthetics. Solar should be functional and can be 'fashionable' at the same time, ex. auxiliary piping and boxes in a convenient yet out of view location.

    Their pricing comes in line with other competitors, and our family was willing to come up a bit more since we felt that we shouldn't experience any problems with them. We were even able to quote a electric vehicle 'charging station' install since we have an EV with a charging station (240V), and since they were going to be working on our electricity we asked them if they could do this also. Not even a problem.

    Finally, GSS helped us through the whole process of getting into the SREC/SMART (the renewable credit) system so we can maximize our return. SREC is the old system, SMART is the new one.

    We are now 6 months after install, and we have had zero problems. No leaks (from roof), no panel outages, and the system just simply works. We are producing energy and receiving credit from the SREC/SMART network. Couldn't be happier. Thank you GSS!

    I really appreciated Great Sky's dedication to putting together a system that would work in circumstances typically avoided by the giants, who prefer cookie-cutter installations. I had minimal southern exposure (but as it turned out, very serviceable western exposure) and a municipal power company where I believe I was one of the first ten customers to make use of a newly introduced net metering policy. My electrical usage is very modest (about 2.4 MWh annually). In addition my application fell into a period of uncertainty for SREC II. Despite these apparently discouraging factors, Great Sky created proposals grounded in measurements taken from my roof, worked with my muni to understand their policies and meet their particular requirements, and kept me apprised of the evolving SREC II environment. Installation was professional and sensitive to appearances (even to the point of painting outside electrical conduit to match different trim and wall colors behind it!).

    I was very anxious to keep on top of any responsibilities I had to make sure the project moved forward and was executed properly, but in fact, Great Sky pretty much did it all for me. As anticipated, the system generated its first MWh in the first quarter of operation, and everything is set up to auction the associated SREC and deposit proceeds automatically. Most months my electrical bill is a credit that offsets some of my gas bill (from the same municipal power company).

    It was a bonus that the company is local, small, and looking to do the right thing, and not some outfit just looking to make a quick buck in the MA market.
