Where other contractors canceled appointments, arrived late, or were just no-shows - Mikel (out of their Hudson office) arrived on time and did a thorough assessment of the roof including taking drone footage. He sat with me and walked me through the whole process clearly, explaining all my choices in materials and didn't push any product or add-on. I did receive marginally cheaper quotes, but they did not leave me feeling like my home was in good hands in the same way that Mikel did, and I felt the extra money was likely to be worth it. Once I decided to go ahead with them, again, everything was done very professionally. I was kept informed of times and everybody showed up exactly when they said they would. I made a small change to the scope of the work in replacing additional plywood sections of the roof, and these were easily accommodated on short notice. On the day of the work, the crew showed up on time and Jurgan (the site foreman) kept everything moving with minimal disruption to us. I was working from home, and my wife and kids were in and out of the house for school and errands. Despite replacing the entire roof of the main building and two additions over approximately 9 hours, there was minimal disruption to our days. The house was protected during the work, and even with snow still on the ground, their cleanup crew constantly walked the property picking up and disposing of any debris, nails, old material etc. Ultimately the roof was replaced successfully and looks good. Every step of the job was explained to me, every question answered, and every decision explained. The team was professional, punctual and courteous throughout. A couple of weeks in and we've had snow, rain and strong winds. Everything is still perfect. I can highly recommend Mikel and Jurgan from Golden Group, Hudson.

I talked to absolutely every one about a solar panel installation. I easily spent months on…read moreresearching the topic, vendors, and installation techniques. Ultimately I settled on on a mechanically mounted system for my flat roof, which was wonderful. Some vendors would not touch a flat roof. Some only installed ballasted systems. Some vendors assumed that they could use a lift to get onto my roof when they actually needed a crane. Some just wanted to overcharge me with the hot new technology, sweeping the nation. After reviewing multiple bids, I settled on Sunbug to install my system. Chris Miller was a no nonsense saleman throughout my whole research phase. He answered all of my questions, and disabused me of any misinformation I may have had. He was polite, but firm, which is exactly what a layman consumer needs when making a large, delayed gratification purchase like a solar system. Once I signed on the dotted line, their team actually moved fairly quickly through the rest of the process. We were able to install my system before the end of the tax year, so some of that delayed gratification is delayed just a little less. I would give a five star review, but there were a few hiccups. Once I signed the dotted line, the team was less responsive than I needed with my subsequent questions. They installed the inverter in my basement without my input, which is a problem when I plan to finish my basement. We quickly fixed that by simply moving it, but we could have avoided that problem altogether by filling me in on the plan first. I chalk that up to some disorganization, and rushing to complete systems before the end of the tax year. Another silly issue is that their electrician upgraded me to a 200A panel, which is wonderful. For some reason though he reinstalled the same 100A main breaker I originally had, which makes no sense. Now I have to pay some one else to upgrade my main breaker. A month later I am actually still waiting for an inspector to check off on their work so that I can turn the system on, but that may be more an issue with the inspector than with Sunbug. In any event, I am mostly pleased with my purchase, and look forward to bathing my roof in sun shine in the coming years.

I recommend Green Power Energy if you're considering getting solar panels. If you're unsure, request a free quote and ask your questions--they did not pressure or try to "close" me. I collected all my quotes, compared them, and then called them back when I decided.

From the very beginning, with initial outreach, to the installation, to the system start-up, and to follow up requests, everything was AMAZING. First off, the initial consultation and discussion of the possibilities was exactly how every experience should be. There was no pressure whatsoever, and everything was explained clearly. The representative was super knowledgeable, and responded to all questions quickly. I had a quote within a day of the visit, and phone calls/e-mails with questions were answered promptly. From a price perspective, Great Sky was extremely competitive, something that I honestly did not expect based on everything the company offered. Once the contract was signed, GSS did a fantastic job working with me and the banks, Eversource, and MassSave to make the paperwork process a breeze. During the installation, I continued to be impressed by the GSS folks. Everyone showed up on time, were respectful of my property, and cleaned up at the end as if they were never there- Something that is relatively rare when it comes to construction crews. When I unfortunately did run into issues with my PV system (nothing related to anything GSS did), they were just as impressive with assisting in getting a resolution each time. They communicated with the appropriate parties, including equipment manufacturers, and the State reporting agency, and got my system back up quickly. Overall, I have not one bad thing to say about Great Sky, and it is the only company I recommend to friends and family when they tell me they are considered installing solar panels. Good them a call, you will be glad you did!

Their products are top of the line and their prices are very competitive (after having researched 5 other companies).

After doing a little research and asking around we chose to go to with Isaksen Solar and I HIGHLY RECOMMEND! From the very first consultation to the final installation, our experience was excellent. They took the time to explain the process in detail, answered all my questions, and made sure I felt confident in my decision to make the change to solar. The installation crew was on time, respectful, and worked great together. They completed the work on schedule and left the working areas exactly the way it was when they arrived. I couldn't be happier with how easily the system was integrated with my home, both aesthetically and functionally as seen in the pictures. Their whole team outdid themselves with their commitment to me as a customer from start to finish. They followed up after the installation to ensure everything was running smoothly and that I understood how to monitor my system's productivity. If you're considering solar, Isaksen is definitely the way to go! They made the entire process easy, transparent, and worry-free.
