“I’m someone who does his research, especially on big purchases like solar. But this solar stuff is complicated! In the end, I’m so happy that I went with GMS over some of the bigger companies I was looking into that made me feel like just another sale. Every step of the process, GMS made me feel like I was in good hands, taking time to explain every step of the way.”

Casey and the installers at Green Mountain Solar were prompt and professional throughout the entire process. Casey sized up the job and sat with us to review the proposed installation, the economics behind it and the precise locations for future equipment.
Casey also followed up with precise unit dimensions for the particulate new product that was slated for installation and suggested alternate locations for the installers so that a best option could be identified.
Well done folks!

We had a very good experience with GMS. Our rep Ian was great to work with - he was attentive and met with us to answer our many questions about the install process, system function, metering, permitting, etc. He also followed up after install to ensure it was all working well.
The panel install was quick and happened ahead of schedule. The battery backup and metering install followed not too long afterward. The installers (all subcontractors) were flexible and worked with our requests for battery location and excluding several circuits from the battery backup system. All good since install!

Green Mountain Solar did a fantastic job installing a solar and battery backup system on my new home as it was being built. They were easy to work with and the price of the system was the best I was able to find

I had a great experience with GMS. They installed a 12.75 kWh roof-mounted solar array (using microinverters) and two 13.5kWh batteries. We reached out to 5 different companies and got quotes from three, including GMS. I felt GMS offered compelling products at a reasonable price and included a ton of detail to make me feel comfortable with what I was getting.
The team was super professional from the quoting process, to design, installation, and then tweaks to getting everything perfect. They were very responsive to all my concerns and questions. I can't say enough about the installation team. Super friendly, professional, and communicative.
Thanks for making our installation a major success. We will definitely use them if we expand our system in the future. We were looking at this project as phase I.

Green Mountain Solar installed a rooftop solar array in March 2024. Every aspect of our experience with both Shannon, our consultant, and the crew was exceptional—professional and knowledgeable. Shannon was incredibly helpful making suggestions, answering our numerous questions and being very responsive throughout the project. The installation crew was highly skilled and hard working. The project was completed without any issues. We would recommend them for anyone interested in adding solar to their house and would give them more than a five star review if we could!

We went with GMS for our roof-top solar array and battery back-up. Friendly and knowledgeable staff, a local company that supports the community, and a timely and efficient installation crew. What could be better?

Working with Green Mountain Solar was a pleasure from the first meeting to post-installation follow-up. Every GMS employee with whom we dealt was knowledgeable, informative, responsive and professional. On installation day, the work went without a hitch. I would give Green Mountain Solar even more stars than five if I could.

Green Mountain Solar installed an array on my house in March-2024 and it turned out great! I had been working with GMS for at least a year prior to that but needed to postpone the project due to unexpected house repairs. They were patient with us through all this and were still very responsive once my wife and I were ready to proceed with the solar project late 2023. Ian Veralli was our solar advisor and provided great support throughout the process! They do subcontract panel installation for some projects (including ours) but still maintain oversight. When they came to inspect the work done by the subcontractors they determined that touch-up work was needed to bring things up to GMS standards. For this they brought in their in-house team which completed the work quickly. The solar array has been doing a great job and hasn’t given us any issues. I would definitely recommend GMS to anyone interested in exploring solar.

This spring we decided to add solar panels to our roof, and a battery backup for our house. We were very impressed with the way that Green Mountain Solar led us through the process in turning this dream into reality. Our first meeting with their consultant was in person rather than online, and this same person helped us through the process from start to finish. Overall we are very happy with the decision we made to choose Green Mountain Solar over other competitors in the area, and we have been sure to speak their praises when talking to other people considering adding a solar to their household.

We worked with Green Mountain Solar to install a 10kW system for our home in Georgia, VT. Our rep was Casey and she was fantastic. They were highly responsive and helpful throughout the process, with great communication and customer service. We're really happy with the quality of the installation and would recommend them highly.

I researched several solar companies that operate here in Vermont and decided on GMS for a few reasons. First was the responsiveness and thoroughness of the sales rep (Shannon). He was prompt, courteous, professional and explain all of the in and outs of solar very well. The second was their reviews and feedback from other customers (a few were personal friends of mine) and they all recommended GMS also for a variety of reasons.
Overall the sale and installations went well. The panel were being installed on a large garage that I was getting built before the solar install so there was a fair amount of back and forth communication with the project team. Once we finalized on a date, the installers (and electrician) were here promptly on time and installed and fully connected the panels (27 of them!) in a day and a half. They worked extremely efficiently, professionally and were a pleasure to work with.
Then about a week later, Green Mountain Power came by and swapped the meter GMS installed with a new meter (to presumably deal with crediting back to the grid) about a week later and they completed that in less than 1 hour.
For those interested, you can also install an app on your phone and monitor the solar power production near real time. I included a few screenshots of that here also.
I'm looking forward to our first electricity bill (ya..I didn't think I'd ever say that either!) to see how much we will save!
Payback for us is estimated at 8.5 years and then it's no charges for electricity after that. A win for our pocket books and win for the environment.
I would highly recommend Green Mountain Solar for your needs if you are shopping.
