Kaitlyn E, Williston, VT

“We shopped around for solar for our home (roof-mounted) and Green Mountain Solar had the best service and value. They explained everything, the process was easy and clear, and the installation was so quick. They did a great job and we look forward to going into our first full summer with the panels, to see how much of our annual usage we can offset.”

Drew G, Williston, VT

“If you’re shopping for solar in Vermont, Green Mountain Solar is the only way to go (it’s in the name for goodness sake!). The staff redefined “customer service” treating us as far more than customers. The entire team is a wealth of knowledge, conscious of safety protocols, extremely responsive, and above all else – respectful. They made the whole process fun and exciting. We’re proud to have solar on our home, and all the more proud to say Green Mountain Solar put it there!”

Nick M, Georgia, VT

“WOW, I LOVE my new system! Thank you GMS!!
My wife and I have always been interested in the possibility of going solar. The idea of using renewable energy and doing “our part” to help the environment is very important to us. After moving into our new home in Georgia, VT this summer, I decided to begin looking seriously at various solar companies. Green Mountain Solar quickly rose to the top of our list due to being a local small business with excellent reviews for its customer service. After an inquiry on their website, I was promptly contacted by their sales rep Marcus who completed a site assessment and walked us through all of the options. GMS has formed key partnerships with local financial institutions to offer VERY LOW 1.99% interest rates which makes buying the system more desirable so we opted for an oversized system to meet both the needs of today’s and tomorrow’s power consumption. Their Office Manager Tara is one of the most diligent professionals I’ve worked with in quite some time as she has kept us updated every step of the way. They even moved up our install sooner so we could begin getting the full benefit of the summer sunshine a little early! I watched the entire install over the 2 days and was impressed with how solid the products looked. The electrical and conduit work was exceptional (and I am a very picky person) and even though they had a few bumps along the way (as do most businesses), I consider this an awesome experience, and they come highly recommended. Any issues were quickly resolved. The end result was an awesome new system that really produces LOTS of power. We have since been able to install a new mini-split AC system and a hybrid water heater for zero extra power costs to run! THANK YOU GMS!”

Geoff K, Williamsville, VT

“As I was investigating solar and making a list of installers who could tackle our rooftop project, I was impressed with what I saw on the Green Mountain Solar website. There was lots of information about all the components they use. There was considerable detail on the process and what to expect. And there were loads of customer referrals offering praise and expressing satisfaction with the work GMS did. The extended warranty, the helpful phone contacts with staff, and the remarkably positive comments from a customer I called confirmed my choice. I mostly spoke with Marcus on the phone and during a site visit, but all the folks I dealt with before and during install were helpful, positive and seemed invested in doing a fine job. Our 9K system completely filled the south face of our new garage roof and looked as if we’d designed the building around the panels–which is to say it looks great. The output of the panels has more than met expectation, and the Enlighten app for the Enphase micro inverters has proved a super way to monitor the system. Bravo GMS, and thanks.”

Wayne F, Montpelier, VT

“We considered installing a solar installation for several years. We reached out to several companies and had positive experiences with all of them. We decided to employ GMS because they were the most responsive and thorough. All the paperwork covering the panels, the battery two heat pumps, and payment schedule was timely, understandable, and well organized. All our inquiries were promptly addressed. The crews that installed the systems knew exactly what to do and they interacted well with us and each other. They showed up on time and left a clean job site. This was an expensive project and having a competent, responsive crew gives us a very high level of confidence/comfort in their work product.”

Liz B, Plainfield, VT

“Deciding to invest in solar panels is a big deal, and I got estimates from two companies based on prior reviews. GMS was by far the better option for me, as the salesperson actually came to my house and investigated the possibilities before providing a quote. He was a good communicator throughout. The other company just looked at my house on Google maps and sent me follow-up emails that seemed automatically generated (AI?). The GMS installation of storage battery and panels went smoothly, just taking 4 days total. I wasn’t anticipating that there would be various apps to control the system, but they’re not too complicated, and it’s fun seeing that you’ve made some electricity, even in winter. GMS worked well with my electric company, who are known to be a little difficult, and the new meter (recording power in and out) was installed within the 10-day window. I recommend GMS!”

Executed a difficult solar install on our old house. The team was knowledgeable and courteous, and stuck to their price even though it was a tricky install. System looks and works great! Don't be fooled by lower priced systems, individual inverters is where it's at!

What an awesome experience using Green Mountain Solar. Ian and his team came out to my house and explained all the options and what would be best for my house and situation. Work was done cleanly and quickly, total pros! once I have have my shop built and have more roof top space I’ll be using Green Mtn again for more solar. Thanks again Trav

GMS installed 19 panels on our roof and woodshed. Entire process was very smooth from initial contact and site survey to installation. All panels up and running in two days. Excellent service and communications. We are very satisfied.

Worked with GMS to design and install a 13.7kWh ground-mounted solar array at our property in Woodstock, and everything about the experience was exemplary. Our consultant, Ian, was a fount of knowledge, ready to answer any questions but also keenly interested in our needs and desires for the project. When new, more efficient panels became available while we were waiting for the spring thaw, the team at GMS looked out for us and ensured that we got the newer equipment. I can’t recommend GMS strongly enough, and I have no doubt that we’ll go back to them to add battery backup capabilities to our system once some other prerequisite work on the property is out of the way.

Job: installed two GMP-leased backup batteries on a plywood wall/box. GMS was easy to work with: clear, patient, timely communication; quality installation work; friendly, responsible installers.

GMS recently installed a Tesla storage system as an alternative for a stand alone generator for power outages. Shannon evaluated our situation and made a recommendation. He was great to work with. The installers, Mike and Avery, exceeded our expectations. Very knowledgeable and just plain nice to interact with. Can’t say enough good things about the entire project. HIGHLY RECOMMEND.

GMS seems to be a company that has a good feel for the customer experience they want to deliver. They don't pressure, they follow up gently, they respond promptly, and they show up when they say they're going to. I shopped around for my solar project and GMS was competitively priced, but it was the follow-through and responses to my many questions which sold me. My sales advisor Casey was great - she let me know about all the extra fees and potential pitfalls up front, connected me with their loan partner, and was patient, respectful, and supportive as I navigated each decision point and roadblock. Their installers came to my house for two separate portions of the project, as the ESS installation occurred about a month before the rooftop was clear enough for the rack mounting. At all times, they were professional, friendly, and happy to answer questions. I really appreciated that they asked for my preference when choosing where to go through my walls and where to mount the switches and control panels. They also cleaned up after themselves and were accommodating to a post-installation request to manually adjust a cabinet latch that had been blocked by a subsequently installed conduit. Most importantly of all, the system they designed and installed is delivering as promised. We installed at the end of March, and my net usage zeroed out in April (with surplus). What more can one ask? Because they seem to be well-organized and well-run, I have confidence that GMS will still be there years from now, to honor their customer commitment if I ever need help troubleshooting or making a warranty claim. This is an investment I would gladly make again, and I'm happy to recommend Green Mountain Solar to anyone who is in the market for a solar vendor.
