    We've been fortunate to have Green Mountain Solar install solar panels and follow-up that work with the design and installation of a solar battery back-up power system. Their website prominently claims that, "From free site assessments to seamless installation, we make going solar simple. Our team is based right here in Vermont and will guide you every step of the way – no pushy salespeople, just real support.". We can attest, without any hesitation, that these words could not ring truer! From our initial point of contact with Shannon Jackson, one of their senior solar advisors, to office personnel and the various installation teams for the various projects (who sometimes worked through extreme heat and other conditions without complaint or letting it get in the way of their work), one could not ask for a more competent, professional, helpful and pleasant group of folks! They were/are truly a pleasure to coordinate with and we could not be happier with their work! Erik Bushey Fairfield, Vermont

    GMS installed a 10.32kW DC roof-mounted solar array with 11.5 battery system on my barn and I could not be happier. From the first site visit, to proposal, to scheduling and coordinating with our local utility and to the installation itself, the entire process was extremely efficient and successful. GMS was always very responsive to questions, transparent in every way and delivered exactly what the proposal specified. Ian Veralli made the site visit, prepared the proposal and followed through when I needed right through installation. Extremely professional and willing to address any question, no matter how technical (I am a professor at MIT in building technology) Ian set a high bar for the entire GMS team and they all delivered, on time, on budget and now I am fully running on solar power (right now on a partly cloudy day my system is producing 9.5kW!). I am super satisfied and would recommend Ian and the entire GMS team for any size and kind of solar installation.

    GMS did a great job on a challenging timeline. We wanted to get our project done by the end of the year so we could take advantage of the expiring tax credits and they got it done! Ian the sales/designer was great. He came out to the house a couple of extra times to meet with our electrician which was very helpful. The installation team was top-notch. We have an older/historic house and it is always a pain to retrofit/run new wires etc... They did a really good job and were respectful of how everything would look in the end. Definitely will use GMS again if we have another solar project.

    Everything was professional and efficient from the first meeting until the installation of our solar system and storage batteries. We started the process this summer and were worried that we wouldn't be able to finish the installation by the end of the year. But Ian Veralli and the entire team were great about creating proposals, walking us through all the steps and helped us to make a quick decision. The permitting and installation process was fast and efficient. We always felt well informed and we're very happy with our system
