SunCommon

SunCommon has been one of Vermont's most recognizable residential solar PV brands since launching in 2012, operating from 442 US Route 2 in Waterbury and serving customers across Vermont and New York. Over the years the company has completed more than 10,000 solar installations across its two-state footprint, a scale that makes it one of the higher-volume dedicated solar installers in the Northeast outside of the major national players. What stood out to our research team is SunCommon's certification as a B Corporation in both Vermont and New York, a designation that requires passing a rigorous third-party assessment of governance, worker treatment, community impact, and environmental practices. That credential is uncommon in residential solar and signals a more mission-driven operating culture than a typical sales-led dealer. On the technical side, SunCommon has held NYSERDA Quality Solar Installer Platinum status for six consecutive years, which is the highest tier the New York State Energy Research and Development Authority awards, and the company installs both roof-mounted and ground-mounted residential systems along with battery storage and solar canopy structures. Prospective customers should weigh several considerations. SunCommon is the established Vermont solar brand and that recognition carries real value, but the company has been through ownership transitions in recent years, having been acquired by iSun in 2021 and then operating through subsequent corporate restructuring. Vermont customers report consistently positive installation experiences in third-party reviews, with Google profiles showing strong ratings, but our team noted that the company's pricing tends to land at the middle to higher end of the market rather than the value end. Buyers should expect a polished, full-service experience with above-average post-install support, and should ask pointed questions about current corporate structure, warranty backing, and which crew will actually perform their installation. With a composite score of 73.0 out of 100, SunCommon holds the second-ranked position in Vermont for 2026.
