Catamount Solar

Catamount Solar is one of the more structurally distinctive residential solar installers our research team reviewed in Vermont. Founded in 2011 and operating from 44 Hull Street, Suite 3 in Randolph, Vermont, the company is organized as an employee-owned worker's cooperative, meaning the technicians, designers, and project managers who actually build the systems also collectively own the business. That structure is rare in residential solar and aligns the long-term interests of the people doing the work with the long-term performance of the systems they install. What stood out is the credentialing depth for a company of this size. Catamount Solar holds NABCEP certification, the recognized industry standard for residential solar installation professionals, and the team specializes in both standard grid-tied photovoltaic installations and off-grid solar projects, which require materially more design and electrical expertise than a typical rooftop system. The company also installs battery backup systems for grid-outage protection. As a member-owned cooperative, Catamount commits to donating five percent of profits to local community organizations in central Vermont and runs a profit-sharing program for its member owners. Prospective customers should set realistic expectations about scale. Catamount's verified review base is comparatively small, with roughly 44 Google reviews at a 4.9 average at the time of our research, which reflects the company's deliberate focus on quality over volume rather than any negative signal. Project lead times can run longer than higher-volume installers, particularly during the Vermont peak season, and the cooperative structure means the company is less aggressive on dealer-fee financing arrangements that larger installers use to push down headline pricing. Buyers prioritizing a long-tenured, locally rooted, mission-driven installer should give Catamount serious consideration, and should ask for off-grid or battery backup references if their project involves either. With a composite score of 68.5 out of 100, Catamount Solar holds the third-ranked position in Vermont for 2026.
