Green Mountain Solar
Detailed Profile
Green Mountain Solar has served South Burlington and the Champlain Valley for 9 years, establishing themselves as a dedicated solar installer in a state that consistently ranks among the most solar-friendly per capita in the nation. Their NABCEP certification places them among a select group of Vermont installers who have met the industry's highest professional standard, and their perfect 5.0-star Google rating from 289 reviews is a standout metric that reflects exceptional customer satisfaction.
What makes Green Mountain Solar's perfect rating particularly meaningful is the volume behind it. A 5.0-star rating from nearly 300 reviews across nine years of operation suggests a company that has maintained flawless customer relationships across hundreds of installations and multiple seasons of system performance verification. Customers consistently praise clear communication, professional installation crews, and systems that meet or exceed projected energy production estimates.
Green Mountain Solar focuses exclusively on solar energy, which gives them a depth of specialization that multi-trade contractors who offer solar as an add-on service cannot match. Their design team understands how Vermont's seasonal irradiance patterns, snow loads, and grid policies should influence system design decisions. They work with premium panel manufacturers and pair systems with modern inverter technology to optimize production in a northern climate where maximizing energy harvest during shorter winter days requires careful attention to panel orientation, tilt angle, and shading analysis.
Vermont's renewable energy landscape rewards informed installers. The state's net metering program, administered through Green Mountain Power and other utilities, offers favorable compensation for solar production, but navigating the application and interconnection process requires familiarity with utility-specific requirements. Green Mountain Solar's dedicated focus on the Vermont market means they have processed these applications hundreds of times and understand how to avoid the administrative delays that can slow less experienced installers.
With a composite score of 72.1 out of 100, Green Mountain Solar holds the third-ranked position in Vermont for 2026.
