Vermont homeowners pay an average of $0.222 per kilowatt-hour for electricity — nearly 60% above the national average — and that single fact does more to explain the state’s solar economics than almost anything else. When your baseline bill is high, every kilowatt-hour a solar panel produces is worth more in avoided cost, and your system pays itself back faster. According to NREL data, Vermont ranks among the top ten states in the Northeast for solar return on investment, with typical payback periods landing between 7 and 9 years for a well-sized residential system.
The policy environment reinforces those numbers. Vermont was one of the first states to adopt a strong net metering framework, and it has since expanded that framework into a “group net metering” structure that lets households join shared solar arrays — sometimes called solar gardens — even if their own roof is shaded, rented, or structurally unsuitable for panels. Add the federal 30% Investment Tax Credit (ITC), a state property tax exemption on the added home value from solar, and a sales tax exemption on solar equipment purchases, and the case for going solar in Vermont becomes difficult to dismiss.
The Green Mountain State’s smaller size and concentrated utility landscape — Green Mountain Power (GMP) serves roughly 75% of Vermont customers — also means the rules are relatively uniform compared with larger, more fragmented states. What follows covers the specific numbers, programs, and calculations Vermont homeowners need to make a confident decision.
