Vermont's S.202 was signed on June 16, 2026 and took effect on July 1, 2026, making it one of the first laws of the 2026 wave to be fully in force. The cap is 1,200 watts.
Vermont specifics
Vermont has a long tradition of net-metered rooftop solar and community solar. Plug-in solar fills a different niche: renters, condo owners and anyone who can't commit to a 20-year rooftop installation.
Sunshine is modest, especially in winter, so orientation and tilt are critical. A steeper angle helps the panels shed snow.
What plug-in solar is worth in Vermont
Vermont households pay an average of 23.75¢ per kWh, 30% above the US average of 18.31¢. With roughly 3.9 peak sun hours a day, here is what a well-placed system produces and saves. We assume panels facing south at about 30°, 86% system efficiency and 80% of output used on-site.

At Vermont's average residential rate of 23.75¢/kWh (EIA, July 2026) and about 3.9 peak sun hours a day, a south-facing, tilted 800 W kit saves roughly $186 a year, paying back a $900 kit in about 4.8 years. Vertical railing mounts produce about 30% less.
What is the maximum plug-in solar size in Vermont?
The law allows up to 1,200 watts of AC output. That's roughly the safe continuous load on a standard 15-amp household circuit.
