Do I need utility permission in Maine?

It depends on your state's rules and your utility. The safe path in Maine is to use a UL-listed (UL 3700) microinverter and check your utility's interconnection policy before you install; see the status for Maine above for specifics.

Maine now has a plug-in solar law. LD 1730, signed by Gov. Janet Mills on April 6, 2026, takes effect July 15, 2026. It allows systems up to 420W to be self-installed, while systems up to 1,200W require a licensed electrician, and it requires UL or an equivalent nationally recognized testing laboratory. Because electricity here is among the most expensive in the country, even a small plug-in kit can pay for itself unusually fast — one of the best states in the U.S. for balcony solar economics. Residential power mostly comes from Central Maine Power and Versant; before buying, confirm their interconnection or notification steps, stay within the wattage rules, and choose a UL-listed kit.

Before you buy in Maine

Call your electric utility and ask: (1) do they allow small plug-in / behind-the-meter grid-tied solar, and (2) is any notification or interconnection form required? Stay within the wattage they specify, use a UL-listed microinverter, and keep written confirmation.

Then estimate your numbers with our savings calculator (pre-loaded with Maine's rate).
