Before you buy in Maine

This page is informational research, not legal advice — and it can fall out of date quickly. Before installing anything, confirm the current law and its start date, any size limit, your local building and fire codes, your utility’s requirements, that the kit is certified as a complete system, your landlord or homeowners association (HOA) rules, a safe way to mount it, and the maker’s instructions.

A “no dedicated statewide law found” status does not settle those other utility, electrical, building, fire, property, or product-safety requirements.

A planning estimate, not a promise. It doesn’t check whether plug-in solar is legal where you live, whether a kit is certified, whether your outlet or mount is suitable, or whether your utility pays for surplus power.
