Solar companies in Maine

Maine has more solar per person than any other state. Total capacity has grown from just 17 megawatts in 2015 to more than 1,600 megawatts today — roughly 700 watts of distributed solar for every Mainer, the highest rate in the country — and the state blew past its own 750-megawatt solar goal years early. Community solar farms get much of the credit, but rooftop systems are spreading steadily too, and modern panels produce well in Maine's cold, bright winters.

Homeowners earn credits under Net Energy Billing: its kWh Credit Program works like traditional net metering — production and consumption are netted monthly, and excess kilowatt-hours roll onto your next bill within a 12-month window. A 2025 law (L.D. 1777) reworked the program for large shared and front-of-the-meter projects, but behind-the-meter home systems under 1 MW pay none of the new project charges. No suitable roof? Community solar subscriptions have been the other route in Maine — the state is redesigning that program in 2026, so check current availability before counting on it.

The installers below serve homeowners from Portland to Bangor. Ask each one how Net Energy Billing credits will land on your Central Maine Power or Versant bill, and browse our solar energy resources for guides to cold-climate production, batteries, and comparing quotes.
