Maine Solar Solutions, ReVision Energy and Venture Home are the three installers in our vetted Maine network for 2026. Maine’s case is the simplest in the country, roughly 30¢ power credited one to one, so your decision comes down to execution: warranty depth, winter design and the crew that answers in year fifteen.
Our Top 3 Solar Companies in Maine
Each company below is checked against Maine’s electrical licensing, its published warranty terms, and real winters survived. Nobody paid to appear, and every fact comes from the company’s own materials, verified by our team.

Maine Solar Solutions

ReVision Energy
Northern New England’s employee-owned institution, installing solar, batteries and heat pumps with in-house crews across Maine, New Hampshire and Massachusetts. Companies owned by their crews rarely vanish mid-warranty.
Venture Home
EcoGen PartnerThe nine-state Northeast operator counts Maine at the top of its territory, with a 25-year warranty behind every install. Ask for the Maine-based crew and a recent local interconnection reference.
EcoGen Partner: Venture Home buys homeowner leads from EcoGen America. That relationship does not affect its place in this list. How we are paid

Whether Central Maine Power or Versant Power serves your address decides the arithmetic on this table. Both credit exported kilowatt-hours at your full retail rate under Maine’s net energy billing, but their supply rates differ by several cents, which moves payback by years on the same roof. Make each of the three model your utility’s current rate, not a statewide average, and show the January production assumption in writing.
