Maine Solar Solutions
3,500+ Maine installations30-year labor + parts warranty
The Freeport specialist with the boldest published warranty in New England: 30 years on labor and parts, with NABCEP-certified installers statewide.
100% employee-owned since 2003Nearly 20,000 projects
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.
The 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.
Can you match the 30-year benchmark, or explain the gap?
Maine’s market leader publishes 30 years on labor and parts. Warranty depth is the visible differentiator in a simple-policy state; make every bidder address it.
What does my production look like in January?
Month-by-month production, snow-shedding tilt and low-sun reasoning belong in the design, not the disclaimer. An annual total alone hides the season that matters.
What is my one-to-one netting worth at my utility?
At roughly 30¢ power credited one to one, the quote should print the number plainly. Simple policy deserves simple math.
Who holds the electrical license, and whose crew installs my system?
Maine electricians license through the state’s Office of Professional and Occupational Regulation. In-house crews with named licensed electricians are the standard all three network firms meet.
Red Flags in a Maine Solar Pitch
A flat-looking production curve. Maine is seasonal; a model without a real winter came from another state’s software.
The expired federal credit still in the quote. Section 25D expired on December 31, 2025. Maine’s 30¢ math never needed it, and honest quotes show that.
Vague warranty language. In a state where the leader publishes 30 years, “industry standard coverage” is a dodge.
Large deposits before permits are filed. Modest scheduling deposits are normal; five figures up front is not.
