Need to know
- We rated 5 Maine solar companies on licensing, warranties, local presence, track record and options. The top three: Maine Solar Solutions (4, Very good), ReVision Energy (3.5, Good) and Venture Home (3.5, Good).
- Maine credits exported power kWh for kWh at the full price you pay, for Central Maine Power and Versant customers alike, but unused credits expire after 12 months and the fixed monthly charge stays.
- Maine licenses electricians, not companies. The master or limited electrician doing the work must get the permit first, so ask for that person’s name and license number and check it in the state lookup.
What solar costs in Maine
The 30% federal credit is gone for systems you own: in 2026 the price on the quote is the price you pay. Batteries and roof work cost extra. Compare each quote’s price per watt with these numbers.
Source: EcoGen Solar Cost Index, September 2026 Edition, prices as of September 25, 2026. Full breakdown: Maine solar panel prices.
Solar incentives, tax breaks and rebates in Maine
- Net energy billing
- Each kWh you send out becomes a kWh credit worth the full price you pay, about 24.68¢ on a Central Maine Power bill and more with Versant Power. Unused credits expire after 12 months.
- Property tax
- The value solar adds to your home is exempt if you file the Application for Renewable Energy Equipment Exemption with your town assessor by April 1. The system must be running on that date.
- Battery payments
- Efficiency Maine funds yearly payments of $126 to $180 per average kW your battery shares at busy hours, paid by the battery maker. There is no upfront rebate.
- Sales tax
- No sales tax exemption for solar equipment. Maine's general rate is 5.5%.
- Plug-in solar
- Since July 29, 2026, certified plug-in kits up to 420 watts per address are legal without utility approval, or 1,200 watts if a licensed electrician installs a dedicated circuit. They earn no bill credits.
- Federal credit
- The homeowner credit ended for systems finished after December 31, 2025. Maine has no state solar rebate or tax credit, and Maine Solar for All was ended in August 2025.

What to check with your utility
Central Maine Power
- Each kWh you export cancels a kWh you buy later. At July 1, 2026 standard-offer rates, a credit is worth about 24.68¢.
- The $27.37 monthly fixed charge stays on your bill; it already covers your first 50 kWh.
- Credits left after 12 months expire with no payment. Size the system to your last 12 bills.
Versant Power, Bangor Hydro District
- A credit is worth about 30.35¢ per kWh at July 1, 2026 rates, so the same system saves more than on CMP.
- The $22.41 monthly fixed charge stays and covers the first 100 kWh.
Versant Power, Maine Public District
- A credit is worth about 29.66¢ per kWh at July 1, 2026 rates.
- The $22.76 monthly fixed charge stays and covers the first 100 kWh.
Co-ops and town power districts
- They follow the same kWh-for-kWh credit rule, with a 100 kW system limit unless the utility allows more.
- Processes differ. Call the utility before you sign.
If you buy power from a competitive supplier
- The standard offer must credit you. Other suppliers take part only if they agree to.
- Ask your supplier in writing before the system is switched on.
Check the company and its warranty
Three names can appear in one solar deal: the company that sells, the company that signs the contract and the licensed people who do the work. Check that they fit together.
- Contract company: look up its license on the Maine Electricians' Examining Board (Office of Professional and Occupational Regulation, OPOR). Maine licenses electricians as individuals; it has no company electrical license and no statewide home improvement contractor license.. The name must match your contract.
- Electrical connection: A master electrician is the licensed individual who may engage in the business of installing electrical equipment, and no electrical installation may be made unless the master or limited electrician doing it first gets a permit from the Board (https://www.maine.gov/pfr/professionallicensing/professions/electricians/faq). Ask who does it.
- Warranty documents: ask for the workmanship warranty, the roof coverage terms and each equipment warranty before you sign.
Before your first sales call, read questions to ask your solar installer and how to read a solar quote.
Compare your Maine quotes
Ask every company to quote the same basics. Then the differences you see are real.
From quote to permission to operate
Some steps overlap, and timing depends on your town, your utility and equipment supply. Ask each installer for a written schedule for your project.
Proposal and site check
The installer looks at your roof, shading and electrical panel and gives you a written proposal.
You and the installerDesign and applications
After you sign, the installer finishes the design and applies to your utility for the connection.
Installer; you sign the formsPermits and utility review
Your town or county reviews the building and electrical permits. The utility reviews the connection.
Permit office and utilityInstallation and inspection
The crew installs the system. A licensed electrician connects it, and the inspector checks the work.
Installer crew, electrician and inspectorPermission to operate
The utility approves the system and updates your meter if needed. Turn the system on only after this step.

How we rate Maine solar companies
Each company gets up to 100 points from facts anyone can check: its own website and Maine’s public license records, read October 14, 2026. Facts a company does not publish earn no points. No company pays for its rating, and we do not use customer star reviews.
- Licensing (30 points): an active state license, a licensed electrician and license numbers printed on its website.
- Warranty protection (35 points): workmanship warranty length, roof-penetration coverage in writing and any production guarantee.
- Local presence (15 points): an office in Maine and Maine named as a service area.
- Track record (10 points): years installing solar.
- Options (10 points): batteries and the number of ways to pay.
Stars: 85 points or more is 5 (Top-rated), 72 is 4.5 (Excellent), 60 is 4 (Very good), 45 is 3.5 (Good), below 45 is 3 (Average). We did not inspect installations, collect customer quotes or test customer service.
Maine solar company FAQs
How do I check a Maine solar installer?
Maine licenses electricians as people, not companies. Ask the installer which master electrician will pull your permit and for that person’s license number. Look it up in the state’s free license search under Electricians and confirm it is active. Then read the written workmanship warranty, including roof leaks, before you sign.
Does Maine still have net metering?
Yes. Homes with rooftop or backyard systems get one kWh credit for each kWh they send out, at the full price they pay. Maine closed the program to new large projects on the utility’s side of the meter after December 31, 2025. Unused credits expire after 12 months, and fixed monthly charges stay.
Will solar raise my Maine property tax?
Not if you apply. Maine exempts the value solar equipment adds to your home. Give the Application for Renewable Energy Equipment Exemption to your town assessor by April 1 of the first year, and the system must be running on that date. You file again only if you sell or change the equipment.
Can I still get the federal solar tax credit in Maine?
Not for a system you own. The 30% homeowner credit ended for systems finished after December 31, 2025, and Maine has no state solar tax credit or rebate. With a lease or PPA, the company that owns the system can claim a commercial credit and may pass part of it to you.
Will the companies on this page contact me?
Not because they appear here. This page is an editorial comparison. If you request quotes, the providers that serve your area may contact you. They can include installers, marketplaces and lead exchanges. Our page on how we make money explains how EcoGen is paid.
