What incentives are still available—and how much can you actually save?
While some federal incentives changed recently, solar in Maine still offers strong long-term savings through net energy billing credits, property tax exemptions, and alternative financing incentives that can significantly reduce your energy costs over time.
This guide explains exactly what incentives are available in Maine right now and how homeowners can take advantage of them.
Here are the main solar incentives currently available in Maine:
✔ Net Energy Billing (NEB)
✔ Property tax exemption for solar equipment

Net Energy Billing (Maine’s Most Valuable Solar Incentive)The biggest solar benefit available in Maine today is Net Energy Billing (NEB).
This program allows homeowners to receive electricity bill credits for the extra solar energy their system produces and sends back to the grid.
Here’s how it works:
For many homeowners, this creates a near 1-to-1 energy offset potential, meaning your system can dramatically reduce or even eliminate portions of your monthly electric bill.
This is the foundation of solar savings in Maine.
One of the most valuable incentives many homeowners overlook:
Solar installations in Maine qualify for a statewide property tax exemption.
That means:
Installing solar panels typically does not increase your property tax assessment, even though it increases your home’s value.
Over time, this exemption alone can save homeowners thousands of dollars.
Solar equipment purchases in Maine may qualify for a sales tax exemption in many installations, reducing upfront system costs further, depending on equipment structure and installation details.
Your installer can confirm eligibility during your quote process.
Many homeowners still ask about the 30% federal solar tax credit.
As of 2026:
The traditional residential federal solar tax credit (Section 25D) expired for systems placed in service after December 31, 2025.
However:
Some solar financing structures still allow access to similar savings through third-party ownership models, where providers can apply commercial solar tax credits and pass savings to homeowners through lower payments.
This means incentives may still be available depending on how your system is installed.
Even though some incentives have changed, several important factors still make solar attractive:
Many Maine homeowners install solar specifically to stabilize long-term household energy expenses for the next 25+ years.
Savings depend on several factors:
However, homeowners with moderate to high electric bills often see meaningful reductions in monthly energy costs once their system is installed and producing power.
Energy policy evolves over time, but Net Energy Billing remains the primary incentive supporting residential solar installations across the state today.
Homeowners who install earlier typically benefit sooner from:
Waiting can sometimes reduce long-term savings potential.
