Question 1

Is solar worth it in Maine in 2026 without the federal tax credit?

Accepted Answer

While the federal 25D tax credit for homeowners expired in July 2025, solar panels in Maine remain worth it due to high utility rates and 1:1 Net Energy Billing (NEB).

Question 2

How much do solar panels cost in Maine in 2026?

Accepted Answer

The average cost is between $2.91 and $3.19 per watt. A typical 9 kW system costs approximately $27,450 before state tax exemptions.

Question 3

What are the remaining tax benefits in Maine?

Accepted Answer

Maine offers a 100% property tax exemption statewide and a 5.5% sales tax exemption on all solar equipment and installation labor.

Question 4

How does Net Energy Billing (NEB) work in 2026?

Accepted Answer

Maine still offers 1:1 retail rate credits for rooftop solar, allowing you to bank 100% of the excess energy you send to the grid.

Question 5

Can I still get a 30% credit through a Lease or PPA?

Accepted Answer

Yes. Because the financing company claims the Section 48 commercial tax credit, homeowners who choose a Solar Lease or PPA still receive the 30% benefit passed through as a lower electricity rate.
