Overview
Is Solar Worth It in Maine?
Maine may be one of the northernmost states in the country, but its solar market is growing rapidly. High electricity rates (averaging $0.18–$0.22/kWh), strong net metering laws, and state incentives including net metering and a property tax exemption make solar an increasingly attractive investment -- the federal 30% ITC expired Dec 31, 2025, but state programs remain strong for Maine homeowners.
Maine has been expanding its solar incentive programs, and the state's commitment to renewable energy -- including a goal of 80% renewable electricity by 2030 -- is driving continued growth in residential solar installations. Maine homeowners also benefit from a property tax exemption that prevents solar from increasing their tax bill.
