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 the federal 30% Investment Tax Credit make solar an increasingly attractive investment 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.
