Solar Panels in Maine

Maine residents across 91 towns and cities are served by 7 electric utilities, with residential rates ranging from 11.6¢ to 32.0¢ per kWh. The state average of 18.4¢/kWh is well above the national average of 16.8¢/kWh, making solar an especially strong financial investment. At this rate, a typical 8 kW solar system saves approximately $1,763 per year.

The federal residential solar tax credit (Section 25D) expired at the end of 2025. This means homeowners who buy solar with cash or a loan no longer receive a federal tax credit. State and utility-level rebates are now the primary way to reduce your solar investment. Third-party owned systems (leases and PPAs) still qualify for 30% under Section 48/48E.

100% of Maine utilities offer net metering, allowing solar homeowners to earn bill credits for excess energy.Browse the towns below to see exact rates, incentives, and savings estimates for your specific location.
