The federal residential tax credit is dead in 2026. State incentive programs — from NJ SuSI ($90/MWh for 15 years) to MA SMART (monthly bill credits) — are now the main way to reduce your solar cost.

Federal Credit: Not Available for Homeowners
Section 25D (the Residential Clean Energy Credit) expired December 31, 2025. Homeowners in Maine who purchase solar with cash or a loan receive $0 in federal tax credits in 2026. Only third-party owned systems (lease/PPA) qualify for the 30% commercial ITC under Section 48/48E.
