PORTLAND PRESS HERALD • July 10, 2025
With the sudden end of a long-standing federal tax credit for residential solar projects in sight, Maine’s solar installation companies are bracing for a short surge in demand followed by a long stretch of uncertainty. The residential clean energy credit, sometimes referred to as the 25D solar credit, offers homeowners a federal tax credit worth 30% of the cost of a new solar system. Depending on the project, that credit can be worth a five-figure sum. But the federal reconciliation bill, which President Donald Trump signed at an Independence Day picnic, ends eligibility for any expenses made after Dec. 31, several years earlier than was previously planned. That’s left some companies scrambling to plan past six months from now.
