Federal (2026 update)

The 30% federal Residential Clean Energy Credit ended for systems placed in service after December 31, 2025. If you buy with cash or a loan in 2026, there's no federal credit. A lease or PPA can still capture a 30% commercial credit — worth roughly $5,033 on a typical Maine system — which the provider passes on through lower payments. More in our federal tax credit guide.

Net metering

How your utility credits exported solar is effectively an incentive too — and often worth more over time than a one-off rebate. See Maine net metering.

How to find everything you qualify for

  • Search the DSIRE database by your ZIP code.

  • Have installers itemize every incentive in their quote.
