The tax credit is gone.
The 30% federal credit for homeowner-owned systems ended after 2025. Any quote that still subtracts it is wrong.
For years, the easiest way to make a solar quote look cheap was to subtract 30% for the federal tax credit. For homeowners who buy their system, that credit is over.
What changed
The Residential Clean Energy Credit (Section 25D) no longer applies to expenditures made after December 31, 2025.[1] A system you buy and install today does not get it.
Where you will still see it
Old sales decks, savings calculators that have not been updated, and some salespeople who would rather not mention it. If a quote shows a "net cost after federal credit," ask which credit and which tax year.
What happens with leases?
Leases and power purchase agreements are different: the company that owns the panels may still claim business credits. That can make a lease look cheaper on paper. It does not make it cheaper for you unless the savings are actually passed through, in writing.
What we show
The prices on this site never subtract the federal credit. The only incentives we take off are state and utility programs that are open, and each one shows the date we last checked it.
