Federal solar tax credit in 2026
The residential ITC remains 30% through 2032 for systems you own (purchase or loan). On a $14,850 install in Louisiana, that is roughly $4,455 in tax credit value.
Leases and PPAs do not qualify — the installer keeps incentives. See our full ITC guide for claiming steps.
