Louisiana solar incentives
Federal ITC — 30%
All US homeowners qualify for the 30% federal Investment Tax Credit through 2032. On a $27,000 system, that's a $8,100 dollar-for-dollar tax credit.
Louisiana state programs
Louisiana does not currently have an active solar tax credit. The previous Solar Energy Systems Tax Credit program ended in 2021. Louisiana's low electricity rates (among the cheapest in the US at under 10¢/kWh) mean longer payback periods, though the federal 30% ITC still applies to all installations.
