Iowa 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.

Iowa state programs

Iowa's Solar Energy System Tax Credit provides 15% of the federal ITC amount as an additional state credit (effectively up to 4.5% of system cost, capped at $5,000). Iowa also has net metering requirements and a strong wind energy infrastructure that supports broader renewable adoption.
