The real cost of solar in Iowa

A typical 10 kW rooftop system in Iowa runs about $28,500 installed. The federal Residential Clean Energy Credit knocks 30% off — around $8,550 — bringing the net price to roughly $19,950.

Iowa adds its own incentive: State solar tax credit (limited funding). Stack that on top of the federal credit. Iowa also exempts the added home value from property tax.
