Solar & Net Metering Policy
Net metering is available in Iowa, allowing solar owners to send excess electricity back to the grid and receive credits on their utility bill. IOUs must offer net billing/metering. Excess generation usually carries over at retail rate up to a cap, then avoided cost. Iowa does not currently offer a state solar tax credit, though the federal 30% ITC still applies to qualifying installations. Additional savings are available through a property tax exemption on the added home value and a sales tax exemption on solar equipment.
