Offset Your Costs with Solar Rebates and Incentives. Solar energy is environmentally friendly, free and almost inexhaustible. That’s why federal, local and state governments have tax credits and solar rebates for families that install residential solar systems. The incentives can substantially offset the cost of purchasing and installing a solar energy system in Marshalltown.
