Delaware offers no property tax exemptions to homeowners who purchase solar panels. There is currently a 100% sales tax exemption in place for the purchase of private solar panels at a place of residence.

State Level Initiatives

Consumers who are shopping for electricity plans that use renewable sources will have much better luck if there are state level initiatives that encourage green energy usage. Many states require renewable fuels to make up a percentage of the fuel used for electricity generation by electricity companies in the state. These requirements are referred to as Renewable Portfolio Standards (RPS). While further improvements could be made, Delaware makes it necessary for 1-15% of electricity generation to come from renewable fuel sources. In addition, the state does not have any sort of low income solar programs that assist with the installation of solar panels at low income households.
