Delaware Net Metering

Delaware has 10 out of 11 electricity providers reporting that they offer net metering to residents with personal solar panels. At the state level, Delaware has highly favorable laws for consumers interested in investing in personal solar.

Energy Loss

There are 6 providers in Delaware that reported energy loss, including Delmarva Power, Delaware Electric Coop, and City of Dover Electric Utilities. Combined, these 6 providers average an annual energy loss of 5.74% of electricity generated. The US average is 2.76%, resulting in Delaware having a rank of 5th best in the US for energy loss efficiency.

Solar Taxes And Rebates

Motivating private citizens to consider installing solar panels can definitely be a challenge due to prohibitive initial costs. Governments can help the cause by passing legislation for tax breaks and rebates for those who purchase solar panels. Delaware currently does not offer a state tax credit for solar panel installation at a private residence. The state has rebates of $500 or less available to most citizens who wish to purchase private solar. Delaware offers no property tax exemptions to homeowners who purchase solar. The state provides a 100% sales tax exemption to anyone who install solar panels. This is a win for people in the state.

State Level Initiatives

Consumers seeking electricity plans that use renewable fuels will benefit from statewide legislation that encourage green energy usage. States that have Renewable Portfolio Standards (RPS) have requirements in place for all electric providers who sell electricity in the state. These standards require that a percentage of electricity must be generated from renewable energy. While further enhancements could be made, Delaware makes it necessary for 1-15% of electric production to come from renewable fuels. Also, there are currently no low income solar programs to encourage low income families to install solar panels.
