Delmarva Power Offers Incentives For Going Solar in Delaware

As if you needed another reason to go solar…

As part of Delaware’s Green Energy Program, the electric utility company Delmarva is offering incentives to get Delaware residents to invest in solar energy. These incentives consist of grants for residential, non-residential, and nonprofit customers who install solar panels on their property. The rebates are meant to offset the cost of installation and encourage residents to make a lifestyle change that will both benefit the entire community and save users in utility costs over time.

Delaware residents who opt to have a 50 kW photovoltaic (PV) system installed could receive a $15,000 rebate. Non-residential customers have a maximum rebate of $24,000, and non-profits that go solar could receive a $48,000 rebate. Additionally, these systems pay for themselves in decreased energy bills and increased home value.

Many of Delmarva’s competitors, such as DEMEC, have recently put their own grant programs on hold or ended them altogether, making Delmarva your prime choice for solar energy.

Learn more about applying for a grant with Delmarva Power.

In addition to these grants, you could be entitled to federal tax credits. Taxpayers can claim 30% of qualified expenditures for the system, including equipment and labor costs. Currently, there is no maximum credit for solar-electric systems installed before 2016. You can even apply any excess credits toward taxes the following year.  After combining these tax credits with Delmarva’s rebates, now is the best time to go solar in Delaware.

Delaware at the Forefront of Solar Policy


Over the past year, solar power has accounted for 48% of the new renewable energy installed in the United States.  However, policies like installation incentives and renewable energy standards vary widely from state to state.  These policies affect the behavior of both corporations and individuals and thus are vital to the widespread implementation of solar and other renewable energy sources.

In a recent evaluation of state-to-state differences in solar policies by, Delaware solar power policies ranked 4th in the nation for their more traditional solar installation subsidies as well as a other non-traditional solutions.

One of these innovative policies is Delaware’s Renewable Portfolio Standard (RPS).  After its most recent update in 2009, this policy requires that retail electricity suppliers buy 20% of their electricity from renewable sources by 202o (25% by 2025), with 2.25% of that coming from solar energy (3.5% by 2025).  Eligible renewable energies consist of solar electric, wind, ocean tidal, ocean thermal, fuel cells powered by renewable fuels, hydroelectric facilities, sustainable biomass, anaerobic digestion, and landfill gas.  However, solar electric is the only one on the list that was given a specified cut-out requirement.

If other states start to follow Delaware’s lead in terms of energy reform, the US can make a large dent in its dependence on fossil fuels and non-renewable energy.
