Delaware Solar Information

Delaware isn't a bad state for solar but far from the strongest. There is a state tax credit that reduces your income tax. Along with basically wiping out your state income tax although not required by the state the three major utilities servicing all of Delaware offer net metering. As always in Delaware you are entitled to the 30% federal tax credit.

Solar power in Delaware is small industry. Delaware had 97 MW of total installed capacity in 2016. The largest solar farms in the state included the 10 MW Dover Sun Park and the 12 MW Milford Solar Farm.

The expansion of Bruce A. Henry Solar Farm near Georgetown in Sussex County from 23 to 40 acres was completed in 2020.

In a 2012 study, a typical 5 kW system will pay for itself in five years, and go on to provide a savings of $37,837 over the balance of its 25-year life. It is estimated that 19% of all electricity use in Delaware can be provided by rooftop solar panels. The state's renewable portfolio standard requires 0.4% from solar in 2012, 0.6% in 2013, 3.5% from solar by 2025, and 25% from renewable sources.

Net metering is available for residential customers up to 25 kW and others from 100 kW to 2 MW depending on type of customer and the utility. Excess generation is credited at retail rate to next month's bill and optionally paid once a year at energy supply rate (normally referred to as "avoided cost"). Best practices recommend no limits, either individual or aggregate, and perpetual rollover of kilowatt credits, and not converting to a monetary value. Allowing optional payment once a year, either at avoided cost or retail, allows a mechanism of providing for the case where the system installed is larger than needed.

According to Delmarva Power & Light Co, we received the cost of kWH in your area and calculated energy consumption based on an average electricity bill for 3 months.
I am claiming the 30% Federal Tax Credit (ends 2019) i

When you install your solar system, 30% of your project expenses apply toward a credit to offset any taxes you owe that year. This federal tax credit is a major incentive to go solar, but it is being phased out by 2022.

Most people are eligible to claim this credit (you must owe federal taxes to be eligible).
