Solar power in Delaware

Solar power in Delaware was supported by a 30% federal tax credit, available through 2016. 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.[1] 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.[2]

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.[3]
