Wilmington averages 4.3 peak sun hours a day. A well-oriented kilowatt of panels produces roughly 1,255 kilowatt-hours a year here. A typical 9 kW residential system therefore produces around 11,295 kWh annually. At Delmarva Power’s rate of supply 12.09¢, that production is worth roughly $1,365 a year before any incentive.
Those are pre-shading numbers. Trees, roof pitch and orientation move them, sometimes a lot, which is why an installer looks at your specific roof rather than quoting from a city average.

Delaware's Green Energy Program has historically provided grants for residential solar, the state has an active SREC market, and net metering is available through utilities like Delmarva Power and Delaware Electric Cooperative. Net metering credits you for the surplus solar power your system sends to the grid: when your panels make more than you use, you bank a credit; at night you draw it back — for a lower, more predictable monthly bill.
In Delaware, net metering runs through utilities like Delmarva Power and Delaware Electric Cooperative. Full detail on our Delaware solar page, or learn why your bill keeps rising.
