Commercial Solar in Delaware in 2026
Delaware's DNREC Green Energy Program provides cash grants for commercial solar installations that stack with the federal ITC. Delmarva Power commercial accounts benefit from above-average electricity rates and retail-rate net metering. Delaware SRECs trade on the active Mid-Atlantic PJM market, adding ongoing production income on top of electricity savings. The state's I-95 corridor between Wilmington and Dover has the densest commercial solar market. See DSIRE Delaware for all current incentive programs.
