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.

The SolarEdge Safe Harbor: Delaware ITC Access Through 2030

The federal construction-start safe harbor deadline (July 4, 2026) has passed, and most developers are now racing to place projects in service by December 31, 2027 — the standard cutoff — or risk losing the ITC entirely. Our select installer network isn't on that clock. Through a pre-negotiated, physically verified equipment reservation with SolarEdge, our partners secured safe-harbored access to the federal Investment Tax Credit for qualifying Delaware projects completed by December 31, 2030 — a three-year extension unavailable to developers outside this network.

Deloitte independently reviewed the strategy: its team toured SolarEdge's manufacturing facility, met with SolarEdge leadership in Tampa, FL, and issued a memo confirming that projects built on this reserved-inverter methodology qualify for ITC treatment. SolarEdge has committed gigawatt-scale production capacity to this arrangement, with roughly 200 MW currently allocated to partner networks nationwide. Fewer than 10 installer networks in the US hold a direct reservation of this kind.
