Delaware Statewide Solar Net-Metering Law

Delaware Code Title 26 § 1014 ("Public purpose programs and consumer education") is the statewide solar statute. It directs the Public Service Commission, municipal electric companies, and electric cooperatives to "promulgate rules and regulations that provide for net energy metering." Eligible residential solar systems are capped at "not more than 25 kW" and nonresidential systems at "not more than 2 megawatts per DP&L meter." Suppliers must credit monthly excess generation at the volumetric supply-service rate and "shall not charge a net-metering customer any stand-by fees or similar charges." There is no statewide solar-panel building permit; interconnection, sizing, and crediting run through this program and the Commission's rules.

A utility that denies eligible net metering, imposes stand-by fees, or applies discriminatory rate structures violates § 1014 and the Commission's net-metering rules, and is subject to Public Service Commission enforcement and corrective orders.
