Delaware State Solar Overview
Despite its small size, Delaware continues to increase its solar capacity at a rapid pace. It is not one of the sunnier states, but strong solar policies are driving the industry. The state’s renewable portfolio standard (RPS) has set a target of achieving 25% of its power from renewables by 2026, with 3.5% required to come from solar. In addition, the state’s net metering law allows third-party solar financing and shared solar, supporting the distributed solar market.
