The Town of Henlopen Acres in Delaware only permits roof-mounted solar panels/collectors to be installed and used on any principal structure. These panels are subject to any applicable building code, “including but not limited to the International Residential Code, Section M2301 and approved by the Environmental Review Committee (ERC).” The Town sets forth certain regulations for solar panels such as prohibiting the panels from being installed on the roof surface facing the street and requiring they be parallel to and not higher than six inches from the roofline or flush with the roof covering. The regulations also include factors that the ERC may consider in its review of any application for solar panels including the location of the panels; the concealment of supportive fixtures; and the aggregate size or coverage or the total number of panels.
