Queens Rooftop Solar Interconnection Guide
Queens, New York property owners and installers must follow both City building permit rules and utility interconnection procedures to connect rooftop solar systems to the grid. This guide explains the practical steps: municipal permits and inspections administered by the NYC Department of Buildings, utility interconnection applications, compliance inspections, and final approval before you can operate parallel to the Con Edison network. Where agency pages do not state exact amounts or deadlines, the guide marks those items as not specified on the cited page; information is current as of February 2026.
