Do I need a permit for solar panel installation in Centennial?
Yes. In Colorado, solar panel installation generally requires a permit, and Centennial is no exception.
Centennial requires a permit for residential rooftop solar, applied for through the Centennial Self-Service (CSS) portal, and the array must meet the 30 psf roof snow load Centennial enforces. Electrical work is reviewed under the 2020 NEC that Centennial has adopted, and the electrical contractor must be licensed through the Colorado State Electrical Board with Centennial's contemporaneous license review. Confirm current fire access pathway and rapid shutdown details with the Building Division before finalizing the layout. A rooftop solar install in Colorado typically needs both a local building permit for the mounting and a state electrical permit for the wiring; the electrical portion must be done by a state-licensed electrician or by the homeowner on their own residence. Snow-load and wind design for the array, plus a separate utility interconnection approval, apply; confirm the full set of approvals with your building department and utility before installing.
