In most U.S. jurisdictions, contractor licensing laws and building codes require certain electrical work only may be performed by qualified electricians. Rooftop solar projects always require building interconnections and wiring tasks, as well as connections to energy storage systems or the local power grid. Most of this work falls under the jurisdiction of qualified electricians. Roofing professionals who install or oversee rooftop solar installations should ensure they do not perform electrical work they are not qualified to do. Instead, roofing professionals should hire qualified electricians to do this work.
