Although PV Solar Electric Installers are not regulated in Colorado, some stakeholders argue that PV solar electric system installation falls under the electricians scope of practice.  Thus, these stakeholders see no need for new regulation.  In order to understand the relationship between PV solar electric system installation and the work of licensed electricians, a summary of the licensing requirements and the scope of practice of licensed electricians in Colorado follows.  
 
Electricians are regulated by the State Electrical Board (Board). The Board is made up of nine members consisting of two electrical contractors who have  master’s licenses; two master or journeyman electricians who are not electrical contractors; two representatives of private, municipal, or cooperative electrical utilities rendering electric service to the public; one building official from a political subdivision of the state that performs electrical inspections; one general contractor from the building industry; and one public member. The Board is located in the Colorado Department of Regulatory Agencies, Division of Registrations.

Utah's Division of Occupational and Professional Licensing requires installers of solar energy systems to be licensed contractors. The Division has established the contractor’s license classifications S202 - Solar Photovoltaic Contractor, and S215 - Solar Thermal Systems Contractor. A Solar Photovoltaic Contractor is licensed for the fabrication, construction, installation, and repair of photovoltaic cell panels and related components including battery storage systems, distribution panels, switch gear, electrical wires, inverters, and other electrical apparatus for solar photovoltaic systems.
