Colorado issues licenses for electricians and plumbers at the state level. Colorado does not issue a contractor’s license specific to solar at the state level. However, there are local solar specific requirements in some counties (such as El Paso County). All contractors should check with the authority having jurisdiction for solar specific requirements.
All work performed on the AC side of the inverter must be done by an electrical contractor who employs a licensed journeyman electrician or a licensed residential wireman who will do the work.
