Does a solar contractor need a license?
In states that do not require solar contractor licensing, certification can provide a baseline level of quality. State licensing may be restrictive, as state licenses do not typically transfer, so geographic mobility is limited.
How many states have solar contractor licensing requirements?
Currently, 12 states and Puerto Rico have solar contractor licensing requirements. The contractor licensing requirements described here refer to solar-specific licensing requirements, rather than general electrical or plumbing contractor licenses.
Who certifies solar power?
The Solar Rating Certification Corporation or SRCC is another leading certifier. The following states require a dedicated certification by either the NABCEP, SRCC, or, in some cases, other agencies: At present, there are still states that do not have dedicated solar licensing requirements.
Do I need a NABCEP certification to be a solar contractor?
In Utah and Rhode Island, NABCEP-certification is a prerequisite for qualifying for a state solar contractor license. In the absence of state licensing or certification requirements, local governments like counties or cities may adopt regulations or establish their own licensing procedure.
