How to Become a Solar Contractor

Commercial and residential solar is growing exponentially in locations across the country, leaving states to play catch-up as far as rolling out contractor requirements and qualifications.

More and more jurisdictions have started to define what it means to be a practicing solar installation professional, however the definitions vary by state - and often county to county.

What's often confused are the terms solar license and solar certification - and which is required? Learn more below.

Getting Started in the Solar Industry

First, you need to understand the difference between a solar license and a solar certification.


mandated by the state, for legal and liability purposes, to practice a profession or offer a service within an industry

  • legally recognized by your state
  • licensure requirements vary by state
  • typically involves passing a state exam
  • typically only recognized in your state
  • Certification

    awarded by a trade organization, such as NABCEP, that upholds best practices for solar professionals

  • typically not required by the state (voluntary)
  • shows compliance of accepted solar processes
  • must pass a third-party certification exam
  • recognized internationally & transferrable across states

    Common Pathways for Working in Solar

    There are three basic approaches for states to regulate solar installations, either through licensure or certification.

    1. No specific solar license

    Must be a licensed electrician (to install solar panels) or a licensed plumber (to install solar thermal)

    Down side: Electricians and plumbers with no experience in solar can complete installations, while installers with years of solar experience are barred from the trade. This option can be a barrier to entry-level contractors who want to install solar but are not licensed as an electrician or plumber.

    As a general rule, if a state does not have specific licensing requirements for solar installers, then it would fall back to general licensing requirements that would apply to all electrical work.

    2. Criteria for utility incentive programs

    Requires a solar installer to achieve professional certification as proof of their knowledge and skills

    Plus side: This approach opens a career pathway for individuals who want to become solar installers but are not licensed tradespeople. The North American Board of Certified Energy Practitioners (NABCEP) worked with industry experts to create a "Job Task Analysis" that defines the knowledge and skills for a solar installation professional. After passing the NABCEP exam and earning the certification, an individual can effectively advertise their expertise in the solar industry. Learn more about NABCEP Certification.

    3. Specific solar license

    When states identify specific requirements for a contractor to earn a license specializing in solar

    These licenses may be sub-classifications of an electrical or plumbing license and are typically defined to limit the scope of work to direct solar installations and maintenance tasks

    What's Required in My State?

    With how fast solar is growing, states haven't yet developed a standardized process for ushering in new solar professionals. The requirements vary by state, and sometimes county by county.

    For example, a solar contractor in...

    • State A may need an electrician's license
    • State B may need an electrician's license with a specialty license in solar
    • State C may need a general contractor's license
    • State D may not need a license but may need a NABCEP Certification
    • State E may need a NABCEP Certification to qualify for the license

    The best way to find out what's required in your area is to call your local utility or building department.
