Solar Licensing Database

National Solar Licensing Database

With the tremendous growth of solar installations and the continuing evolution of licensing requirements for photovoltaic and solar installers, IREC’s National Solar Licensing Database provides information and references to the licensing, certification, and other requirements impacting the solar industry. This comprehensive tool is designed for policymakers, stakeholders, practitioners, students, consumers, and anyone looking for solar licensing information in the United States.

States establish licensing requirements for contractors to protect consumers from unsafe practices and to ensure systems are installed properly. As these requirements continue to develop and evolve, researching state-specific information can sometimes be complicated and time-consuming. IREC has done the work for you in the National Solar Licensing Database.

While IREC does review and update the information in the directory periodically, it cannot guarantee its accuracy. Users should always confirm requirements with their own state or local licensing board.
