Launched in 2009, the U.S. Department of Energy established the Solar Instructor Training Network (SITN), composed of nine Regional Training Providers (RTPs) to help fulfill a critical need for high-quality, local, and accessible training in solar system design, installation, sales, and inspection through train-the-trainer programs.  The nine RTPs are well-established solar training institutions that offer expert trainers and first-class training facilities across the U.S.  
 
As National Administrator for the SITN, the Interstate Renewable Energy Council (IREC) works closely with the RTPs, supporting a well-trained, highly-qualified solar energy workforce of sufficient size and diversity to meet the projected needs in the U.S.
