Topics covered by the NJATC five-day Train-the-Trainer course, Installing Grid-Connected Photovoltaic Systems, include: radiation and site assessment, solar array orientation, electrical properties, mechanical design, inverter operation, inverter configuration, array performance guidelines, conductor sizing, over-current protection, and identification of disconnect means. Students also examine the financial incentives, advantages and disadvantages of applying solar photovoltaics.

The goal of the NJATC solar program is to aid in the development of system-knowledgeable professionals to help ensure the safety and quality of PV electric system installations. The course includes both classroom instruction and hands-on experience in designing, installing and commissioning grid-connected PV systems. An emphasis is placed on National Electrical Code compliance and accepted state-of-the-art industry design and installation practice. Prerequisites for the course include a fundamental understanding of electrical systems, their properties and terminology, according to Todd Stafford, NJATC director of Instrumentation, Distributed Control and Solar Photovoltaics Curriculum Development and Training.
