Advanced PV Design
5-days
This course expands upon the Basic PV Design and Installtion Course, focusing on the National Electric Code (Tuition includes a current NEC Code Book). The curriculum includes grid interface calculations, grounding considerations and wire sizing. Participants evaluate system performance under various operating conditions. Commercial system design elements, including inter-row shading, inverter selection and data monitoring solutions are covered. Instructor lectures are combined with system design exercises. There is NO significant hands-on component. This Instructor-Led workshop consists of 5-days of classroom lecture combined with student exercises and participation.
Prerequisite: Participants must have completed the Basic PV Design & Installation course or have Instructor permission. This workshop fulfills the educational requirements for Category “B” of the NABCEP’s Solar Installer Certification. This course also helps you prepare for the NABCEP PV Entry Level “Certificate of Knowledge” exam. For exam information see: www.nabcep.org.
You will complete 32.5 cumulative hours of training that may be used toward NABCEP certification.
