PVOL101: Solar Training - Solar Electric Design and Installation (Grid-Direct) - Online

PVOL101 is your gateway to a career in the solar industry.  It all starts with the fundamentals, and a solid understanding of various components, system architectures, and applications for PV systems.  Other topics include site analysis, system sizing, array configuration, and performance estimation; electrical design characteristics such as wiring, overcurrent protection, and grounding; a detailed look at module and inverter specifications and characteristics; mounting methods for various roof structures and ground-mounts; and an introduction to safely and effectively commissioning grid-direct PV systems.  This course focuses on grid-direct PV systems, but covers material critical to understanding all types of PV systems.  These core concepts are expanded on in SEI’s upper ­level PV courses.
