This Introduction to Solar Photovoltaic webinar provides a comprehensive understanding of small size solar photovoltaic systems, referred to as residential systems. The basic electrical principles as they apply to photovoltaic systems are reviewed, and the fundamental solar energy concepts explored. The course explains basic installation methods for both grid-tied and stand-alone photovoltaic systems, and thoroughly describes the components used for their construction. Students will learn how to correctly size each part taking into account load, budget, system geographical location, and National Electric Code requirements. Troubleshooting practices as well as safety rules while working around a residential photovoltaic system are also introduced.
