Photovoltaics (PV) or solar cells as they are often called, are semiconductor devices that convert sunlight into direct current (DC) electricity. Groups of PV cells are electrically configured into modules and arrays, which can be used to charge batteries, operate motors, and to power any number of electrical loads. With the appropriate power conversion equipment, PV systems can produce alternating current (AC) compatible with any conventional appliances, and can operate in parallel with, and interconnected to, the utility grid Course Description This 8-hour course uses a combination of lecture and classroom activities to teach the basics of photovoltaic (PV) systems. Participants will learn how PV systems work, diagram the four PV system types, describe and identify components, understand the best application and limitations of each system type, define the solar window, make energy efficiency recommendations, estimate system loads, and understand the basics of PV site assessment
