Course Description: This 16-hour course teaches the step-by-step process of designing grid-tied and battery-based PV systems. Participants will explore sizing strategies, select appropriate equipment for each system type, identify mounting methods and related equipment needed for a safe and structurally sound installation, and calculate voltage, current, and power of the system to ensure its safe operation and code-compliant electrical installation.   

Design parameters of PV modules, inverters, charge controllers, batteries, and module-level power electronics (MLPE) will be discussed at length, and emphasis is placed on series and parallel circuit calculations, the I-V curve, maximum power point (MPP) tracking and the effect irradiance and temperature has voltage and current values in a PV system and its overall performance. Participants will be introduced to a variety of national and local building codes, electrical codes, and safety regulations as they pertain to PV system installation, interconnection, and inspection.  

Students can work through recorded presentations and exercises at their own pace. If the coursework is finished within 60 days and all assignments receive a passing grade, a completion certificate is issued.
