Free online course Solar Photovoltaic System Basics

About the free online course

Step into one of the fastest-growing areas of electrical work by learning the core concepts behind solar photovoltaic (PV) systems. This free online course gives you a clear, practical foundation for understanding how sunlight becomes usable electricity, so you can communicate confidently on the job site, support PV projects, or prepare for more advanced training in renewable energy.

You will explore what a solar cell does inside a PV system and why efficiency matters in real installations. Instead of treating efficiency as a buzzword, you will connect typical market ranges to expectations about performance, output, and design decisions. You will also build familiarity with common electrical terms used in PV discussions, including open-circuit voltage, and understand why these measurements matter for safety, equipment selection, and troubleshooting.

A key part of PV systems is converting DC power into AC power that buildings and the grid can use. You will learn the primary purpose of the inverter and where it fits within the broader system. By tying together cells, modules, and power conversion, the course helps you see how the main components work as a complete pathway from energy capture to usable electrical supply.

Designed for learners pursuing professional skills in the electrician track, the course uses short knowledge checks to reinforce what you learn and help you retain important definitions and functions. By the end, you will have a strong conceptual map of PV system basics that supports better decision-making, clearer communication with contractors and clients, and a smoother transition into hands-on solar work.
