Solar Electrical Install course by Interplay Learning Interactive Training

About this course

Step into one of the fastest-growing trades by learning how real solar electrical installations are put together, connected, and verified. This free online course is designed for anyone developing professional electrician skills and wanting practical confidence with PV system electrical work. You will focus on how each major component fits into the complete system so you can think like an installer on site, not just memorize terms.

Throughout the training, you will learn to recognize and explain the role of core hardware such as inverters, revenue grade meters, array junction boxes, and AC disconnects, and how they interact within a safe, code-minded electrical layout. You will practice reading solar electrical schematics so you can follow a circuit from the array to the inverter and onward to the point of interconnection. The goal is to help you interpret diagrams accurately and translate them into clean, logical field work.

You will also work through installation workflows that mirror what technicians do on rooftops and exterior walls: mounting equipment, planning conduit paths, making roof penetrations with best practices, setting appropriate spacing for supports, and pulling and organizing conductors for a professional finish. Just as important, the course reinforces careful termination techniques in the AC disconnect, the main service panel, and metering equipment, with a strong emphasis on why each step matters for safety and reliability.

To support real-world readiness, you will learn the purpose of lockout devices, how labeling prevents costly mistakes, and why electrical installs most often fail when details are skipped. By the end, you should be able to explain installation decisions, follow an organized sequence of work, and communicate clearly about what is happening electrically at each point in the system. Complete the activities to validate your understanding and, if available, earn a certificate to showcase your new solar electrical skills.
