Once you understand what a solar panel does, the next question is how a whole system goes together. Solar Energy and Photovoltaic System Technologies is the free course that answers it. It runs about 3 to 4 hours at the intermediate level, so it fits best after you have the basics down, and it costs nothing to take.
This one gets practical about the parts of a real grid-connected setup. You learn to identify the components of a photovoltaic system, tell inverter types apart, understand ground mounting structures, and grasp DC and AC disconnects. It also covers how batteries fit into a home setup, how to choose battery storage, and what to weigh when adding a solar thermal system.
Straight talk: this is a planning and knowledge course, not a license to wire your own service panel. Real installs are governed by code and local rules for good reason. Treat this as the course that lets you size a system, talk to an installer as an equal, and know which pieces are genuinely yours to handle. If the components are still new to you, start with the beginner solar course on our Free Shelf first.
What you will learn
- The components of a grid-connected photovoltaic system
- How inverter types differ and where each fits
- Ground mounting structures and DC and AC disconnects
- How to choose battery storage for a home
What the course walks you through
- See the system: identify every major component and what it does.
- Pick the inverter: understand the inverter choices for a home setup.
- Mount and disconnect: ground structures and the safety disconnects that matter.
- Store the power: how batteries work in a house and how to choose storage.
The course is free to complete. A certificate is available at the end that you can add to your resume or LinkedIn, and proof of practical solar knowledge can help you get hired or ask for a raise with something concrete to point to. You are never required to buy it to finish the lessons.
A system you understand is a system you can plan, price, and maintain with confidence. This course gives you that footing for a grid-tied solar setup.
