Install Your Own Solar Power System by LRN2DIY

About this course

Learning to install a solar power system can feel out of reach if you have never worked with rooftop equipment or electrical components. This free online course is designed to close that gap by guiding you through the practical decisions and safety habits that matter when planning a DIY solar setup. You will gain confidence in how a residential system is put together, how to evaluate common options, and how to avoid expensive mistakes before you ever pick up a tool.

Rather than treating solar like a mystery, the course helps you think like an electrician: focusing on the purpose of each component and the real-world trade-offs. You will explore why many homeowners begin with a DIY solar kit provider to simplify design choices and purchasing, and how that approach can prepare you for working with an installer later if you decide not to complete everything on your own.

Safety is treated as a core skill, not an afterthought. You will practice the fundamentals of ladder safety and learn rules of thumb used on rooftops, including how proper placement affects stability and load. You will also look at roofing considerations such as the function of a solar deck, helping you understand what protects the roof while supporting long-term performance.

On the technical side, the course clarifies key system architecture decisions, including choosing between microinverters and string inverters and what that means for output, monitoring, and troubleshooting. Finally, you will learn how incentives influence project budgeting by calculating the estimated net cost of equipment after a federal tax credit, giving you a more realistic view of the investment and potential savings. By the end, you will have a clearer plan for building a reliable solar system and the know-how to communicate confidently with suppliers, inspectors, or installers.
