This report describes the process of building your own solar modules. The fabrication of solar modules requires the use of lamination technology, which is challenging for individuals and students. However, if we can establish the process of building the solar modules ourselves, we can obtain the modules with various specifications based on free ideas. The purpose of this work is to install the modules into the body of a solar car, and the contents of our practice are illustrated as an example. Furthermore, we also demonstrate that high-quality solar modules can be made relatively easily by high school students. Our results are expected to contribute to research and development including product development and related fields.
