TL;DR
Julián Caro Linares created an open-source smart solar panel system that you can 3D print and build yourself, using the Arduino® UNO™ Q board. This project not only teaches you about solar energy but also provides a hands-on learning experience. The system includes two servo motors to adjust the solar panel's orientation for optimal sun exposure, and it features a live dashboard that displays real-time energy readings, weather data, and other metrics.
