Desarrollo de un dispositivo de rastreo solar de doble eje para acoplamiento en paneles fotovoltaicos

Abstract

The objective of this project is to create a two-axis solar tracker that helps improve the energy production of a solar panels. To achieve this, the system constantly adjusts the position of the panel so that it is always facing the sun. This design seeks to be more efficient than fixed systems. It has a mechanism that allows the panel to be moved precisely, rotating up to 180° horizontally (azimuth) and up to 90° vertically. To make the prototype, a combination of hardware and software was used. An ESP32 Dev Module microcontroller, four sensors with photoresistors to measure sunlight, and an FZ0430 voltage sensor to monitor the performance of the solar panel were used. The solution offers connectivity through IoT and the Arduino cloud, the graphical interface in Python that allows monitoring the process and seeing how the tracker follows the sun, sending alarms through the interface.
