Design and Construction of Photovoltaic Charger Optimization Using Temperature Control Based on Proportional Integral Derivative Controller

Abstract

This research designs and builds a photovoltaic charging system optimized with temperature control using PID (Proportional Integral Derivative). This system aims to improve charging efficiency and extend service life by controlling the temperature that affects the performance of the photovoltaic charger. Solar cells are used to convert solar energy into electricity, which is then regulated by the solar charger controller before going to the battery. Arduino controls the temperature of the solar cell by activating the air pump based on the PID algorithm and displays temperature, voltage, and current data on the LCD. As a result, this system is able to improve charging efficiency and maintain the temperature within the desired limits, thereby extending the service life of the charger.
