Sistem Penggerak Panel Surya Dual Axis Berbasis Microcontroller Untuk Optimasi Konversi Energi Matahari

Abstract

The purpose of this research is to design and construct dual axis solar panel tracker that can convert sunlight into electrical energy. Dual axis tracking sytem in this research used four LDR, Arduino Uno microcontroller, and servo motor. Four LDR functions as a direction of motion sensors . Servo motor is used to drive the solar panels with two degrees of freedom (Azimuth and Altitude). Arduino Uno microcontroller functions as a storage logic commands on the system drive. Prototype solar panels were designed to be able to follow the movement direction of the sun. The results showed that a dynamic solar panels converting sunlight into electrical energy more efficiently compared to static solar panels. This is because the largest energy received by the solar panel obtained when the sun radiation is perpendicular to solar panels. The surplus energy to the solar panel is 42.6%
