Pengembangan Aplikasi Android Auto Solar Tracking System Berbasis IoT pada Inovasi Pembangkit Listrik Solar Cell

Abstract

Additional electrical energy is needed for the development of contemporary times. After absorbing sunlight, solar cells generate electrical energy. This enables solar cells to produce more electrical energy for daily life. It is challenging to determine the amount of energy that can be generated, and the changing direction of sunlight makes it difficult for solar cells to fully absorb light energy. To overcome this issue, an application for Android-based smartphones is being developed to control and track solar cells. This application is designed to allow remote monitoring and control with a relay on the solar panel, which generates voltage, current, and power for the application. The application's display data is accessed via the internet through the Firebase database, transmitted through a microcontroller device using ESP32. The data shows voltage, current, and power, as well as the direction of the sun to ensure optimal voltage for the solar cell.
