Navigasi Solar Cell

Abstract

The globalization demand in era for electricity is increasing, along with the development of information and technology world. While the fuel used to generate electricity is almost exhausted. So the people started to look for other energy to generate electricity, one of the solar cell. Using solar cell is better if the position perpendicular to the sun. In this final project designed a tool that serves movement of solar cell, in order to follow the direction the sun moves. Solar cell navigation was designed using a microcontroller as controller, DC motor as actuator and LDR as light sensor. Position control of navigation solar cell using PID controller. Solar cell navigation can following the direction of the sun, the solar cell navigation rotated in the opposite direction of the sun then navigate the solar cell to brighter light. Range of solar cell navigation angle between 40-140 degrees, but there is a lack of tools that can not be silent when it is perpendicular to the sun.
