Dual Axis Solar Tracking System

Abstract

This is a project of DUAL AXIS SOLAR TRACKING SYSTEM. The project is about making two axis solar panel tracker that can be working robotic system. The Solar Tracker is a device which follows the movement of the sun. we used four LDR (Light Dependent Resistor). They are light sensitive devices. They are also called as photo conductors. The working principle of an LDR is photo conductivity, that is nothing but an optical phenomenon. When the light is absorbed by the material then the conductivity of the material reduces. We use two servo motor. Servos are controlled by sending an electrical pulse of variable width. A servo motor can usually only turn 90° in either direction for a total of 180° movement. we use to PIC16F877 microcontroller. The microcontroller is there for controlling automatically. We use 7805 regulator IC, 10uF capacitor (6pcs), 100uF capacitor 1pcs. We use LCD (Liquid Crystal Display) display. The layers are made of liquid crystals which have the ability to change the direction of their polarization when a voltage is applied to them. This creates an area which looks dark. Different areas are controlled by voltages from whatever circuitry controls the device. We used solar panel, 1N4007 diode, 1N4007 diode. The microcontroller is there for programming language C++. The main objectives of this project are to investigate a newly
