Construction And Performance Test Of Dual Axis Solar Tracking System

Abstract

This is a project of DUAL AXIS SOLAR PANEL 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 ATMEGA328P microcontroller. The microcontroller is there for controlling automatically. The main objective of our project is to utilize the maximum solar energy through solar panel. The solar panel tracks the sun from east to west automatically for maximum intensity of light also ensure that the tracking system design and components are cost-effective, making it a viable option for both residential and commercial solar installations. After testing and result we get that dual-axis solar tracking systems generate on average 15-30% more energy compared to static systems.
