Sunflower mimic robot for development of dual axis solar tracking system

Abstract

This Today's world depends upon utilization of some form of energy. Be it use of mobiles, vehicles, power supply in houses etc., everything functions on the basis of energy input. The use of energy derived from fossil fuels began in early 1800 and is used till date. In the current theme that calls for saving energy and reducing pollution, it’s undoubtedly of great significance to make full use of solar energy. The solar panel system sprouted with the use of a simple magnifying glass to concentrate solar energy which has now revolutionized by using a much higher solar panel system. The framework consists of webcam, electronic circuit, Microprocessor and two DC motors. This solar tracking system is autonomous, dual axis and hybrid type. This tracking system is camera-based and can track the sun continuously. By using Region of Interest algorithm, we can get the sun coordinates from the frame. These values are sent to the microcontroller to actuate the motors and reposition the panel. This framework works free of its primary settings and can be utilized in any geological area. It holds the solar panel opposite to illumination of sun to get the most extreme solar energy and hence produce most effective power yield for the duration of the day. This study yields an output of up to 2-3% increase from a stationary solar panel.
