Comparative Analysis of Fixed, Single and Dual Axis Solar Tracking System

The generation of power from the reduction of fossil fuels is the biggest challenge for the next half century.The idea of converting solar energy into electrical energy using photovoltaic panels holds its place in the front row compared to other renewable sources.But the continuous change relative angle of the sun with reference to the earth reduces the watts delivered by solar panel.This paper presents the implementation of a system that ensures a perpendicular profile of a solar panel with the sun in order to extract maximum energy falling on it.The unique feature of the proposed system is that instead of taking the earth as its reference, it takes guiding source.Solar trackers move the payload towards the sun throughout the day.The light dependent resistors do the job of sensing the change in the position of the sun which is dealt by the respective change in the solar panels position by switching on and off the geared motor the control circuit does the job of fetching the input from the sensor and gives command to the motor to run in order to tackle the change in the position of the sun.
