Precised and Efficient Mobile Solar Tracking System with amicable power consumption

In recent days, solar energy utilization is becoming more over whelming in the generation of power. The power production is not efficient to meet the required standards. It is essential to improve the efficiency of PV solar modules using low power consuming solar tracking systems. This paper aims in designing a solar tracking system using pressurized nitrogen gas and programmable logic controller to control the motion of dual axis solar tracking surfaces. The tracking direction is based on the voltage differences of four middle edged differential amplifiers of the solar panel which is fed to the comparator and programmable logic controller. Solenoid valves are used to control the axis of the solar panel in that specified direction. This pressurized air controlled solar tracking system consumes very less power than the conventional method.
