Automatic Solar Tracking System using MPPT and Mirror Booster

Abstract: This paper is to design and develop a newmicrocontroller based solar tracking system with a mirror booster based on MPPT. Solar energy is rapidly becoming analternative means of electrical source all over the world and thesolar energy becomes profitable when the solar rays are trackedwith its maximum efficiency. The best to get the maximumpower output of solar array is by sun tracking. This paperdeals with the design and construction of solar tracking systemby using LDR, PIC16F877A, Johnson motor, gear motor andmirror. Mirror is used as booster to maximize the efficiency. Thepanel and mirror will travel from south to north and vice-versa.The prototype is considered around a programmed pic16F877Awhich controls the system by communicating with sensors andmotor driver based on movement of the sun. The performanceand characteristics of the solar tracker are experimentallyanalyzed.
