Solar Tracker Implementation Using Matlab/Simulink

In this paper we present a mathematical modeling of photovoltaic module and a complete simulation of Solar Power Tracker and by using them on MATLAB Simulink we obtain V-I and P-V characteristics of PV module. The V-I and P-V characteristics are obtained for constant temperature at various solar irradiations. In this paper we also present a concept of Sensor array based solar maximum rays point tracking and motion of the solar panel accordingly. Microcontroller based control system design is developed to track the sun position. IndexTerms – Solar Tracker, MPPT, Stepper Motor, Solar Panel.
