MPPT Using P&O and IC Based PI Controller for Solar PV System with Charge Controller

The power output of the solar PV system depends mainly on the two variables such as temperature and irradiance. A technique for the effective use of solar PV is known as the MPPT. This technique extracts the highest available energy from the solar PV panel by enabling it to operate at the maximum effective output. This paper introduces 2 MPPT controllers that are standard Perturb & Observe (P&O) and Proportional Integral (PI). In specific, the performance of the controllers under two conditions is analyzed such as constant irradiation and different temperatures, constant temperature and different irradiations. The simulation work is carried out under MATLAB/SIMULINK, environment.
