Abstract

The effectiveness and accuracy of two different MPPT methods of solar photovoltaic (PV), namely Perturb & Observe (P&O) and Constant Current (CC) have been investigated in this study. The main objective of this study is to test the impacts of temperature and solar irradiance (insolation) variations on solar PV output power which are achieved through these methods. Usually, solar insolation and temperature are the two most important influencing factors that have a significant impact on the output power (Pout). Here, the two conventional MPPT techniques have been applied to analyze the response through power characteristics curves of solar PV systems subject to changing environmental conditions. The MPPT techniques have been implemented on the solar PV system using MATLAB®. Additionally, the output power curves at various irradiances are shown in this work. The research demonstrates that the P&O-based MPPT method outperforms the CC-based MPPT method.
