Parameter extraction and estimation based on the PV panel outdoor performance using iterative method

M.H. Ali, A Yusuf

Abstract


This work presents a novel approach to predict the voltage-current (V-I) characteristics of a PV panel under varying weather conditions to estimate the PV parameters. Outdoor performance of the PV module (AP-PM-15) was carried out for several times. The experimental data obtained are validated and compared with the estimated results obtained through simulation based on the manufacture’s data sheet. The simulation is based on the Newton-Raphson iterative method in MATLAB environment. This approach aids the computation of the PV module’s parameters at any varying weather condition. The computed significant error indicates that the result has a good agreement with the experimental data.

Keywords: Newton-Raphson, Parameter extraction, Simulation, Photovoltaic, Relative error
