Different diode models comparison using Lambert W function for extracting maximum power fromBIPVmodules

Perfect modeling of the building-integrated photovoltaic (BIPV) module circuit equivalent is required for examining the operation of a BIPV system. Before designing the power electronic converters of an overall BIPV system, a perfect diode modeling is required that usually resembles theI-VandP-Vcharacteristics of the BIPV modules. In this research article, different types of diode modeling of BIPV systems along with their comparative analysis based on the Lambert W function in MATLAB/Simulink environment is presented. The main aim of this research article is to analyze Mprime transparent M 115-130P-FI BIPV modules (115 Wp and 130 Wp) and compare the existing diode models in terms of accuracy and extraction of unknown parameters for the same. Simulation results for Lambert W function based comparison of the five-parameter model (FPM), seven-parameter model (SPM) and nine-parameter model (NPM) power of 115 Wp and 130 Wp BIPV modules along with their percentage errors are well presented. Lambert W function based comparison of FPM, SPM, and NPM is further made at different values of irradiations and temperatures respectively.
