Impact of Irradiance and Temperature on Electrical Parameters of Polycrystalline Photovoltaic Module: A Five Parameter Analysis

Abstract

In the current era, adopting renewable energy is not just a choice but a necessity. The role of photovoltaic modules significantly influences this shift from conventional energy sources. The performance and parameters of these PV cells are greatly affected by both irradiance and temperature. While the standard test condition assumes 1000 watts/m² and 25°C temperature, the reality of solar geometry often alters these values, leading to changes in the electrical parameters of the PV cell. This study, which employs a five-parameter single-diode model, is of paramount importance in understanding the impact of irradiance and temperature. The parameters are extracted from the P-V and I-V curves of the simulated solar cell and matched with data from the TP300 series polycrystalline TATA Power solar module. The analysis across various temperature and irradiance levels providescrucial insights into changes in shunt and series resistance, diodeideality factor, reverse saturation current, and photo-generatedcurrent. This investigation is vital in understanding howparameter alterations correlate with changes in solar cell performance. The study uses the MATLAB Simulink platform,utilizing data from the TATA solar module TP-300 seriesdatasheet.
