Abstract: The rapid integration of solar photovoltaic (PV) systems into the global energy landscape necessitates the development of accurate predictive models for PV system performance. A solar photovoltaic (PV) system is modelled either by its equivalent single-diode, double-diode or multiple-diode model. The model equations of these models need to be solved through iterative process which sometimes may not suitable for analysis. One cannot analyse a system using modal analysis, state-space analysis, linearisation, etc., when an iterative process is involved. Therefore, this paper suggests a multivariate regression based novel function of solar PV which replicates the actual PV system model. The model incorporates key factors such as solar irradiance, temperature, and system configuration to provide a comprehensive understanding of PV system behaviour. The proposed regressed model of the solar PV has been tested under various operating conditions and realistic solar data. To validate the accuracy and robustness of our multivariate regression model function, a feedforward back-propagation neural network has been used considering the data generated by the proposed regression model. It was also observed that the proposed model is good enough for the mathematical analysis of the PV integrated systems.
