Abstract: The present invention relates to an intelligent performance ranking method for evaluating and comparing grid-connected photovoltaic (PV) module technologies under varying environmental and operational conditions. The method integrates fuzzy membership functions with graph-theoretic analysis using Seidel Laplacian Energy to provide a comprehensive performance assessment. Operational parameters including solar irradiation, ambient temperature, module temperature, output voltage, output current, instantaneous power, inverter efficiency, and energy generation are continuously monitored from a grid-connected PV system. The acquired parameters are transformed into fuzzy membership values representing different levels of operational performance and uncertainty. A graph representation of the PV system is subsequently constructed, from which a Seidel matrix and Seidel Laplacian matrix are derived and their corresponding eigenvalues are determined to calculate the Seidel Laplacian Energy. The fuzzy membership values are calculated and Seidel Laplacian Energy are integrated into an intelligent performance ranking index for comparative evaluation of different PV module technologies over monthly operating periods. The method accounts for environmental variations, operational uncertainty, electrical performance, and system connectivity, thereby enabling identification of the consistently better-performing photovoltaic technology and supporting technology selection, performance monitoring, predictive maintenance, and PV system.
