Abstract The electrical parameter characteristics of flexible photovoltaic panels are significantly influenced by temperature changes, making it difficult for conventional ideal photovoltaic cell models to meet accuracy requirements. To explore the physical characteristics of flexible photovoltaic panels more accurately, this study adopts methods such as mathematical modeling, physical setup, data collection, and integrated statistical analysis. Using flexible photovoltaic panels as the subject of research, this paper combine theories of series and parallel circuits to construct a simulated circuit in the laboratory. Metal halide lamps are used to simulate sunlight, and real-time temperature data of each cell on the flexible photovoltaic panel is recorded under varying conditions of density, tilt angle, and curvature. These sets of data are then plotted to create curves that help analyze the temperature characteristics and variation patterns of the photovoltaic panels. Simultaneously, voltage and current parameters under the same curvature conditions are measured to analyze photovoltaic cells exposed to different light intensities, summarizing their physical parameter characteristics.

Key words： temperature characteristics flexible photovoltaic panels bending rate electrical parameters
