A finite element model of the photovoltaic module with different component parameters was established and Von Mises stress of crystalline cell was calculated using ANSYS software. The effects of wind pressure and shear modulus variation of EVA were taken into account in the analysis. The analysis results show that 1) the stress distribution in the cell agrees with the theoretical results(i.e., the maximum stress occurs at the center of the cell and the stress decreases nonlinearly toward the cell edges, and the stress in the cell increases nonlinearly with an increase of shear modulus of EVA); and 2) the composite layer that consists of EVA, cells, and TPT exhibits a little effect on the rigidity of the module, when it is subjected to wind loads and flexural deformation occurs approximately at the neutral surface of the panel.
