The supporting for PV modules is made of aluminum and will deform, and buckling due to the forces. In this article, the finite element program Abaqus, is used to build the model for numerical analysis. In order to understand the deformation modes and the stress distribution of the aluminum frame in different conditions, different aluminum section types, frame heights, contact frictions, different specification loading and mounting methods are considered. According to the preliminary analysis of the loading behavior and the slipping distance. In the conclusion, we recommend better frame structure and mounting method. Then the location of module deformation, the damaged area and where the maximum stress happens are shown. In the long run, we can provide suggestions for improving the structure and the mounting design of aluminum frames for the PV module.
