Abstract
Firstly, this study establishes the simulation model of double-glass photovoltaic module based on the finite element method and verifies the simulation results experimentally. Then the length, width, height and thickness of the photovoltaic module are selected as influencing factors, and multiple orthogonal design is carried out taking the minimum module cost and optimal strength as the objective. Finally, the optimal size of the photovoltaic module is obtained by the Pareto method. The results show that the maximum error between the experimental and simulated values of the component center deformation is only 7.33%, which Verifies the accuracy of the simulation results. The maximum stress increases with the increase of length, increases first and then decreases with the increase of width, decreases with the increase of height, and has no obvious change with the increase of thickness. The price decreases with the increase of length, slightly decreases with the increase of width, greatly increases with the increase of height, and increases with the increase of thickness. When the module length, width, height, and thickness are 1200 mm, 787.5 mm, 37.5 mm, and 1.5 mm, respectively, the stress requirement is satisfied and the cost is the lowest. The cost of optimized structure is reduced by 8.41% compared with the initial structure.
