Simulation Wind Load and Sand-dust Deposition Surround the Solar Photovoltaic Modules

Abstract

Solar PV modules toward the development of lightweight against the wind performance made a high demand. In order to ensure the long-term efficient and stable operation of the solar power station in the desert dust environment, it is necessary to analyze the movement state of the dust in the sandstorm gas-solid two-phase flow in the desert environment. In this paper, the wind load of S275 polycrystalline silicon PV modules in the net wind field is simulated by numerical simulation method. Based on this, the dust particles are added and the factors influencing the settlement of dust around the PV modules are analyzed. To further analyzing the dust on the erosion of PV modules to lay the foundation.
