Study on the surface stress and the surrounding dust deposition of solar photovoltaic module

Northwest China is rich in solar energy resources and vast land resources, this unique advantage is the reason for the development of solar photovoltaic industry here. However, windy and sandy climate characteristics of northwest are brought hidden trouble to run efficiently and safety for solar photovoltaic modules. This topic through the numerical simulation method to simulate wind load condition of S275 type polycrystalline silicon photovoltaic modules in net wind field, dust particle are added on the basic, to analyze the various factors influencing the settlement of sand and dust around the photovoltaic modules, as well as provides a reference to the design standards for solar photovoltaic system suitable for northwest China climate and landscape environment.
