Mechanical Research Of Solar Photovoltaic Structure

Solar photovoltaic power generation technology is a technology that converts solar energy into electrical energy, at present this technology has been widely used all over the world, so the study about its security and stability is very necessary. Photovoltaic stents generally made of aluminum alloy or stainless steel, but metal material have the disadvantages of high cost, no insulation and so on. The new composite material has the advantages of long service life, high strength, light quality, and good insulation, but due to the advent of the time is not long, the relevant research is less. At present, the design is mainly focused on statics, and the rationality of its dynamics is seldom considered. And the parameters of the solar panels in the layout are mainly determined by the solar light utilization. But for the bad weather area, the structural safety is more important, but few research considered the optimal layout form of solar panels from the perspective of structural safety, resulting in the PV system research is not complete.In this paper, the numerical simulation is carried out for a few kinds of photovoltaic solar powered support structures, To analysis whether the structure meets the strength requirements when using the composite support. The corresponding modal information is calculated and the improved scheme is proposed. The flow field around the solar panels and the characteristics of the solar panels are analyzed. And finally tried to synthesize the typical wind load, Dynamic analysis of the typical wind load on the structure is carried out. This paper has positive significance to the improvement of the photovoltaic solar energy board design and arrangement.The work of this paper lies in the design optimization of composite solar photovoltaic bracket and solar panels optimum arrangement, explore the new method for studying the structure of wind load dynamics, shorten the product development cycle.
