Problems solved by technology

With the rapid development of science and technology and industrial economy in recent years, the traditional solar photovoltaic support has been subjected to acid rain erosion for a long time due to poor acid resistance, and is prone to vibration under the influence of natural wind, which will deform the solar panel on the support and lead to the use of solar panels. The life span is shortened, and it needs to be solved urgently
