It should be judged and selected from the side. For example, the following aspects are erected solar mounting structure, tracking moving parts, solar mounting component materials, component processing technology, quality assurance time, and effective use time. For photovoltaic solar brackets, the product descriptions between networks always include parameters, installed capacity, control methods, tracking (accuracy, elevation, azimuth), safe operation capabilities, drive (type, electric power), protection capabilities, and work Environment, area, finishing weight, etc. It is not that the parameters are not important, but that if you cannot understand many parameters, you should focus on understanding the detailed situation from the side, and then compare the parameters after a preliminary understanding. Fabrics and treatments with different parameters will also vary a lot. This is one of the reasons why the brand's products are still high in price although their parameters are not high in comparison. From the perspective of non-professional users, the choice of photovoltaic stents is mainly considered in practical fields such as materials. Regarding the parameters, it can be said that as long as the requirements that need to be met are put forward, the manufacturers will generally meet or explain them.
