Fixed installation of solar photovoltaic modules on flat roof

Solar photovoltaic modules are installed on flat roofs. Currently, the most popular bracket styles on the market are triangular support, front and rear legs, and bottom basin support. These installation methods are through through-fixing or applying with the roof. Re-achieve the wind resistance of the overall stent. Almost all flat roof brackets are changed in different ways in these three styles. For example, the triangular support type of three-section support can be combined by different sections, and the triangle bracket can be designed to be telescopic or adjustable. Style, and the guide rail above the triangular support also has various cross sections.


 If the guide rail is side slotted, the assembly can be slid into the bracket by the side slot, or the guide rail can be designed to be placed under the photovoltaic component. One-quarter and three-quarters of the frame are held in place by clamps or other fasteners. The triangular support type is relatively stable in structure, and it is convenient to control the mechanical properties of the overall support by adjusting the distance of the triangular support, and thus is most common in the market. However, since the assembly is fixed to the support by the guide rail, the effect of the guide rail on the triangular support is concentrated, so the mechanical performance of the triangular support is required to be high, but due to the structural limitation of the triangular support itself, the sectional design cannot be complicated. The mechanical properties can only be improved by increasing the size, and the increase in size has a great influence on the cost of the stent. The front and rear legs are also more common. 


The front and rear legs are fixed to the ground through specially designed connectors or floor rails, and the rails are fixed at the top of the front and rear legs or directly with the non-standard solar frame. However, since the four legs are independent of each other, during the installation process, whether the track is mounted on the front and rear legs or the frame of the component and the front and rear legs are fixed, there is a huge workload. In addition, due to the excessive degree of freedom of the four legs, it is difficult to install and fix the components, especially the adjustment of the level of the solar module in the later period takes a long time.
