As an important part of solar system, solar mounting bracket carries the main body of power generation of solar station. The choice of pv panel bracket directly affects the operational safety, damage rate and construction investment of photovoltaic modules. Choosing a suitable solar mounting bracket can not only reduce the project cost, but also reduce the subsequent maintenance cost.
1. PV brackets types---according to material classification
According to the different materials used for solar panel racks, they can be divided into aluminum alloy mounting racks, steel structure and non-metallic supports. Among them, non-metallic supports are less used, while aluminum alloy supports and steel supports have their own characteristics.
2. Classification according to installation mounting type
The pv array does not rotate with the change of the sun's incident angle, and receives solar radiation in a fixed manner. According to the setting of the inclination angle, it can be divided into: the best inclination angle fixed type solar mounting racks and adjustable solar mounting solution and solar tracking systems.
Optimum tilt angle fixed photovoltaic bracket
The fixed type is roughly divided into inclined roof bracket, flat roof bracket and ground bracket according to different installation sites.
A. Fixed inclined roof
Considering that the load-bearing capacity of sloping roofs is generally poor, most of the components on sloping roofs are directly installed flat, and the azimuth and inclination angles of the components are generally consistent with the roof. According to the difference of inclined roof, it can be divided into tile roof installation system and light steel roof installation system.
Tile roof mounting systems
It is composed with rails,clamps and tile roof hooks for project.
Metal roof mounting systems
It is composed with rails,clamps and L brackets for universal trapezoid tin roof,and standing seam roof clamps for clip-lock roof types.

Fixed mounting rack with adjustable tilt angles in a certain level
The fixed inclination adjustable type means that the inclination angle of the fixed bracket is regularly adjusted at the turning point of the sun's incident angle to increase the absorption of direct sunlight and increase the power generation capacity at a slight increase in cost.
Solar Tracking Systems
The tracking type photovoltaic bracket uses electromechanical or hydraulic devices to make the photovoltaic array move with the change of the sun's incident angle, so that the sunlight is as direct as possible to the module panel, and the power generation capacity of the photovoltaic array is improved. According to the number of tracking axes, it can be divided into: single-axis tracking system and dual-axis tracking system.
