Whether the photovoltaic power station can capture more sunlight is the top priority of photovoltaic power generation. The special structure of photovoltaic support is specially designed to help support and rotate photovoltaic modules to achieve the best irradiation angle.
In order to achieve the best power generation efficiency of the photovoltaic power station, the photovoltaic support should be combined with the topography, climate and solar resource conditions of the project site, and the photovoltaic modules should be fixed in a certain orientation, arrangement and spacing.

For photovoltaic power stations with fixed brackets, at the beginning of the design, the modules will be fixed at a specific angle in combination with the local geographical environment, climate and other conditions to ensure that they can receive the maximum solar radiation. In the case of adjustable brackets, the component orientation will need to be manually adjusted each year depending on the season and light conditions. The fixed bracket has low price, good stability and low initial investment cost, but the utilization rate of solar energy is low.

· For photovoltaic systems using tracking brackets, the orientation of the components is adjusted according to the light conditions, which can reduce the angle between the components and the direct sunlight, obtain more solar radiation, and effectively improve the power generation efficiency. The actual power generation data show that the use of flat single-axis tracking brackets, inclined single-axis tracking brackets, and dual-axis tracking brackets can effectively increase the power generation of the power station. It can generate 15%~25% more power than the fixed bracket. In the long run, it will help the power station owner to obtain the greatest economic benefits and reduce the cost of electricity.
