The installation system thereby effectively reduces the load of the roof installation of the photovoltaic system, and can adjust the angle according to the requirements of different seasons to increase the power generation.
【Background technique】
[0002] The population density in the eastern part of China is large, and the degree of industrial modernization is high. The demand for electric energy is much larger than that in the western region. The state encourages the development of distributed photovoltaic power plants on the roof. In the eastern region, there are a large number of industrial plant roofs that can be used as carriers for distributed solar photovoltaic power plants to reduce the occupation of land resources. There are many non-superior roofs in the concrete roof. The bearing capacity of the roof is 0.5KN/M2. The fixing method of the traditional cement load block will greatly increase the burden of the original roof constant load and cause safety hazards. Moreover, the lighting resources in the eastern region are inferior, generally belonging to the third and fourth types of light areas. The amount of power generation is directly related to the revenue of photovoltaic power plants. Most of the existing roofing power stations are solar panels installed at fixed angles. The quantity has a direct relationship with the installation angle. The incident angle of solar energy varies in different seasons. The PV modules are installed at a fixed inclination. The angle cannot be adjusted with the season, and the power generation cannot be increased in an appropriate amount. The traditional electric tracking bracket has high input cost, difficult maintenance in the later stage, high failure rate and poor economy.
