Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaics, and in particular relates to a photovoltaic component installation device. Background Art

[0002] With the development of photovoltaic technology, bifacial modules can generate electricity on both the front and back sides, which can greatly improve the efficiency of sunlight utilization. In addition, their service life is longer than that of traditional single-sided cells, which can greatly reduce the cost of power generation. Therefore, they have received more and more attention and their application range is getting wider and wider. The increase in the power generation of bifacial modules is mainly due to the power generation on the back side of the bifacial modules. However, in the actual application process, in addition to being affected by the intensity of sunlight, the transmittance of bifacial modules will also affect the power generation of bifacial modules.

[0003] The prior art discloses a mounting bracket for improving the power generation performance of a double-sided photovoltaic module, comprising a base, a front column fixedly installed on the left side above the base by bolts, a rear column fixedly installed on the right side above the base by bolts, triangular connectors rotatably installed on the front column and the rear column by bolts, the triangular connector above the front column is fixedly installed below the keel, the triangular connector above the rear column is slidably installed below the keel, two groups of connecting blocks are arranged above the keel, and the connecting blocks are fixedly connected to the photovoltaic panel. This technical solution automatically adjusts the inclination angle of the photovoltaic panel by adjusting the rear column device accordingly according to the information transmitted by the sensor. However, since the double-sided photovoltaic module is placed outdoors for a long time, dust adheres to the double-sided photovoltaic module, a large amount of dust accumulates, and the dust blocks the incidence of sunlight, reduces the light absorption capacity of the photovoltaic module, and reduces the power generation efficiency.
