Sandstorm preventing and dust eliminating single-axis photovoltaic tracking power generation system structure

Abstract

The invention discloses a sandstorm preventing and dust eliminating single-axis photovoltaic tracking power generation system structure. A first fixed bracket and a second fixed bracket are respectively connected with two ends of a rotating shaft, the back of a photovoltaic assembly is fixed on the rotating shaft, and the photovoltaic assembly can carry out 0 to 360-degree bidirectional rotation together with the rotating shaft under drive of a motor; the motor, a control module, a first pressure sensor and a second pressure sensor are arranged on the second fixed bracket; the angle between the first pressure sensor and the rotating shaft is alpha degrees, and the angle between the second pressure sensor and the rotating shaft is (180-alpha) degrees; and a weather observation instrument is arranged on one side of the first fixed bracket and used for monitoring signals of wind direction, wind speed, rainfall and light intensity and transmitting the monitored signals to the control module. Through the structure, the surface cleanliness of the assembly is improved, the hot spot effect is reduced, the ray incidence rate of the surface of the assembly is kept, the photoelectric conversion efficiency is improved, dust on the surface of the photovoltaic assembly can be effectively cleaned, and the manpower cost is reduced.

Description

technical field [0001] The invention relates to a structure of a single-axis photovoltaic tracking power generation system with wind and sand protection and dust elimination. Background technique [0002] Photovoltaic modules are usually installed outdoors to receive sunlight and generate electricity. During use, the surface of the photovoltaic module is easy to be covered with dust, resulting in a hot spot effect, which will directly reduce the photoelectric conversion efficiency and thus affect the operating efficiency of the entire system. Therefore, it is necessary to maintain the cleanliness of the surface of the photovoltaic module. For photovoltaic modules installed in deserts and other areas with strong wind and sand, sand is more likely to accumulate on the surface of photovoltaic modules, and sand particles will also damage the surface of photovoltaic modules, which will seriously affect the photoelectric conversion efficiency. Therefore, it is necessary to minimiz...

Problems solved by technology

During use, the surface of the photovoltaic module is easy to be covered with dust, resulting in a hot spot effect, which will directly reduce the photoelectric conversion efficiency and thus affect the operating efficiency of the entire system. Therefore, it is necessary to keep the surface of the photovoltaic module clean.

For photovoltaic modules installed in deserts and other areas with strong wind and sand, sand is more likely to accumulate on the surface of photovoltaic modules, and sand particles will also damage the surface of photovoltaic modules, which will seriously affect the photoelectric conversion efficiency. Therefore, it is necessary to minimize the adverse effects of wind and sand on photovoltaic modules. Impresses and improves the cleanliness of photovoltaic module surfaces

[0003] At present, the cleaning method of large-scale photovoltaic modules is mainly manual scrubbing, which not only has low work efficiency, but also increases the cost of operation and maintenance. Some of them are cleaned directly with water, which is not efficient, and for photovoltaic system, adding to the problem of finding and storing water
