Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a track-type cleaning and dust removal device for photovoltaic panels, and in particular to a dust removal device for photovoltaic panels with spraying and brushing functions. Background Art

[0002] During the use of photovoltaic power stations, the surface of photovoltaic panels will gradually be covered by dust over time. Dust forms a thin film on the surface of photovoltaic panels, affecting the efficiency of photovoltaic power generation. Dust will cover the tiny concave and convex structures on the surface of photovoltaic panels, reducing the power generation efficiency of solar panels. Dust absorbs part of the solar energy, affecting the timely and full conversion of solar energy into electrical energy, reducing the efficiency of solar energy utilization. At the same time, dust will reduce the working efficiency of the inverter, affect the heat dissipation of the radiator, and increase the surface temperature of the solar panel, which will reduce the power generation efficiency of the solar panel.

[0003] Studies have shown that under the same conditions, the output power of clean solar panel components is at least 5% higher than that of dusty components, and the higher the dust accumulation, the greater the decline in component output performance. It is important to regularly remove dust from photovoltaic panels to ensure the normal power generation operation of photovoltaic panels.

[0004] Traditional photovoltaic panel dust removal uses manual dust removal, which has low dust removal efficiency and poor dust removal effect. After the dust removal process of some photovoltaic panels has been improved, such as CN 206878765 U, a spray pipe is used to wash the photovoltaic panel to complete the dust removal, but it is difficult to clean the more stubborn dust stains, and the cleaning and dust removal effect is not ideal.
