TECHNICAL FIELD
[0001] The present application relates to the technical field of mountain photovoltaic module cleaning, in particular to a snow and dust cleaning device for mountain photovoltaic module. BACKGROUND
[0002] In rainy and snowy weather, the mountain photovoltaic module is covered with snow, which reduces the power generation or even stops the power generation. After the rainy and snowy weather, the snow needs to be removed to make the module generate power as soon as possible. The influence of rain and snow on the photovoltaic panel mainly includes short-term negative shielding and long-term cleaning benefits. The core is the temporary fluctuation of power generation. The snow cover or water film formed by rainwater directly shields the sunlight, which reduces the solar energy absorbed by the photovoltaic panel and significantly reduces the power generation. In extreme cases (such as thick snow accumulation), the power generation may be temporarily stopped. The long-term impact: Rain and snow can naturally wash away the dust, bird droppings and other dirt on the surface of the photovoltaic panel, which is equivalent to free cleaning, restores the light transmittance of the panel, and the power generation after the rain and snow is usually more efficient than before. However, it takes a certain amount of time for the rain and snow to naturally melt, so it is necessary to design an intelligent snow and dust cleaning device to effectively improve the power generation efficiency of the power station.
