Description

A solar panel electric micro-water cleaning head

technical field

The invention relates to a solar panel cleaning device, in particular to an electric micro-water cleaning head for a solar panel.

Background technique

At present, the earth can use less and less energy, but solar energy is an inexhaustible energy source. As a clean and pollution-free new energy source, solar energy has attracted extensive attention in recent years, especially in the fields of photovoltaic power generation and photothermal power generation. . However, when photovoltaic panels and heliostats (hereinafter collectively referred to as solar panels) are exposed to the atmosphere, they will accumulate dust and form gray spots, which will reduce the conversion efficiency of solar energy by 20%-40%. Partial coverage of photovoltaic panels by bird droppings and falling objects will cause light spots The thermal effect will damage the photovoltaic panels; when the solar panels are covered by snow, they cannot generate electricity, and it will take longer to wait for the snow to melt naturally.

NASA and Boston University are using the self-cleaning technology developed by Mars missions for photovoltaic panel dust removal, but it has not yet been commercialized due to cost issues. The solar panel dust removal device disclosed in Chinese patents 200710172457.0 and 201110399677.3 is a car wiper structure. The dust removal action span is small and there are dead angles. It is not suitable for the large solar panels with a width of 4 meters and a height of 20 meters in my country, and it is not suitable for the 100 square meters of the Spanish PSA and PS10. Sun Mirror; 201110289151.X discloses a plan that is installed on the slideway on both sides of each solar panel, and the crossbeam equipped with dust and snow removal strips is driven by a motor to remove dust and snow from one end of the solar panel to the other end. The average cost of this scheme is high, and the slideway and the screw mandrel are easy to be rusted in the sun and rain, so it is difficult to implement. At present, the "overflow flushing method", "self-cleaning glass" made of titanium dioxide, "photocatalyst", "new glass anti-corrosion coating" and "manual cleaning" are used at home and abroad to design methods around a single photovoltaic panel or heliostat , the first four methods all require more water, and it is difficult to use them in water-deficient desert areas. "Manual cleaning" has the problems of low efficiency and high cost. According to actual research, a 3MW solar power station is cleaned twice a month, and the annual cleaning labor cost is 1 million yuan. None of the above is the best way to remove dust and snow. For solar power generation, especially large-scale solar power stations, it is very urgent to have a solar panel electric micro-water cleaning head with low cost, high dust and snow removal efficiency, and a small amount of water.
