The present invention relates to a washing apparatus for a solar panel, and more particularly, to wash the surface of the solar panel can be uniform washing for a large area, washing for the solar panel that can reduce the amount of washing water used Relates to a device.
In general, a method of using solar energy is largely divided into a method using solar heat and a method using solar light. The method of using solar heat is a method of heating and generating electricity by using water heated by the sun, and a method of using sunlight is a method of generating electricity by using sunlight, It is called solar power generation.
In the above-described method, the photovoltaic effect is generated when the solar cell is irradiated with solar light on a pn junction photovoltaic panel with n-type doping on a silicon crystal. Generate electricity using
To this end, a solar cell for condensing sunlight, a photovoltaic module which is an assembly of solar cells, and a solar array in which the solar cells are constantly arranged are required.
For example, when light is incident on the solar module from the outside, electrons in the conduction band of the p-type semiconductor are excited to the valence band by the incident light energy, and the excited electrons are p One electron-hole pair (EHP) is formed inside the semiconductor, and the electrons of the electron-hole pairs generated are transferred to the n-type semiconductor by an electric field existing between pn junctions. To supply current to the outside.
Unlike existing energy sources such as fossil raw materials, sunlight is a clean energy source that does not have the danger of global warming, such as greenhouse gas emissions, noise, environmental destruction, etc., and there is no fear of depletion. In addition, unlike other wind and sea power, photovoltaic power generation facilities are widely used due to the advantages of free installation and low maintenance cost.
However, the solar module has a disadvantage in that various foreign matters can be easily accumulated due to meteorological phenomenon such as yellow sand and bad weather on the solar panel. That is, the photovoltaic module may have a low light absorption rate when various foreign matters are accumulated on the surface, thereby reducing power generation efficiency.
In addition, when rain or snow falls on the solar panel in winter, power generation efficiency may decrease.
As such, the solar modules are often washed to prevent deterioration of power generation efficiency due to various foreign matters and snow accumulated on the surface of the solar modules.
Conventional photovoltaic module cleaning method, but manual washing using manpower, enormous time and labor costs for the washing operation, too much washing water is required, there was a problem of occurrence of safety accidents. In addition, there is a problem that the scratch generated on the surface of the solar panel by the cleaning tool during the cleaning, the power generation efficiency is lowered.

Republic of Korea Patent Registration No. 10-1044713 (Registration Date: June 21, 2011) is a form of spraying the cleaning agent by installing a cooling water injection means on one side of the solar module, away from the cooling water injection means when cleaning the solar module Not only is it difficult to remove contaminants located in remote areas, but the cleaning efficiency is inferior due to the structure that a large amount of washing water is used to remove contaminants at a long distance.
Republic of Korea Patent Registration No. 10-1193122 (Registration Date: October 15, 2012) is installed on both sides of the photovoltaic plate and installed the horizontal bar moving along the guide rail to cross the washing water supplied from the washing water supply Uniform cleaning is possible for the large area of the solar panel by spraying it on the solar panel through the cleaning unit installed in the bar, but the horizontal bar is always placed on the solar panel, thereby forming a shadow on a part of the solar panels connected in series. There is a way that the efficiency can be drastically lowered. In order to prevent this, when the horizontal bar is disposed outside of the solar panel, the overall structure of the cleaning device and the solar power generation facility may be complicated, and accordingly, installation costs may increase.
Accordingly, while cleaning the surface of the solar panel is possible to wash uniformly over a large area while reducing the amount of washing water used, the study on the solar panel cleaning device that can prevent the formation of shadows on the solar panel after washing Development is required.
