Unlike existing energy sources such as fossil fuels, solar power generation is a clean energy source with no risk of greenhouse gas emissions, noise, or environmental destruction that causes global warming. There is no fear of depletion, and unlike other wind or seawater power, solar power generation is a clean energy source. It has the advantage of being free and low maintenance costs.

However, the surface of solar panels that are installed outdoors and exposed to the external environment and used for a long period of time are easily contaminated by various foreign substances such as dust, yellow dust, dust, snow, salt, and bird excrement. Since problems occur that reduce the power generation efficiency of the solar panel, periodic cleaning of the solar panel surface is necessary to maintain the power generation efficiency of the solar panel.

Meanwhile, when the driving unit 30 is driven, the static electricity generation bar 10 moves back and forth from one end of the solar panel 1 to the other end of the solar panel 1 as one cycle, and when one cycle is completed, the static electricity generation bar ( The foreign matter 2 adsorbed in 10) can be removed from the static electricity generating bar 10.

As shown in FIGS. 4 and 5, when the foreign matter 2 of the solar panel 1 is removed, the static electricity generating bar 10 is used to remove the foreign matter 2 from the solar panel 1. After completing one cycle of reciprocating movement from one end side to the other end side, the foreign matter 2 attached to the outer surface of the solar panel 1 is adsorbed and maintained on the static electricity generation bar 10, and then the static electricity generation bar 10 is maintained in a state of adsorbing When the bar 10 moves to the one end side, the power supply unit 20 cuts off the power supplied to the bar 10 to remove static electricity, thereby reducing the electrostatic force formed in the bar 10.
