However, if there is foreign matter such as snow or leaves on the surface of the solar cell, a problem occurs in generating electricity by using sunlight. If foreign matter such as snow covers the entire solar cell, the solar cell does not receive sunlight and cannot generate power. In addition, even when a foreign material such as a leaf covers only a part of the solar cell, a problem occurs in the entire solar cell. When some cells do not receive sunlight in the solar cell module composed of a plurality of cells, the current produced in the normal cell is reversed to the cells that do not receive sunlight, causing an overall decrease in efficiency. Even, excessive current flows back to the cell that does not receive sunlight, and the temperature of the cell that does not receive sunlight increases excessively, and the cell is destroyed due to the high temperature, that is, a hot spot phenomenon occurs.

To prevent this, there is a method of adding a bypass diode, but removing the foreign matter on the surface of the solar cell is the most fundamental countermeasure. Moreover, due to the nature of the stone installed outdoors, it is not easy to continuously monitor the surface of the solar cell and remove foreign substances.
