Solar energy has the advantages of abundant resources, longevity, wide distribution, safety, cleanliness and reliable technology. Since solar energy can be converted into many other forms of energy, its application range is very wide. To obtain electricity from solar energy, it needs to be achieved through photoelectric conversion of solar cells.

[0003] Most existing photovoltaic systems first set up the support system, and then install the photovoltaic panel components from the top of the support system. In order to ensure the waterproof integrity of the entire photovoltaic system, a waterproof cover plate of a cleaning rod is pressed against the surface of the adjacent photovoltaic panel components, and the waterproof cover plate is connected to the support below, so that the photovoltaic panel components are fixed and the waterproof cover plate of the cleaning rod and the photovoltaic panel components form a complete waterproof surface. However, this will form a narrow closed space between the waterproof cover plate, the adjacent photovoltaic panel components and the support. The water entering the closed space is likely to form a "steamer effect", thereby accelerating the corrosion of the profile. Summary of the invention
