[0002] Solar photovoltaic glass consists of low-iron glass, solar cells, film, back glass, and special metal conductors. The solar cells are sealed between a sheet of low-iron glass and a back glass via film. It is a cutting-edge high-tech architectural glass product. The low-iron glass covering the solar cells ensures greater light transmittance and generates more electricity. Tempered low-iron glass offers increased strength, allowing it to withstand greater wind pressure and significant temperature fluctuations between day and night.

[0003] In the existing technology, photovoltaic glass is generally first transported into the starting area of ​​the cleaning equipment, which is usually equipped with an automatic loading device, such as a robotic arm or a roller conveyor belt, which can smoothly transfer the photovoltaic glass from the production line to the inside of the cleaning equipment, and then equipped with multiple sets of brush rollers for cleaning.

However, due to the separation design between the roller brushes in the flushing channel during operation, when the roller brush contacts the glass, the flushing channel is difficult to accurately and efficiently spray water on the glass surface, which easily causes scratches on the surface and residues after cleaning.
