[0002] Many distributed photovoltaic power stations are built on colored steel tiles on the roofs of factories. However, due to the small inclination angle of the colored steel tiles, the photovoltaic group is also called photovoltaic panels, and the laying angle is also small. Dust in the air will fall on the photovoltaic components, and rain will be accompanied by dust. The photovoltaic panels are blocked by aluminum alloy frames around them. After the rain evaporates, a layer of gray belts of varying thickness and width is formed. This gray belt forms a partial obstruction of the solar cells, causing the bypass diode inside the photovoltaic panel to be turned on, resulting in a barrel effect, which will lead to a reduction in power generation of up to 75%. The partially obscured photovoltaic cells will produce different degrees of hot spot effects, which will damage the photovoltaic panels and bring safety hazards. Utility Model Content
