PV panels water drain clips are mainly used to clean sludge and accumulated water above solar panels to ensure the service life of solar panels.
As we all know, the frame of a framed solar panel will be higher than the center of the panel, which will lead to dust and water accumulation in the solar panel during bad weather.
Accumulated water will cause fogging on the surface of the solar panel (a slight rainbow pattern will be seen in the fogging area), which is mold on the lower edge of the PV glass. In this case, the solar panel has caused irreversible damage and its service life has also been affected.
When the accumulated water above the solar panel evaporates, pollution will form in the accumulated water area, blocking the absorption of light, thereby reducing power generation.
According to the algorithm of the inverter, when the maximum power point (MPP) of a solar panel with pollution is lower than that of other panels, the total output power generation will be reduced, resulting in a shading/hot spot effect, thereby reducing the power generation of the entire system. quantity and service life.
At this time, the role of PV panels water drain clips cannot be ignored.
