PV Modules Cleaning Clips For Water Drain

When solar panels are installed on rooftops at a slight angle, there is a tendency for module frames to collect rainwater. As the water evaporates, dust residue is left behind.
It is made of hydrophilic plastic. Why not use metal materials to make drain clips? Because metal materials have poor hydrophilicity, they will be clogged up with dirt if used for a long time.
How to install drainage clips? First, make the whole surface clean, and clasped the water clip to the bottom edge of the module, if rains again, there will be no mud zone.
Where to install the clip? It was installed at the position where the rainwater accumulated most. Corresponding to the shapes of dust residue, it needs to be installed in different positions, usually two clips are enough.
