Is the damaged PV module still usable? No,it can't use it anymore.

In response to this question, our team of engineers took a damaged module from the industrial solar power system factory for experiment: a photovoltaic module have many densely cracked. The engineer connected the circuit to this solar panel, and the damaged photovoltaic module output 9 a current and the voltage is as high as 650V, which is fatal to human body, and there will be a generation between positive and negative wires An arc like a flame.

Even if only the surface tempered glass was damaged, the 12V solar cell voltage jumped to 300V under the action of water flow. Therefore, once the solar panel is damaged, we should pay attention to it, let alone clean it with water.

If the solar panels are damaged, what do we need to pay attention to?

An engineer from our industrial solar power system factory said:

1.)Don't touch the damaged solar panel with bare hands. If you need to touch it, please wear dry wire gloves or rubber gloves and other insulating gloves.

2.)When multiple solar panels are connected by cables, the cables should be pulled out or cut off. If possible, cover the panel with a blue tarpaulin or cardboard, or keep the front side down to avoid sunlight.

3.)If possible, wrap the exposed copper wire in the cable section with plastic tape.

4.)When the solar panels are transported to the abandoned place, it's best to break the glass with a hammer.
