How much moisture can your module withstand?
Insulation measurement with solar modules under wet conditions
Immerse the PV module in a measuring water bath
More information?
Do you have any questions about the measurement procedure or individual requirements?
This is how we proceed:
We immerse the PV module from the glass side until half of the frame height is in the water bath. We also irrigate the rear side, including the junction box, with water.
This is how
the insulation measurement works:
The connecting lines are short-circuited at a voltage source and supplied with an corresponding current. A sensor now measures any current that could potentially leak from the PV module.
The result
In this test, we measure any leakage current flowing through a path that is not intended to conduct current to the PC module. If there is a leakage current at a component of the PV module, an electric shock would occur when touching it.
