Insulation measurement with solar modules under wet conditions


Immerse the PV module in a measuring water bath

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.
