Mini-module classification

The benchtop system PIDcon enables the routine quality control of mini modules as a fast and low cost test of the PID susceptibility, where no climate chamber or other expansive tools are needed.

Mini-module classification

Potential induced degradation (PID) is a serious reliability problem in PV power plants. Hence it is important to investigate its products on their PID susceptibility. The aim of the PIDcon is to enable the producers to test their product earlier in the production chain e.g. on mini-modules. Note that the PID that is considered here is the shunting of the solar cells due to high voltage stress induced leakage currents (PID-s).

The mini modules are contacted via 2 contact points and via a contacting check a good contacting is ensured.

The software PIDStudio enables the user to set a pass and fail criterion and it also suggests one according to the IEC standard and experience of the scientist from Fraunhofer CSP.
