Testing crystalline solar modules

PV modules tested. Performance confirmed.

In order to guarantee their function and high yields, PV modules should be checked regularly. Processes such as flash, electroluminescence and thermography tests can be used to determine performance parameters and malfunctions. Possible damage can have different causes.

Test procedures

Flash test

This test shows the performance of the solar panel through high-power LED flashes.

Electroluminescence test

High-resolution electroluminescence images make fractures and microcracks on the solar cells visible.

Thermography test

A thermal imaging camera enables the detection of thermal anomalies in the solar cells in the photovoltaic module.

Errors that can be detected in the PV test centre:

Damage cause

Damage type

Transport damage Installation damage Damage caused by hail Storm damage Lightning / overvoltage damage

Reduced performance / loss of performance Microcracks, brokencell, inactive areas Defective bypass diodes Hotspots and other thermal anomalies Production quality

Important information:

The data sheet and the connector type of the module to be tested must be submitted 5 days before the test date.

In order to get a usable result, the modules must be cleaned.

The modules must be delivered with a lifting platform. With self-delivery, loading and unloading is carried out by the customer.

The test results can be transmitted via dropbox or USB stick. If no USB stick is submitted or brought along, 12.00 €/USB stick will be charged.
