Solar Panel tests


With our own flasher and our electroluminescent chamber, which we use for quality management and incoming inspection we have the possibility to test your panels on STC-conditions.

How does the electroluminescent chamber works?

A solar cell is a diode that converts sunlight directly into electricity. This process also works in the other direction. A solar cell can operate as a LED (light Emitting Diode). The special NIR-camera can record the radiation.


What can be seen with the electroluminescent chamber?


Ultimately every defect that affects the power production of the solar cell and also entail to a hindrance of the radiation will be emitted in the electroluminescence.


To recognize are p. e.:

- Impurities of the silicium

-Interruptions of the wiper

-Faulty edge isolation of the cells

-With the naked eye not obvious cracks in the silicon wafer
