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
