Solar panel micro cracks, or more precisely micro cracks in solar cells pose a frequent and complicated challenge for manufacturers of photovoltaic (PV) modules.
There are different quality testing methods to identify micro cracks of which electroluminescence (EL)or electroluminescence crack detection (ELCD) testing is one of the most applied method.
EL testing can detect hidden defectsthat were before untraceable by other testing methods, such as infrared (IR) imaging with thermal cameras, V-A characteristic and flash testing.
It is an image analysis and measurement process allowing to peer directly into the cells of a pv module and locate potential inherent defects.
Optimally, EL testing is performed once before lamination so that the defect solar cells can be replaced and then again after (careful) lamination.
Visually, micro-cracks may appear in form of so called snail trails on the cell structure. However, snail trails – as a long-term impact sign – can also be the result of chemical process causing the surface of the cell to change and/ or hot spots.
Therefore, visual checking of PV modules aloneis not an effective method to identify micro-cracks and should not replace a thorough EL test.
