Looking into the future
Defect catalogue: Electroluminescence is without a doubt in vogue. But there is still some debate over what the method actually reveals and how the images should be interpreted. We present typical module defects revealed by EL imaging.
Electroluminescence is an image-producing process that enables cost-efficient, non-destructive examination of modules to determine the quality of manufacturing and handling. It is also extraordinarily well suited to troubleshooting photovoltaic modules in the field. But you have to know what you’re doing. Just how much the pictures can reveal is highly dependent on image quality. Resolution …
