Last month, during production supervision, our inspector on the field found 2% of modules, produced in a workshop section, missing silicone sealant between the module frame and glass, due to the improper equipment maintenance. In this case, it was the malfunctions of the sealant machine pressure regulating system. Missing silicone puts the modules at risk of water ingress, potentially leading to delamination and even safety hazard.

Our database indicates that the probability that this type of issue happens is twice as much during night-shifts than during day-shifts. For this reason, we recommend 24/7 Production Supervision.
