The product is designed to withstand all sorts of extreme weather conditions and safety issues that a module will encounter during its lifetime.
The product is designed to withstand all sorts of extreme weather conditions and safety issues that a module will encounter during its lifetime. Accelerated lifetime testing is a crucial part of the testing sequence of the modules and has been a key focus point in the continuing development of the technology. Selection and further development of a variety of encapsulation systems that can guarantee a lifetime of 20 years is done in close collaboration with different material suppliers, while protecting our own know-how and IP.
The thin film silicon active layers in combination with the very chemical resistant transparent conductive oxide SnO2:F on top, makes the module durable as these layers are not moisture sensitive. If polymeric materials are used it is impossible (or very expensive) to keep moisture out.
