-Flexible panel configurations place unusual demands on the materials.  Framed panels use extremely durable glass encapsulation((wrapping, basically) but this would not work for flex panels.  One challenge is to come up with encapsulation that is transparent, strong, and durable.

 Originally a clear film called PET was used for the exterior but over time durability issues related to yellowing, increasing opacity, and delamination ("peeling") were revealed, especially in high temperatures or harsh environments.   [[https://en.wikipedia.org/wiki/ETFE|ETFE]] is now commonly preferred for exterior encapsulation layers due to greater UV transparency and durability.  Flex panels that do not mention ETFE are likely encapsulated in PET.
