I think that's correct for thin film panels. But it appears that monocrystalline panels can be manufactured with some flexibility. Hence my usage of the term "semi-flexible". Sunpower, for example, claims to produce high efficiency semi-flexible monocrystalline panels that would flex sufficiently for use on a bimini top, for example.
It further appears that my statement "high efficiency panels are typically semi-flexible without the frame" is inaccurate- they are typically not reasonably described as semi-flexible, even without the frame and coating.
- walrus01 6y agoReal high efficiency monocrystalline si cells are not flexible in any way, for example the typical 156mm cell that makes up a 315-400W rated 60 or 72 cell panel. In fact they're quite brittle and fragile when not encapsulated on a backing sheet and under protective glass. Monocrystalline by definition is not flexible, you're referring to thin films (cadmium telluride or amorphous silicon or other)
- mkingston 6y agoThanks for the reply. Is there any middle ground? Is Sunpower's claim of 22-25% efficient monocrystalline semi-flexible panels not to be believed? Have I been fooled by the marketing? Are these thin film panels? Nothing I can find online suggests this is a dubious claim, but it's possible I'm simply failing to find correct information.
