How hot would a composite structure underneath become if one stuck one of these solar panels on your glider?
I'm not a structural engineer but I should think that a tail boom is a rather critical area to be weakening with heat.

The above may have been a jest, but just in case...

Solar panels only give rated power when they are directly oriented
towards a full sun. (And in my experience, usually not even then!) A
solar panel wrapped around a tail boom would only yield a fraction of
its rating. Besides, those particular panels aren't that flexible.

Still, that's a great price for those panels. Thanks for the link.

No need to wrap. The (unimpeachable) specs say dimensions are:
Module Size (MM) 46.5 x 21.3 x 0.1 (2" x 1")!

I read a Schleicher TM about solar panels
that requires a special curing process for
the underlying composite.

2 x K2 batteries do the job for me.
