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.
