since the panels (with attached ribs and stringers) are shipped from vendors, to would be easy to contact one with the question.. However crown panels weigh less than belly panels which are much lighter than window panels. extrapolating from the weight of an unprocessed piece of skin is also hard because many are chem milled so there is no constant thickness.
The 757 skins are similar but a 5 x 2 meter chunk required a crane to remove from the boxes and hang. (skins were stored hanging for ease and to prevent damage.) part of the problem was size, part was preventing torquing damage, and part was weight. and they didn't have the stringers and clips attached yet.
