I seem to remember reading advice of the form, "fuse any wire that goes to the battery + post, as close to the post as possible." So assuming the + side of your bus goes directly to battery +, that's what I would fuse.
Probably I read it in Don Casey's "Sailboat Electrics Simplified."
p.s. that said if you have, say, a 9A fuse on the bus's + wire and each panel puts out 3A, then an overload in any of the panel wires won't necessary blow the fuse. Of course, it's not clear to me, short of, well, a short, how a panel wire might overload.
