Hog panels are made of pretty heavy gauge wire. As long as the supports holding them upright are strong enough to support the weight you should be fine. The support ability of the ground is really the deciding factor.
T posts are one way to support the hog fence. You just need to find t posts long enough to make a good bite into the ground.

I've used hog wire to make locking cages for tool storage and I can tell you it's pretty strong but it is a little floppy. If you have hanging fruit densely packed, high winds may pose a problem.
