If you're planning on MOVING all the hog panels weekly...I would ask why.
I wouldn't put any number of pigs on less than 1/8 of an acre. They like to explore, they're not ruminants that just chew cud all day. Limit their space too much and they'll try to get out. That said, you can keep quite in a 1/4 acre at a time if you move them frequently.
I'm trying to figure out why you would move hog panels weekly instead of just using electric. You can run a charger off a 12 volt battery. Get 2 deep cycle batteries and change the battery every day to be safe, while one is on the fence the other is charging. For pig electric you just need 2 polywires. We use fiberglass posts but heck, you could cut your own from wood and a bag of plastic clips for the polywire is like $10, that's all you need.
Yes the charger is going to cost you a few hundred dollars, but I would think you could resell it if you don't want to keep it and it's going to be cheaper than hog paneling 1/8 of an acre.
Use the 16x32 hog panel pen to train your piglets to the fence. Put the polywire right next to the panel so they bump into the wire, get a shock, and then bounce off the fence. If they're happy where they are (food, water, stuff to root around in) they'll learn fast to respect the fence.
