In theory, yes, if you can insulate them from ground contact. Using metal post would be an immediate ground. Some wood posts ground more so than others. Figerglass posts won't be strong enough. You will need to find some method of supporting the panels (which are fairly heavy), without grounding them. Something to consider would be to run a separate electric fence around the outside of your pen. This one could be wire strands on fiberglass posts. Personally, I prefer polywire over all metal wire.
