How they hold up to kid’s soccer balls tho?

Unfortunately, she doesn't say what kind of fence she's talking about. The kind of fancy privacy fence people put up between yards, maybe; but I'd be impressed if they're cheaper than livestock fence, which is the context some people are talking about in this thread. A typical cattle fence (woven wire, steel posts, barbed wire on top) will cost about $2500 per quarter-mile right now for the materials.

I'm not sure what a quarter-mile of solar panels four feet high would cost, or whether they'd survive the occasional cow rubbing on them. Neat idea, though.
