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.
