One thing Jenny Chase (longtime solar analyst with Bloomberg) likes to point out is that in many places, solar panels are actually cheaper than fencing materials [1]

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.

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

When I bought my solar panels, they showed me their test video of launching balls at them to simulate hail. They said you're toast if it gets to baseball size but below that you should be fine.
