Is this an actual boundary fence or just some free-standing vertical solar panels? Is there any reason they should be vertical instead of facing the sun? Where I live, it would be more efficient for them to be at a roughly 40 degree angle (I think)

You get a different generation curve (more energy in mornings and evenings) with vertical bi-facial panels. Though this person is in a woody area which might not see that benefit.
That’s specifically for e/w bifacials, you don’t get that with N/S panels.

North/south bifacial shifts the generation seasonally, trading much less in summer for a bit more in winter when the sun is low.
Indeed.

Takes up a smaller footprint of land, and PV panels themselves are now so cheap and last so long that it borderline makes sense as a fencing material even if you don't connect them to an inverter and power and anything with them.
