I really like that how it's possible to put bifacial panels vertically along north-south direction to get solar power off peak. It should reduce cost of installation (it's basically multiple rows of fences), snow removal and cleaning. Washing down panels from dust could probably be automated too and if you build them up a bit higher you could have a meadow underneath or even a field of something. Hail should also be probably less of a concern. You need more land of course but it's still awesome.
