"Dave] is using bifacial solar panels– panels that have cells on both sides. In his preferred orientation, one side faces South, while the other faces North. [Dave] is in the Northern Hemisphere, so those of you Down Under would have to do the opposite, pointing one face North and the other South"

um, yes, do the opposite.

It’s a good joke, but it’s also not a joke.

There’s different kinds of bifacial panels out there. Many of them actually have a front and a back side, and the front is a little bit more efficient than the back.
