Solarpunk technology

Sounds strange, but afaik those ~~bifocal~~ bifacial panels have a better side that should be facing where you expect the most sun.

However, I also read that putting them east west is better in some lattitudes and climates at least. Supposedly that allows better collection of low altitude sun in the morning and evening and keeps the panel cooler during mid-day. But I am not sure it is was more efficient overall or just better as a supplement to south facing roof mounted panels. Probably the latter.
