@kravietz So there are a few days a year it might get too cold and they freeze up, or certain arctic regions they dont work... ok... your point? They are still fairly effective means of generating green energy, but they arent the whole of the solution.
@freemo
Surface power density "useless"? Come one... If you need to occupy 250x larger area to obtain the same amount of energy I think it's very relevant, and practically makes it useless in high-density areas.
Capacity factor "not remotely true"? Come on... PV peaks 13% in UK, wind 40% for off-shore.
So you not only occupy larger space for the actual generation, but then need to double that for low CF, and then tripe for storage.
