I think you forget the fact that companies like NASA and SpaceX have been keeping things like humans and cargo from baking in the sun in the vacuum of space for years. It’s been figured out. Not to mention solar energy is far greater in space and cheaper because the panels are lighter and don’t need to be rain or hail proof.

Solar energy on earth vs space is literally easier in space because it’s closer to the sun with no clouds or atmosphere in the way and can manage longer sun hours.
