We have a need for ceilings. When you account for that the amount of space needed provide ceilings, powering our civilization with solar is a negative number rather than a positive number. Negative, because we can more then power our civilization with existing space through dual purpose structures. An example of this is a solar roof. However, even if you ignore that potential, the amount of space needed is only a few square miles. It's not like it would be the size of a country or even the size of a state. The amount of space is small enough to place in some remote desert and for all intents and purposes to then forget about it.
