Yeah I think it really only works well in the central latitudes. The American South, the tropics and equatorial regions, Southern Europe, etc. that get a lot of high-angle sunlight year-round.

Otherwise you need to deal with long distance power transmission across many political jurisdictions, or local generation for night or other low-solar times. To my mind, nuclear base load with solar and batteries used for things like charging cars or demand-shifting probably makes more sense. It's really a shame that we mostly withdrew from building nuclear plants for the past three or four decades; instead we have reached the point where we have to re-learn how or recreate the tooling needed to build them and they are still too damn expensive.
