I’ll note that aggregate system cost still benefits significantly from including wind and other non-solar sources of energy; having a mix of different intermittent sources (and some firm generation such as geothermal) means less storage is needed.

Also you have to consider conventional hydro. The reservoirs have considerable storage capacity, which is obviously limited by a lot of factors.
