everything about energy production
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.
I think it doesn't matter too much. Suboptimal energy storage is still much better than none.
