Solar Photovoltaics with Battery Storage Cheaper than Conventional Power Plants (cleantechnica.com)

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.

Sodium-ion is one of several technologies which might end up being how we do storage; there are a bunch of iron-chemistry flow battery technologies which might be cheaper. It's not at all clear which will be the best choice for stationary storage at this point.

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