But a lot of that is the cost of concentrated solar. On the PV side, batteries are not known for being especially cheap. Lazard puts the wholesale cost of PV plus four hours storage at 8 to 14 cents/kWh, as of 2020: https://www.lazard.com/perspective/levelized-cost-of-energy-levelized-cost-of-storage-and-levelized-cost-of-hydrogen-2020/ https://www.lazard.com/perspective/levelized-cost-of-energy-... And four hours storage is just what you need to shift peak daytime sun to peak evening demand. You need more to get through a windless night. To cover reduced supply on cloudy winter days you need some combination of overcapacity and long-duration storage, which typically involves some kind of turbine.
