Energy storage isnt the only solution to this problem The excess energy during the day could be used to operate energy intensive machines that dont necessarily need to run all hours of the day, shifting the energy costs of running a modern society into the daytime. For example you could run a desalination plant and produce fresh water, which is especially useful in the hot and arid areas where solar is the most effective. Other things you could run only on excess power include supercomputers for resrarch or some kind of cybersyn digital socialist planning, hydroponics and grow lights for vertical urban farming, electric trains carrying cargo, and all kinds of automated industrial processes. Another idea in the vein of shifting energy use to the daytime is to largely eliminate night shift jobs. Most nightshift jobs are nonessential and only serve to capture more profit for capitalists. Under socialism it is not necessary for every store to be open all night, it is not healthy for workers, and with some variation of a 4/20/69 workweek it isnt necessary for comsumers either, as they have ample days off as well as ample dayight hours on days they are working. Essential services would still operate at night, and some small amount of emergency distribution could remain open for things like medication in case someone needs it while the stores are closed, but for the most part, you dont need groceries at 3am.
