Thermal energy storage is pretty great, as phase-change energy storage is very consistent with its energy output over time, unlike chemical batteries. You also get your pick from a wide range of ma…
There are industrial-scale versions of this already. Not as a solution for excess solar power storage, but to take advantage of off-peak electricity costs.
Generally, off-peak prices are about demand rather than supply. They are lowest at night due to the lowest demand being at night, while supply (from e.g. nuclear) remains constant.

Which is not too far off, I would say. Not to say the same, since prices probably follow peak production of solar energy. 🤔
