For air conditioning, one solution is to make ice when electricity is cheap, and then use that for cooling. Here's an example unit: https://www.ice-energy.com/ https://www.ice-energy.com/ This concept dates back to the 1950s. The usual application then was to cool during the day using electricity delivered at night; now it's flipped, and you can make ice during the solar peak for cooling the rest of the day.
