The panels can help reduce total grid usage during the day to help supply power to businesses where people are during the day. A home AC shouldn't be running much during the day if no one is home so that helps with reducing the load. Once it gets dark, the load shifts back to homes where people are charging their cars and running the AC more heavily. I imagine the heaviest load times would be in the evening when solar panels aren't providing much power, the AC is starting to run to cool the house down, and people are starting to plug in their cars. Large power storage systems should be in place to help smooth out these increases in demand.

Daytime load is basically not a problem in California or elsewhere in the US. In fact, load minus solar is already lower at noon than at midnight. [0] This is referred to as the "duck curve". As such, load shifting should be the opposite of what you suggest - we should be doing things like cooling houses to 60 degrees during the day so that the AC doesn't have to be run in the evening, encouraging people to charge cars during the day and other things like that. 0: https://en.wikipedia.org/wiki/Duck_curve https://en.wikipedia.org/wiki/Duck_curve

  > we should be doing things like cooling houses to 60 degrees during the day so that the AC doesn't have to be run in the evening I'm dubious that this is a good idea. Cooling your house to 60 degrees on a hot day burns a huge amount of power needlessly. The amount of energy loss in a typical house is so big, this is a massive waste. Your assumption seems to be that you can bank power, using air temperature to try and story energy when it's inside a big leaky box is futile. Keeping the indoor temp at 78 all day and cooling it to 72 around an hour before you get home is going to be far more efficient. If you want to burn power during the day, run your dishwasher and run a timed dryer load. If you want to bank it, buy a battery.
