>Some places are banning putting solar back into the grid because there is no use for the electricity at the time it is put back in.
May be in the northern countries. Cue rolling midday blackouts in CA :) US is a pretty Southern country with a lot of AC running midday - exactly when you have the most solar.
I think the issue here is that midday electricity is the most expensive, ie. the most profitable for the utilities, and solar eats right into it.
>Peak AC consumption is in the afternoon as people get home from work.
not really. The "duck" curve you're referring to is "net" load - ie. actual demand minus solar. The solar smooths/removes the midday peak (which in summer is significantly higher than the evening demand).
