> The sun is going to be the strongest when A/C demand is greatest

Not necessarily. There are lots of hot summer days when the sky is cloudy.

Also, there can be direct sunlight heating up NYC while there are clouds over the solar plant, which could be miles away.

A/C isn’t just about resisting ambient temperature, but also solar gain.

About the latter, that’s where smart grids come in. Clouds move and it’s incredibly unlikely to be sunny but cloudy a few miles away for an extended period of time.

(Obvs don’t build solar where fog sits regularly).
