Of course if the more solar we get combined with cheap computing a market will emerge where there are two prices of electricity. Car charging will probably be first where they turn on/off depending on the solar output. Refrigerators and AC could follow.

In the UK we have Economy 7 which offers lower rates at night. https://en.wikipedia.org/wiki/Economy_7.

It's generally used in homes with 'storage heaters' which heat up overnight and release heat during the day while you're out at work. https://en.wikipedia.org/wiki/Storage_heater

I think we are more talking about hourly prices. You should take a look at the electric market, prices fluctuate heavy. So heavy even in some countries, that you are PAYING when you put electricity on the net: http://www.elia.be/nl/grid-data/balancing/onevenwichtsprijs

You can already charge your EV for less if you let the utility modulate the charge rate to match their demand/supply.

In areas where the utility is not set up to do this, you can programming it to monitor the grid and prefer charging when the grid is less carbon intensive.

Bit of a problem if you have to do that "turn of electric car charging" if you have a non trivial number of electric cars.
