If electricity is cheaper to generate when the sun is shining, the retail price of electricity should reflect that. In fact, the retail price should fluctuate minute by minute, so that demand can be shaped to match supply.
Trying to match variable supply to a fixed retail electric rate is certain to cause energy gluts and shortages.
For example, I'd be happy to charge my electric car during price minima, heat the electric water heater to the max when power is cheap, and run the A/C to the cold end of comfort when electrons are plentiful.
