I think where it might help is that time when the notch of power consumption matches the peak of power production: the middle of the day.

That is the time when a car parked in the hot sun causes the internal A/C to run to keep the car cooler.

Telsa cars will run the A/C when the internal temperatures reach 105°F (configurable)

This might be a good time to counterbalance the battery loss with the solar power peak.
