Good point I did not think about that that.There's a drawback to this plan if you have solar, which is that super off peak is midnight-2pm on weekends and holidays. Additionally, every day in March and April has an additional super off peak period from 10am-2pm. So that's going to reduce the value of your solar.
I didn't initially consider this, but I think I'll still save with EV-TOU-5.
We have 2 Powerwalls, so all solar power from 4-9pm goes to the grid at $0.54 per kWh. That is a 5.7x multiplier, which should help make up the difference.
