We recently got solar panels and they work great but I want to run the tumble dryer at 2am. Is reasonable?

My wife is used to doing the laundry her way.

Run the washing machine and run the tumble dryer, one after the other.

Now with solar panels and we're on smart rate
Means it costs 9 cent per unit at 2 am.
But 33 cent per unit during the day.

My only request is that we run the tumble dryer at night.

I can see this becoming an issue because she has to change her ways.

Everything else, washing machine, dishwasher can run any time.

But tumble dryer is big use of electricity.
Am I reasonable?
