I've got solar. We switched things like pool pump, hot water and so on (things already on timers) from night to day.

Dishwasher can also gave a programmed start, so that can also shift from after-dinner to after-breakfast.

I also work some days from home, so other activities can be moved from night to day. We use a bore-hole for irrigation, laundry in the morning etc. Even cooking can often be done earlier in the day.

Aircon is the least problematic- when we need it, the sun is shining.

So yes, habits can shift. Obviously though each situation is different.
