The first stuff was obvious. Our hot water and pool pump were already on timers so those were switched from night to day. Now on sunny days that's a free.
We've moved the dishwasher from night to day. The washing machine was already on day, so no change there.
We gave a small (5kva) battery so a chunk of our evening usage is covered.
There are a few other more subtle habits, harder to spot, and perhaps with more limited gains. Some random oven usage (for not-meal things) is more likely to happen during a sunny day,that sort of thing.
So yes habits have changed, and obviously our grid usage is massively reduced (by about 70%). But equally were not anal about it - things still run when they need to run.
