With all the HVAC threads, though that I'd add another.
I'm moving in just under a month, and thus am back in the realms of having a mortgage, so with the opportunity of having someone else's money to spend, and having a pact with my wife that this is the house that we retire into (15 yearsish), we have been considering all things.
Electricity is currently 30c+/KWh, and with energy trends in Australia clearly isn't going to get cheaper. Off peak is around 10c, but clearly going to rise as the peak gets iunverted.
Solar is on probably 1:10 roofs in the district, and you get around 8c feed in tarriff, but we are a working family, and so would be generating the best while at work, and sucking it the hardest in the hours coming home from work.
My employer sells Tesla Power Wall 2, and another Aussie system "Redback", which combines batteries and time of use controllers...e.g. at the point that you are about to start exporting, it can switch on a hot water service for example, or a washing machine/clothes drier.
In my machinations, I've come across this...

If you have access to off peak/solar, you freeze the "ice battery", then use the stored cold when you need to, either through direct access, or as the cold sink for an existing A/C system.
