Australia is not a great example as no matter how cheap wholesale prices are, the consumer still gets destroyed by high electricity prices. It's a scam like most things in Australia.
Actually they are cutting you out. Some solar and all battery installations require a backdoor that allows the government to switch your network off at any time.
I'm sure they'll never use it for wrongdoings... but also they probably will.
It's a way to leverage the loads in certain areas but it's dreadful.
But yep. Solar is great for Australian homes. I still think it's weird that we had to solve electricity at the home level though..
