TTM Australian's are already the biggest users of solar per capita.

The take up of batteries is expected to be huge and why Tesla is targeting Australia
It is going to be HUGE and Lithium is going to be in very short supply.

The Climate Council also found half of all households were predicted to adopt solar systems with battery storage, with the market potentially growing to $24 billion.

Mr Stock said the technology would be disruptive to existing network operators, and some companies were already altering the way they priced power to discourage solar and battery combinations.
"This is perverse, because battery systems, coupled with PV, can actually help networks get much better use out of their assets by smoothing out the demand on the grid," he said.
"That should mean that network companies don't need to invest anywhere near as much at adding capacity in the future, and they get better use out of the existing capacity."
In May, AGL, which owns Victoria's biggest brown coal generator, Loy Yang, announced it would market its own battery.
It has also begun offering customers solar panels without upfront fees.
"It's really important that the traditional players in the industry see this as an opportunity instead of a threat, because if they look at this as an opportunity they'll be thinking 'how do they leverage this technology into their businesses?'" Mr Stock said.
"If they see it only as a threat, that will put back Australia [from] potentially being a leader in the uptake for up to a decade, and I'm not sure we as a country these days can afford to put ourselves in a position where we're a laggard, when we could be a leader."
