This evaluation does ignore among the non-financial advantages of batteries. Crucially as Australia is experiencing increased frequencies of flooding and extra extreme bushfires many households are interested in batteries to offer back-up power within the occasion of the grid outage.

There can be the profit to the atmosphere to help within the discount in Australia’s reliance of coal-fired power stations. Batteries, and lots of of them, will likely be required if we’re going to eradicate fossil gasoline power in Australia altogether.
