6,500 home battery systems were installed across Australia in 2016. In the first half of 2017 alone that number has jumped to 7,000 - with analysts predicting at least 20,000 battery installations by the end of the year.
The cost of battery system installations has dropped - mainly due to increased competition among wholesalers - but only by five per cent. So what is causing the sudden and significant uptake? The rising cost of electricity, apparently.
