The federal government led battery rebate continues to be enormously popular, with the total number installed with existing or new rooftop solar systems now at 43,517.
“Solar battery installations aren’t showing any signs of slowing down,” the Clean Energy Regulator says in its latest update, which points to an additional 23,925 solar batteries installed since its July update.
The CER says these solar batteries have provided a total nominal capacity of 825 MWh, or more than six times more than the original Tesla big battery at Hornsdale, which was installed in 2017 and was the world’s first.
It says the average nominal battery size installed is 19.0 kWh.
What is interesting abut the date is where they are being installed, and which states are installing the biggest batteries.
The first table above shows that NSW leads in absolute numbers, with 15,418 solar batteries installed, but South Australia – where rooftop solar systems are already on half of all homes – likely has the highest per capital with 6,415 installed to date. That is nearly as many as Victoria.
The Northern Territory may have the lowest number, just 145, but it has the highest average by size – 24.8 kWh – with Queensland following next at 20.7 kWh. Tasmanians are choosing smaller systems, with an average size of 16.5 kWh.
