The number of solar batteries since the start of the cheaper program for the federal government’s battery continues to increase. See the latest figures from the Australia Clean Energy Regulator (CER).
How many solar tab were installed?
The CER reported last week that a total of 43,517 house batteries with a new or existing solar system had been installed on the roof since the start of the discount on July 1, 2025 to the end of August. Represented 825 MWh nominal capacity.
- July installations: 19:592
- August installations: 23.925
At the end of the last month, the Federal Minister of Climate Change and Energie Chris Bowen said that 40.004 sun batteries were installed in just 8 weeks as part of the program, so that in the last days of August it was quite an increase.
The average battery capacity also continues. Before the scheme, the average nominal capacity was 11 – 12 kWh. In July this rose to 18.2 kWh and increased 19.2 kWh again with the installations of August.
The numbers of the CER include installations with approved and outstanding applications for small technology certificates (STCs) as part of Australia’s small scale for renewable energies (SRES) 1, but not those with failed STC applications or those that have not yet been used. STCs can be created under the SRES up to 12 months after installation, not so many installers would hold back. The Clean Energy controller has previously pointed out that the processing of STC claims gives a little behind.
NSW still leads to installations
New South Wales continues to lead the states and territories with 15,418 installations, followed by Queensland (8.572) and then from Victoria (6.945).
Nt is the average capacity, but ..
The Northern Territory still leads the pack on average: a whopping 24.8 kWh; Followed by Queensland (20.7 kWh) and New South Wales (19.6 kWh). However, it is worth noting that the number of installations in NT is tiny compared to all other countries and territories.
Consider the “Big Tank” battery carefully bargains
Apart from the generous battery discount of the state battery, part of the increase in the average capacity will advance.
For example (and this is not a recommendation as such), a 30 kWh Voltx Energy bytewatt Neovolt Battery System (3 x separate units) is offered with a 5 -kW -NOVOLT -HYBRID interference from 5,920 US dollars, including standard installation in New South Wales, South Australia and Queensland. “However, additional fees can apply for security protection”, and Backup is a very practical thing.
Another, even cheaper offer that we saw, was a 51.2 kWh dyness Battery Powerbox Pro system, also with a 5 -kW inverter, of only 5,100 US dollars as part of a group purchase. The latest round is over.
But as Solarquotes’ internal veteran installer Anthony Bennett pointed to this specific deal:
“An average whole day sunshine to 6.6 kW solar only fills half of the battery. Or charging out of the grid that sweats out of the ass, the inverter takes 10 hours. As soon as you are filled, you cannot extract the energy very quickly: 6 kW to run the toaster, kettle and dishes despite the grid, despite the grille, you would still be out of the grid Insert a grid from the grid. “
It would also be necessary for an important place for installation, since the system is not only a solar battery, but five separate 10.24 kWh units.
Anthony’s general rule of thumb is a 2- or 3-to-1 ratio for battery and inverter size. With a 5 kW inverter, an appropriate capacity would be a 10 kWh or 15 kWh battery.

- The SRES is the vehicle for the national discount of the battery (and solar) discount, and STCs are what the discounts are based on. While the discount is offered as a discount in advance, installers or their agents can only create the certificates after installation. ↩
