Home batteries in Australia

Small-scale battery systems registered with the Clean Energy Regulator, by month of installation. The CER publishes battery figures by postcode from Jul 2025; earlier months are not collected in this dataset, which is not the same as zero.

Data to Sep 2026. Oct 2025 onward is provisional.

Why recent months are provisional

Installations can be registered with the Clean Energy Regulator up to 12 months after they happen, so figures from Oct 2025 onward will rise as late registrations arrive; earlier months can also be revised. A month-to-month difference is not the number of new systems installed in that month.

National figures on this site are the sum of the CER postcode rows for every valid postcode (postcode 0000, which the CER uses for invalid entries, is excluded). They are not an official CER national total.

Battery installations by month, Jul 2025 to Sep 2026Every month the CER has published. Filled spokes are final; outlined spokes (from Oct 2025) are provisional.

Total since Jul 2025: 546,789 installations and 15,287,745.8 kWh of usable capacity.

Usable capacity is the energy a battery can store, in kilowatt-hours (kWh). It is a different unit from solar capacity (kW) and the two are never added together on this site.

Coverage, symbols, caveats and source files

Coverage. 2,810 postcodes with CER solar records across Australia. Suburb names are not in the CER files and are not shown.

  • Provisional May still be revised; outlined, not filled.
  • Not collected The source did not collect this; grey.
  • Not published No value released for this cell; a gap, never zero.

Things to know

  • Months from October 2025 are provisional: installations can be registered up to 12 months late, so these figures will rise.
  • The CER publishes battery figures by postcode from July 2025. Earlier months show “Not collected”, never zero.
  • An installation can be a new system, an extension or a replacement, so counts are not the number of homes with solar.
