Every month we publish small-scale renewable energy installation data files.

These data files provide a list of:

  • small generation units (small-scale solar panel, wind and hydro systems) and kilowatt (kW) capacity by installed postcode
  • solar water heaters and air source heat pumps by installed postcode.
  • solar batteries and useable kilowatt-hour (kWh) capacity by installed postcode.

The data represents all systems that have had certificates validly created against them. The data includes new installations, upgrades to existing systems and stand-alone (off-grid) systems.

This data is not publicly available via the REC Registry and does not include systems that are pending registration or have been failed.

Note: A 12-month creation period for registered persons to create small-scale technology certificates applies under the Renewable Energy (Electricity) Act 2000. Therefore, figures for the current and previous year will continue to rise due to the 12-month creation period.

Total investment in wind and solar generation capacity, including Small-scale Renewable Energy Scheme capacity for 2016 to the present is available under large-scale renewable energy data.

Summary of postcode data

This data is current as at 31 October 2025.

Solar battery postcode data

Solar battery postcode data is only available from 1 July 2025, when solar batteries became eligible under the Small-scale Renewable Energy Scheme. Postcode data only includes installations that have had their application for small-scale technology certificates approved. It does not include installations with pending applications.

Data for batteries installed at the same time as a grid-connected solar PV system that was provided on a voluntary basis before 1 July 2025 remains available as historical information and will no longer be updated.

Small-scale installations by installation year

There is a total of 6,232,972 small-scale installations. This includes solar batteries installed under the Cheaper Home Batteries Program that started on 1 July 2025.

Description

This data is based on voluntarily disclosed data for batteries installed at the same time as grid-connected solar PV systems from 1 September 2014 to 30 June 2025. It is no longer being updated.

From 1 July 2025, solar batteries became eligible for small-scale technology certificates under the Small-scale Renewable Energy Scheme. Our monthly postcode data publication includes solar battery installations from this date.
