These maps are based on data from the Clean Energy Regulator, the Australian Government agency tasked with the administration of the Renewable Energy Target. Data from the Clean Energy Regulator is up to date as of 30 June 2024, however the number of systems installed may be understated due to the lag in system registrations.
For each postcode, local government area, and state electorate, the map shows the estimated percentage of houses that have a PV system and the total photovoltaic capacity installed.
Most of the PV systems in Australia are small-scale residential, and increasingly, commercial rooftop installations, which can be explored further via the PV Postcode Tool. There are also a growing number of larger-scale PV power stations with a capacity of 100kW or more. These power stations are indicated by individual markers on this map, and are detailed on the Large-Scale PV Systems page. Live performance data is available for systems in the Desert Knowledge Precinct in Alice Springs, and at the University of Queensland.
This map was created by correlating data from a number of sources:
Since Clean Energy Regulator data does not distinguish between PV systems installed on residential and commercial buildings, for the purposes of this map, we must assume a size threshold for residential systems.
The percentage of houses with a PV system shown on the map is estimated by comparing the total number of freestanding and semi-detached houses with the number of residential PV systems installed in each area.
* Where the percentage of houses with a PV system is over 90%, likely due to significant changes to postcode boundaries over time, we do not report the percentage of houses with a PV system. When negative rate of change in houses causes a negative number of houses or over 70% of houses with a PV system in the area, we disregard the rate of change and use the number of houses from the 2021 census without adjusting for decline.
PV installation data, aggregated monthly for each postcode, is made available for public download by the Clean Energy Regulator.
