Tracking Australia's progress in rooftop solar


The Australian Government’s Clean Energy Regulator tracks the number of small solar installations across the country.

'Small' solar may be used interchangeably with rooftop solar.


The CER publishes small-scale renewable energy installation data files, which include small generation units (small-scale solar panel, wind and hydro systems) and kilowatt (kW) capacity by installed postcode.

The data represents all systems that have had certificates validly created against them.
