How much rooftop solar can be installed across Australia?

A recent study by the Institute for Sustainable Futures (ISF), the School of Photovoltaic and Renewable Energy Engineering (SPREE) at UNSW and the Australian PV Institute (APVI) believe Australia could be a lot more solar reliant than we currently are.


In total, Australia has the capacity to install 179 gigawatts of solar energy.


To put this into perspective, that is over twenty times more than the total capacity of all small-scale (residential) solar power systems currently installed in Australia (~8.6GW – Clean Energy Regulator, April 2019).   


These figures do vary though, with the Australian PV Institute (APVI) reporting over 10GW in small-scale solar capacity across Australia, with a growing installation rate of about 15,000 systems per month.


According to APVI’s report, Australia is experiencing a rapid rise in solar installations, with the nation now having over 2 million solar installations. Source:


The Clean Energy Regulator predicts that we now have over 600 million panels across Australia, translating to about 24 panels for every person living here. 


Where can we install the most solar energy?


Recognising Australia’s love for the detached home, it doesn’t come as much of a shock that residential solar installations pose for the greatest amount of solar potential.


According to the report, residential Australia dominates the national solar potential, with over half of the total coming from the residential zone.

The residential zone for Australia has the potential for almost 100GW. In relation to how much energy this truly is, just 1GW has enough energy to power around 700,000 homes.
