10 days of solar: Australian rooftops can host up to 61GW of rooftop solar

Published by

A new report produced by Solar Citizens in collaboration with the researchers at University of New South Wales (UNSW) in the school of Photovoltaic & Renewable Energy Engineering and the Australian PV Institute(APVI) estimates there is potential for up to 61GW of PV installations on Australia’s residential rooftops.

Most of this potential (93.5 per cent) is on houses, but some (about 6.5 per cent) is on apartment buildings. We have only fulfilled about 6GW of this 61GW residential PV potential, and many of the 78.4% of houses with unutilised roofs could host arrays.

In addition to the unrealised potential on dwellings without any solar, many houses with PV could also upgrade to host a larger system. But even with room for improvement, Australia leads the world in household PV uptake with 21.6% of homes installing systems.
