This report presents an assessment of the rooftop solar potential across Australia's housing stock. It has a particular focus on social housing, apartments and private rental housing - three sectors that are significantly under-represented in Australia's world-leading uptake of residential solar.

Solar is an excellent investment for almost all Australian households, but there are a wide range of savings, depending on the characteristics of household electricity consumption, retail tariffs and roof characteristics. Nevertheless, the majority of households installing a wide range of PV system sizes under different types of tariffs can expect a payback of between...

Deployment of rooftop photovoltaics (PV) is technically constrained by the availability of suitable roof space as well as by the ability of the distribution network to absorb exported generation. Although Australian rooftop PV installations are at record levels, deployment is uneven across different building types, with commercial, industrial and multi-occupancy residential buildings lagging behind the...

Despite potential advantages of load aggregation and scale discounts, few of Australia's 2.3 million apartment residents are amongst the country's 1.8 million solar prosumers. However, embedded networks can be used to distribute rooftop photovoltaic generation to households if split incentives and regulatory barriers are overcome.

Over 1.7 Australian households have taken the opportunity to generate some of their own power and reduce both their electricity bills and carbon emissions by installing rooftop photovoltaic (PV) systems on their homes. However, regulatory, technical, financial and organisational challenges have largely prevented Australia's growing number of urban apartment dwellers from accessing these benefits.
