(1) Do approximately 30 per cent of owner-occupied dwellings have rooftop solar but only four per cent of rental properties?
(2) What data or information does the Government have about the proportion of rental residential properties with rooftop solar compared to owner-occupied residential properties?
(3) What incentives and support does the Government provide to support rooftop solar in residential rental properties?
(4) What assessment has the Government made of incentive programs in other jurisdictions?
(5) What further action will the Government take to reduce greenhouse emissions and energy costs in residential rental properties through rooftop solar?
(1) I am advised definitive figures on this question are not available. In 2018, public company EnergyLab reported nationally that 29 per cent of owner-occupied dwellings had rooftop solar installations, compared to four per cent of rental dwellings.
(2) I am advised the most recent available study showing the proportion of systems installed on owner occupied dwellings compared to rental residential properties is IPART's 2015 Household survey of electricity, gas and water usage. This showed that 95.4 per cent of the respondents with solar PV installed were householders that owned their home.
(3) - (5)
The Government's Home Energy Action program provides a subsidy of up to 50 per cent of the cost of rooftop solar and other energy efficiency upgrades for eligible social housing tenants. The Government is investigating other initiatives to support access to solar for other residential rental properties.
