| Summary/Abstract |
Rooftop solar photovoltaic (PV) systems present households with a way to reduce their energy bills, while contributing to a clean energy transition. However, rental properties are considerably less likely to have solar PV. It is unclear whether current policies that focus on reducing upfront costs to installing solar PV address the barriers perceived as most important by property investors. Using a best-worst scaling survey of 931 property investors, we find that investors on average view renters being unwilling to pay higher rents for properties with solar PV equally as important as affordability concerns as barriers to investment. Owners of apartments or townhouses focus on structural barriers. Our discrete choice experiment of 147 property investors shows that policies that spread solar system payments over time and direct feed-in tariff revenue to property investors are not preferred by most owners of fully-detached rental dwellings. We conclude by stressing the importance of policies that reduce information asymmetries from the property investor perspective regarding the value that renters place on PV systems. There is also a need for policies to better address barriers faced by owners of apartments and townhouses.

| Summary/Abstract |
Rooftop solar power production is particularly relevant to climate change mitigation in Australia given the country's high insolation rates. However, residential adoption rates vary across the country with potential for increasing uptake, particularly on apartment buildings and rental properties. This study focuses on past and future motivations for the adoption of rooftop solar panels and the barriers people perceive upon adoption. An online survey was conducted with 1126 respondents across Australia showing that 65% of those who had no solar panels were intending to adopt them. Results of best-worst scaling showed that motivations for past and future adoptions did not differ significantly and that economic motivations predominated, particularly for homeowners. Renters, a group often overlooked in the production of solar energy, strongly desired solar panels, often for environmental reasons, but were discouraged by uncertainties about the costs and benefits of installing solar. This reveals a need for policies that help renters and landlords, and those in multi-unit dwellings, to find ways in which the costs and benefits can be shared equitably. This will become more important as energy costs rise and urbanisation intensifies.
