1 Opportunities for increasing deployment of photovoltaics on multi-unit residential buildings in Australia Mike Roberts, SPREE PhD Research Project March 2015 February 2018 Supervisors: Dr Anna Bruce & Prof Iain MacGill CRCLCL Node of Excellence in High Performance Architecture 26/5/2016

2 Research Questions 1. What is the scale and nature of the opportunity for PV deployment on Australian apartment buildings and what are the barriers? 2. What are the household, network and societal benefits of different technical arrangements for deploying PV (and storage) on apartment buildings? 3. How can different financial, governance and regulatory arrangements increase deployment and realise the potential benefits of apartment PV? 6/8/2016 2

3 Technical Arrangements This image cannot currently be displayed. 6/8/2016 3

4 The Opportunity 14% of Australian population (Over 70% in Melbourne, Sydney, etc) 32% new residential development Low PV penetration Equity Issue % of common property load met by potential rooftop PV 72% of apartments are in buildings with 3 floors or less [2] where potential PV generation exceeds common property load [1] 6/8/ Roberts, M.
