Resident's Issues and Interactions with Grid-Connected Photovoltaic Energy System in High-Performing Low-Energy Dwellings: A User's Perspective

Solar PV systems have become common-place in many cities and regions, and is a core technology in purpose-built low-energy homes, but evidence is emerging that in many cases electricity output may be significantly lower than expected. Information from in-home energy monitoring systems, interviews and informal discussions with residents has shed some light on the experiences and issues faced by the end-user, particularly those associated with operating a solar PV system to achieve a low-carbon lifestyle. Case studies of residents in different ownership and income situations, and from three distinct housing developments in Australia and England are used to highlight end-user experiences. The study finds that the residents face a range of issues including the initial sizing and commissioning, a lack of solar knowledge and expected generation performance, as well as regulatory barriers that limit the opportunity to upgrade system size.
