The global shift towards sustainable energy practices underscores the importance of residential photovoltaic (PV) adoption, a trend that has been gaining more attention in Hong Kong. Despite this, existing research in this area lacks quantitative analysis, with a particular deficiency in statistically robust surveys across diverse residential sectors in Hong Kong and in comparative studies between PV installers and non-PV installers. Addressing these gaps, this study employed a comprehensive questionnaire survey to collect data from a representative sample of both PV installers and non-PV installers regarding their housing types and homeownerships, followed by chi-square tests of independence to explore the demographic distinctions influencing residential PV adoption. The findings highlight significant variance in adoption rates between homeowners and tenants, with a noticeable inclination for PV installation among owners of independent houses. In contrast, co-tenants in residential flats demonstrated a lower propensity for PV adoption. These insights provide a crucial understanding of the factors that affect PV system uptake and could inform the formulation of targeted policies to boost renewable energy integration in urban residential settings.
