This study investigates the attitudes and characteristics of households in Hong Kong towards photovoltaic (PV) system adoption and evaluates the effectiveness of existing solar energy policy (i.e., the Feed-in Tariff scheme). A structured questionnaire survey was conducted to collect responses from 776 participants, including 371 PV installers and 405 non-PV installers. This study is distinct from previous studies by conducting a comprehensive quantitative analysis to uncover the differences in the financial, technical, social, environmental, and demographic aspects, as well as household electricity consumption patterns regarding PV adoption between PV installers and non-PV installers. This allows to address significant gaps in the literature that often focus solely on the perspectives of PV installers. The T-test results indicated significant differences in attitudes towards PV adoption between PV installers and non-PV installers in Hong Kong. Notably, PV installers were less deterred by the perceived barriers (e.g., PV installation cost and technical knowledge) and less attracted by the perceived motivations (e.g., peer effect and environmental impact) than non-PV installers, whereas non-PV installers were more likely to perceive barriers and motivations than PV installers. Chi-square tests of independence revealed that demographic factors (e.g., homeownership, housing type, household income, education level) were the main determinants of PV adoption. Specifically, PV adoption was positively associated with homeowners, independent houses, medium to high income (i.e., HK$40,000 to HK$59,999) and a high education level. In addition, the decision to install PV systems was also influenced by overall annual electricity consumption patterns. Therefore, it is imperative for policymakers to implement targeted interventions to effectively strengthen PV uptake and pave the way for a more inclusive and sustainable transition towards widespread PV adoption.

香港住户对采用光伏发电的态度和特点:确定可持续能源转型的决定因素
本研究调查了香港家庭对采用光伏 (PV) 系统的态度和特点,并评估了现有太阳能政策(即上网电价计划)的有效性。进行了一项结构化问卷调查,收集了 776 名参与者的回复,其中包括 371 名光伏安装商和 405 名非光伏安装商。本研究与以前的研究不同,它进行了全面的定量分析,以揭示光伏安装商和非光伏安装商在财务、技术、社会、环境和人口方面以及家庭用电模式的差异。这样可以解决文献中通常只关注光伏安装商观点的重大空白。T 检验结果显示,香港光伏安装商和非 PV 安装商对光伏应用的态度存在显著差异。值得注意的是,与非光伏安装商相比,光伏安装商较少受到感知到的障碍(例如,光伏安装成本和技术知识)的阻碍,也较少被感知到的动机(例如,同伴效应和环境影响)所吸引,而非光伏安装商比 PV 安装商更有可能感知到障碍和动机。独立性卡方检验显示,人口因素(例如,房屋所有权、住房类型、家庭收入、教育水平)是 PV 采用的主要决定因素。具体来说,PV 采用与房主、独立房屋、中高收入(即 40,000 港元至 59,999 港元)和高教育水平呈正相关。此外,安装光伏系统的决定还受到年度整体用电量模式的影响。 因此,政策制定者必须实施有针对性的干预措施,以有效加强光伏的采用,并为向广泛采用光伏的更具包容性和可持续性的过渡铺平道路。
