Smart grid rooftop solar electricity is a useful power resource and a viable alternative to conventionally generated energy. In the context of Vietnam, it could help people control their own source of electrical power and reduce power outages. This problem is expected to worsen in the future. Previous studies have shown that very few smart grid rooftop solar electricity systems have been installed by households in the Daklak Province, in the Central Highlands of Vietnam, and that as of 30th May 2019, only 18 out of 435,688 households had installed such a system. Moreover, only a small number of people knew about this resource. Based on previous investigations, this study proposed a research model that includes factors, which might affect the intention to instal smart grid rooftop solar electricity systems. However, the amount of money that people would be willing to pay (WTP) for the installation of such systems depends on their current electricity consumption. Therefore, to investigate this issue, a questionnaire was developed to survey 300 households in the Daklak Province, in the Central Highlands of Vietnam. A probit binary model was used to analyse the collected data from the questionnaire for this study. After interviewing the respondents from the 300 households in the research area and introducing into the concept and benefits of the smart grid solar electricity generating systems, they were more aware and knowledgeable of the concept. Thirty-three percent of households mentioned that they intended to instal such a system and were willing to pay between USD 1240 and USD 2220 for an appropriate-sized system based on their current electricity consumption and needs. Those households that possessed a high awareness of smart grid rooftop solar power were more likely to express the intention to instal such a system. However, it was also revealed that government incentives and household attitudes were important factors that influence the intention to instal such a system. In contrast, factors such as environmental concerns and the innovativeness of households were less influential. The awareness and understanding of the 309 households surveyed in this study regarding smart grid rooftop solar electricity systems and government incentives were the leading factors that affected the people’s intention to instal such systems. The majority of the respondents were willing to pay between USD 1240 and USD 2220 for installing such a system. In progressing this initiative in Vietnam, based on the results of this study, the Vietnamese government could identify those households that have the necessary degree of knowledge and awareness of such systems and offering incentives to instal such systems. The government could also develop communication programmes and other initiatives to enhance the understanding and awareness of the community of rooftop solar electricity so that programmes for the development of alternative energy sources could be more effective.

达克拉克省家庭安装智能电网屋顶太阳能电力系统的意图

智能电网屋顶太阳能电力是一种有用的电力资源，也是传统能源的可行替代方案。在越南的背景下，它可以帮助人们控制自己的电力来源并减少停电。预计这个问题在未来会更加恶化。先前的研究表明，越南中部高地达克拉克省的家庭安装的智能电网屋顶太阳能电力系统很少，截至 2019 年 5 月 30 日，435,688 户家庭中只有 18 户安装了此类系统。而且，只有少数人知道这个资源。基于以往的调查，本研究提出了一个研究模型，其中包括可能影响安装智能电网屋顶太阳能电力系统意图的因素。然而，人们愿意为安装此类系统支付的金额 (WTP) 取决于他们当前的用电量。因此，为了调查这个问题，我们开发了一份调查问卷，对越南中部高地达克拉克省的 300 户家庭进行了调查。概率二元模型用于分析从本研究的调查问卷中收集的数据。在采访了研究区300户家庭的受访者并介绍了智能电网太阳能发电系统的概念和好处后，他们对这个概念有了更多的认识和了解。33% 的家庭表示他们打算安装这样的系统，并愿意根据他们当前的用电量和需求为合适规模的系统支付 1240 美元至 2220 美元之间的费用。对智能电网屋顶太阳能发电意识较高的家庭更有可能表达安装此类系统的意向。然而，也揭示了政府激励和家庭态度是影响安装此类系统意图的重要因素。相比之下，环境问题和家庭创新等因素的影响较小。本次调研的 309 户家庭对智能电网屋顶太阳能发电系统的认知和理解以及政府激励措施是影响人们安装此类系统意愿的主要因素。大多数受访者愿意为安装此类系统支付 1240 美元至 2220 美元之间的费用。在越南推进这一举措时，根据这项研究的结果，越南政府可以确定那些对此类系统具有必要知识和意识的家庭，并提供安装此类系统的激励措施。
