With the spread of carbon-neutral policies following the climate crisis, the supply of renewable energy worldwide has become very important and urgent. However, as of 2021, Korea''s renewable energy supply ratio is still at a low level among OECD member countries. Since 2019, the Korean government has been promoting energy transition policies such as establishing the national 3rd energy master plan, increasing the proportion of renewable energy, and strengthening the roles and responsibilities of local governmen
ts. As a result, the number of photovoltaic power generation facilities in the city continued to increase, but the performance was poor due to the difficulty in finding a site for the facility and the low acceptance of the residents. Therefore, this study tried to find the factors that hinder the acceptance of small and medium-sized photovoltaic power generation facilities in cities and the measures to increase residents'' acceptance in the consciousness of residents, the core actors of the local community, rather than existing measures such as technologies, systems, and budgets.
For this purpose, data were collected by conducting a questionnaire survey and face-to-face interviews with residents and stakeholders in Daedeok-gu, Daejeon. The causes and solutions of problems related to resident’s acceptability of the solar power facilities were identified through social network analysis (SNA) that can measure and visualize complex social structures.
According to the results of the study, the residents considered the installation cost and safety as the biggest obstacles to the supply of solar power facilities in the city, and they chose ''education and briefing sessions'' as the most effective and influential way to overcome the obstacles. In the survey on the preferred location of photovoltaic power generation facilities, in general, local residents had many proposals to install the facilities in open spaces and public facilities such as parks and idle areas. Based on the results of this study, it is necessary to expand the social value and function of photovoltaic power generation facilities in the local community. In order to supply and spread small and medium-sized photovoltaic power generation facilities in the city, it was found by the majority of residents that it would be very effective to systematically implement a resident-participatory local energy administration by installing a public/private governance organization such as a regional energy center. It is expected that the residents'' perceptions and views on the acceptance of photovoltaic power generation facilities revealed in this study will be actively utilized in establishing local government energy policies related to renewable energy supply, energy efficiency, and operation of local energy centers and systematizing governance. Furthermore, following this study, it is expected that follow-up studies for active energy conversion in local communities will continue.
