Factors Affecting the Willingness to Install a Solar Photovoltaic System - A Case in Vinh Long City, Vietnam

Abstract

The solar energy was received great support from Vietnamese Government by the Decision No. 11/2017/QD-TTg on incentive mechanism for solar power projects development. However, the installation of solar photovoltaic systems is rather low recently. This study assesses several variables affecting the willingness to install a solar photovoltaic system. A randomly survey was conducted at 180 households in Vinh Long city of the Vietnamese Mekong delta that using a five-scale Likert questionnaire. For the socio-demographic features (gender, aging, education, income), the income of respondents is significantly different but negative correlation to the eagerness to install a solar photovoltaic system. Within respondents’ perceptions (usefulness, environment, risk) and influences (society, policy, finance), variables of finance and policy are statistically association to the motivation to install a solar photovoltaic system, but their correlations are in opposite direction. The study also found that solar power information should broadly disseminated to the local community so that people can gain more knowledge on this renewable energy source.
