Drivers Affecting the Adoption of Solar Photovoltaic Technology: A Case Study of Vietnamese Households

Abstract

This study used the Theory of Reasoned Action (TRA) to examine and predict the adoption of solar photovoltaic systems by Vietnamese households. The research examined various factors, including perceived risk, perceived benefit, government incentive policies, environmental knowledge, environmental concern, attitudes, and subjective norms, that influence the intention to adopt solar photovoltaic technology in Vietnam. It was based on a survey of 358 household representatives from urban areas in Southern Vietnam. Participants answered questionnaires rated on a 5-point Likert scale. The data collected were analyzed using Cronbach’s Alpha, Confirmatory Factor Analysis (CFA), and Structural Equation Modeling (SEM). The SEM analysis confirmed both positive and negative relationships within the model. As a result, the study provides essential recommendations to significantly increase the adoption of solar photovoltaic technology in Vietnam, address the primary barriers, and capitalize on opportunities for faster growth.
