Abstract
Many developing countries on the equator, including Indonesia, have the potential for renewable and sustainable resources, such as solar energy. However, despite the enormous potential, the adoption level remains low. Previously, several studies discussed the potential, the feasibility, and the supporting policy of this technology, but none have been discussed from the customers’ perspective on a national scale. Therefore, this study attempts to determine the factors affecting the customers’ intention to use solar photovoltaics in Indonesia to develop a sustainable circular supply chain for renewable energy. This investigation was conducted based on integrating the unified theory of acceptance and use of technology 2 (UTAUT2) and the theory of planned behaviour (TPB). Furthermore, an online questionnaire was successfully distributed with a total of 208 participants. Structural equation modeling (SEM) was utilized to derive the causal relationships of the proposed hypotheses. The results indicated that price value (PV) has a positive relationship and a significant influence on attitude toward use (ATU), which leads to the behavioral intention (BI) to make the construct the most affecting factor. This is the first comprehensive study to analyze the intention to use rooftop solar panels based on the UTAUT2 and TPB framework. The successful approach to support photovoltaic use will bring less waste and strengthen the circular supply chain to support sustainable development.
Highlights
Introduction published maps and institutional affilThe sustainable development of developing countries is positively affected by renewable energy usage
The results showed that two constructs have a significant positive effect (p < 0.05), namely price value (PV) –> attitude toward use (ATU) –> behavioral intention (BI)
The results showed that price value (PV) had a significant positive relationship to attitude toward use (ATU), which subsequently led to the behavioral intention (BI) to use solar panels (β = 1.024, p = 0.014)
Summary
The sustainable development of developing countries is positively affected by renewable energy usage. A common understanding is that renewable resources in energy production are inversely proportional to their loss [1]. The use of renewable energy such as solar panels is consistent with the circular supply chain concept that recognizes future scarcity challenges [2]. A circular supply chain minimizes waste, thereby supporting the seventh sustainable development goal in ensuring access to affordable, reliable, sustainable, and modern energy for all [3]. A circular supply chain enables the amount of waste production to be reduced and ensures self-sustaining production systems. The necessity to consider a circular supply chain, which is part of the economic concept as climate change mitigation tools in sustainable development goals, has been confirmed [4]
