Original abstract

The integration of home solar photovoltaic (PV) systems with electric vehicle (EV) charging infrastructure has gained more popularity with the advancement towards low-carbon electric vehicles and localized solar energy systems. Although the use of electric vehicles and solar PV systems has been widely researched, the integration of these two has not been studied much, particularly in the context of emerging economies' densely populated urban centers. Using the mixed-method, user-centric approach, the study has initiated the analysis with the use of focus groups with important stakeholders to identify the key factors for the integration of solar PV systems with electric vehicle charging infrastructure. Causal interdependencies are then formulated, and these factors are prioritized under uncertainty with the use of the multi-criteria decision-making framework, namely, Grey DEMATEL. The results indicate the key driving factors such as improved customer comfort, advancements in the use of renewable energy, and the availability of government incentives. Conversely, the barriers to the integration of solar PV systems with electric vehicle charging infrastructure are found to be the limited energy storage capacity, the lack of home charging infrastructure, and the lack of solar energy availability during off-peak hours. This study has highlighted the policy interventions to improve the solar PV charging barriers with the use of streamlined subsidies, effective public education, and advancements in technology, which could be useful for the wider acceptance of solar-powered electric vehicle charging infrastructure, thereby achieving the sustainability objectives.
