Abstract:

This study contributes to the literature on this topic by investigating the factors influencing the co-adoption decision among EV owners in California, a leading market for the two complementary technologies. A California cohort survey of EV owners revealed differences between co-adopters and EV-only households due to sociodemographic characteristics, economic factors, and access to charging capabilities. These factors influence the intention of current EV-owners to adopt PV or not in the future, highlighting the importance of considering these factors when evaluating EV adoption.These findings raise important policy questions regarding incentive needs to improve affordability and address equity issues as well as the need for pricing mechanisms at the utility level and by charging service providers to encourage co-adoption among EV owners.
