Abstract: Joint deployment of solar photovoltaic (PV) systems and electric vehicles (EVs) offers a sustainable option for decarbonisation. However, the possible influence of solar PV on EV uptake within a spatial-temporal framework is often overlooked in the literature. Based on a unique dataset at a detailed spatial level in Auckland, New Zealand, this study explores the potential complementarity of EVs and solar PV using spatial negative binomial regression models. We find evidence of complementarity between solar PV and EV uptakes. Results show that a one-unit increase in the installation of solar PV is associated with an increase in EV uptake count by a factor of 1.021. Households investing in solar PV also have the potential to accelerate EV uptake. Moreover, we find that a one-unit increase in EV charger installation in neighbouring areas is associated with an increase in EV uptake by a factor of 41. Charging infrastructure in neighbouring areas has a positive impact on subsequent EV adoption. Additionally, EV uptake is increased by 1.047–1.049 in response to a one-unit increase in early EV adoption, indicating that the early-adopter phase also positively impacts subsequent EV uptake. Our findings provide important insights for policy aimed at increasing EV uptake.
