PV integrated with EVs has become a promising way of utilizing PV generation in urban areas towards low carbon future. This paper aims to evaluate the technical and economic potentials of rooftop PV system integrated with EVs in 21 cities in Guangdong province, China, as well as the energy-economic-environmental effects of the PV+EV system, and shed light on how PV+EV system can be deployed within a region. The results show that PV+EV systems are cost-effective in all cities in the Guangdong province, EVs can increase the PV utilization in each city, making cities less dependent on external energy sources, reducing costs for the whole society, and providing more CO 2 emission reductions for most cities. However, cities vary in performance of PV potential and development capabilities, which should be taken into account in overall regional development plan.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
