Urban decarbonization is a crucial step for China to achieve the goal of carbon neutrality. It is essential to adjust the energy structure and increase the proportion of new energy in the energy structure for cities. This paper aims to construct a technical and economic model to evaluate the emission reduction potential and economic impact of the photovoltaic (PV) and photovoltaic plus electric vehicles (PV+EV) systems in Shenzhen city. It is found that both systems can reduce emissions, the PV+EV system can reduce carbon emissions by up to 45%, and the costs can be reduced by 25%. The construction of this system is cost-effective for achieving the carbon neutrality target.
