Photovoltaic (PV) technology has recently proved its cost-effectiveness and low environmental impact in generating power. The key goals of this study are to develop a solar PV system for charging electric vehicles (EVs) while utilizing the residential apartment's current domestic power supply. This study focuses on modeling grid-interactive solar PV systems for charging EVs inside a 40-unit residential apartment complex. The Solar Pro tool is used to do the techno-economic analysis of the modeled PV system. The research investigates the installation of a rooftop solar plant devoted to delivering electricity to EV charging devices on a real-time five-story residential building. The performance of the PV plant is tested under a variety of scenarios, including EV loading, shadow mapping, and local meteorological conditions. The PV plant's size is optimized at 150 kW, taking into consideration economic aspects as well as the actual proportions of the structure. In addition, the MiPower tool is used to do a load flow study of the modeled system, which includes both the grid and the PV system. This research evaluates line losses, line loading, and voltage levels at each bus at maximum loading circumstances.

INTRODUCTION Charging of electric vehicles (EVs) using grid supply dominated by conventional energy sources is high and the purpose of rolling out the electric vehicle is completely defeated since conventional internal combustion (IC) engine-based vehicle during running condition emits carbon-rich gases in the atmosphere and it is powered by crude oil. To create an emission-free environment, technocrats brought vehicles that are powered by electrical energy which will not emit any carbon particles in the atmosphere and will not harm any living organism on the earth. Charging EVs is a challenging one since there is not enough charging station infrastructure available in the country. Due to a shortage of charging infrastructure, charging of EVs is done mostly through conventional fossil fuel-based energy sources which is again polluting the environment. Automobile companies in India started working on manufacturing the EV and research activities about EV sub-components were going in a rapid phase in the country. Even people started thinking about EVs due to zero emissions in the atmosphere and low running costs [1]. The EV charging infrastructure in India and it is a vision towards achieving 100% electric vehicle by 2030 was discussed in the paper. The Government measures in encouraging the establishment of EV chargers by private firms and incentives were elaborated by Kore and Koul [2]. The EV charging infrastructure feasible in the Indian market in terms of power quality,
