This paper discusses the design of a solar parking lot in the off-grid mode for charging 20 Electric vehicles for Newfoundland condition. The selected site is near the Canada National Research Council (NRC) building located in the Memorial University of Newfoundland St. John's, Newfoundland, Canada. Smart EQ ForTwo was considered as the electric vehicle (loads) for the design. For the selected site, a system is optimized using homer software. The proposed charging infrastructure is equipped with current sensors that communicate the power generation data and power consumption data in real-time to the cloud for direct PV run or utilize the excess power stored in the battery bank. The decision is made to charge the connected EV using an algorithm that makes use of the data, sent by the sensors with the help of IoT. Complete system design and simulation results are presented in the paper. Keywords-PV, Electric Vehicle (EV), Renewable energy, IoT (Internet of Things), solar energy.

... Thus, in the context of integration with renewable energy sources, such as photovoltaics, BEVs' batteries could store the solar energy available during the day when BEVs are parked [5][6][7] and then restore part of the energy in their batteries into the grid during evening peak-demand hours. Multiple studies worldwide (from Canada, the United States, Brazil, Europe, Asia, and Africa) on the feasibility of these new attributes of BEVs have been discussed in the literature [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. ...

... The study has shown a reduction in daily power demand of 64.24% for conventional stations. Meanwhile, in St. John's, Canada, a study was based on an off-grid carport for 20 EVs [30]. With an average of 3.15 kWh/m 2 /day, around 34 strings with 10 PV panels in each string rated at 340 W were used to provide 115.8 kW. ...
