Abstract

This study investigates the design and performance of a grid-connected photovoltaic (PV) system for electric vehicle (EV) charging. The system utilizes 48 PV panels arranged in four parallel strings of 12 series panels each. A 25 kVA Huawei inverter converts the generated DC power to 24.3 kW AC, supplying the EV charger. A net metering system tracks both imported and exported energy, balancing the customer's needs by recording active and reactive energy in both directions. The proposed system provides the user with the ability to power their EV using solar energy. Design software (PVsyst, SketchUp, and AutoCAD) was used to create the architectural design, shading analysis, and electrical wiring diagram, including connection points and protection devices. Power consumption calculations for the EV were performed to ensure sufficient power supply from the PV system. Preliminary results indicate that the solar station can potentially generate 54 MW annually, resulting in cost savings of 9,375 K SAR and a return on investment (ROI) of 529.2%. The payback period is estimated at 7.2 years.
