Abstract – The increasing trend of the energy consumption of humanity have brought forward the efficient use of current energy resources and seeking for adaptation of renewable energy resources. Intergration of renewable energy into transportation, on the other hand, has crucial importance as it reduces the emissions in the urban regions and increases the life quality by reducing the noise in solar-powered electrical vehicles. Solar-powered vehicles, automobiles or planes, with photovoltaic panels (PVPS) are widely in use for decades, however, there are several aspects, such as electrical conversion and storage efficiencies, that should be improved. It is known that increasing the temperature of the PVPs adversely affects both the panel lifetime and electrical conversion efficiency. In this study, a 3D CFD model of a solarpowered racing car is developed in ANSYS-FLUENT to investigate the power outputs of the PVPs on the varies positions of the vehicle under various speeds, 30 km/h to 120 km/h, and irradiations, 300 W/m2 to 900 W/m2.
