The aerodynamic analysis of automotive vehicle play a vital role in deciding its overall performance and stability. The change in exterior vehicle body structure, affect drag and lift coefficient significantly. Also the variation of yaw angle affect vehicle performance significantly in terms of fuel consumption and stability. In the view of environmental concern and limitation of conventional fuel forced researchers to think about environment friendly alternatives. Using rooftop solar panel is an easy and convenient way to address this issue up to a certain extent. The objective of present work is to perform computational aerodynamic analysis of flat solar panel mounted mini bus model with 150 mm mounting height from roof at speed of 80 kmph. Also to investigate the effect of variation in yaw angles from 0 to 180 degree on vehicle performance. First numerical investigation is carried out to assess the impact of flat solar panel on the coefficient of drag of vehicle. To validate numerical result, the wind tunnel test is performed on scaled prototype model. The result shows the close correlation between experimental and numerical analysis. Further investigation carried out by considering variation of yaw angle. The result shows significant changes in drag and lift coefficient with respect to yaw angle.
