Abstract

In this study, we predicted the energy generation of a solar electric vehicle during driving by considering the tilt angle of the solar modules and various driving conditions. The experiment was conducted in the Pukyong National University area, where an experimental route was established to allow driving along all four cardinal directions. For the experiment, solar modules, along with a device for adjusting their tilt angle, a pyranometer, and a 360-degree camera were installed on the roof of the vehicle. Hemispherical images were captured at 35 locations along the experimental route, and the annual direct and diffuse irradiance reduction ratios were calculated. The energy generation was predicted by varying the tilt angle of the solar modules from 0° to 45° in 15° increments at 09:00, 12:00, and 15:00 local time, and the prediction accuracy was verified through a driving experiment conducted in November. At 09:00 and 15:00, the highest irradiance was measured when driving westward and eastward, respectively, opposite to the sun’s direction, and the measured irradiance increased as the tilt angle of the solar modules increased. At 12:00, the highest irradiance was observed when driving northward, and similarly, the measured irradiance increased with larger tilt angles of the solar modules. A comparison between the predicted and measured energy generation at the 35 experimental locations confirmed that the variation patterns in prediction and measurement were consistent under different solar module tilt angles and driving conditions.
