Shadows cast onto the array can drastically lower the car's power supply. If a shadow falls upon one cell, it will cause the entire panel to lose power. Therefore, the team has installed diodes to bypass that cell so that the rest of the panel continues to function.
An in-house-developed program called Shellpower simulates the sun's angle and the amount of power Xenith will generate at every point during the day while racing across Australia.
Strategy team leader Dan Posch imported Xenith's body design into Shellpower's 3D visualizer, and uses the program to look at the shadows cast on the car at different latitudes.
Using that shading information, the team ultimately decided on an efficient bypass scheme that would allow Xenith to generate the maximum amount of power throughout the entire race day.
