This here's a collection of Solar Roadsters from various years of the Utah Solar Racing League, a competition held on the Utah salt flats to see who can built the fastest, most efficient, and most stylish solar-powered vehicle. These particular vehicles are from the Roadster-class, meaning they can reach speeds of up to 140 miles per hour on a single charge. Racers are allowed one large main panel and one auxiliary panel to power the motors and electronics. The cars get one 8-hour charge during the early morning, which is when the style judging portion of the contest takes place. During the noontime, the cars finally get to speed across the salt flats, where their speed and efficiency are measured by stations along the straight course. The large main panel must be disengaged from the battery or covered up, however the auxiliary panel can be connected to the battery or the electronics to power them during the race. These roadsters are currently on display in the Petersen Automobile museum in California.
