ISU’s solar car team PrISUm finished their second day of racing on Monday—the team began the world’s longest solar car race Sunday in Austin, Texas.

The race, which is to last 10 days and is approximately 2,500 miles long, began at 8:30 a.m., and the first day’s drive went incident free, according to the team’s Web site.

Even though the day was overcast, Fusion, the solar car, still received 1,100 watts off of their stock array.

The team arrived in Weatherford, Texas with a fourth of their battery pack, but had it fully recharged by the end of the day, according to the Web site.

Fusion was the first stock car to arrive, with Auburn Univerisity’s team right behind them.

The teams are not scheduled to gather as a group again until they all reach Winnipeg, Manitoba, Canada, according to the North American Solar Challenge Web site. At about 2 p.m. heavy rain began and many teams were forced to wait. Team PrISUm made it just in time and avoided the rain.
