Xenith's 26 glass solar panels have brought multiple industrial prototype technologies together to make one of the most efficient arrays the world has ever seen.
The solar array, with ultra-high efficiency silicon solar cells donated by the SunPower Corporation, employs a proprietary antireflective coating and cutting-edge glass from Corning. An extremely thin thermoplastic urethane is used as the elastomer for the array encapsulation.
With modest resources at their disposal, the Solar Car Project relies largely on students' hard work and donations from corporate sponsors.
Unlike some teams, which have vast resources and build cars costing well over $1 million, Stanford's Solar Car Project has built their vehicle for the 2011 World Solar Challenge for only about $250,000. The team expects it to cost about $49,000 to ship the car to Australia, drive the support caravan during the race, provide basic housing and food for the team, and buy supplies and parts for the race.
