The 17,000 solar cells built into the wings harness the suns energy, allowing it to fly through the night.用碳纤维材料生产的单人座“太阳能动力2号”翼展为72米，多达波音747，重量则仅有相等于一辆汽车。加装在机翼上的1万7千个太阳能电池储存能量，以供夜间飞行中。

The Si2 took 12 years to build and is the brainchild of two Swiss scientists - Bertrand Piccard and Andre Borschberg.生产“太阳能动力2号”费时12年。设计者是瑞士科学家皮卡德和博奇伯格。
