L'avion solaire Electra One de PC-Aero réussit la traversée des alpes avec moins de 18 kWh. 

The emission and noise free flight was possible using 280 solar cells applied on the wing surface of the ultralight airplane and a 11.5 kWh battery package. The series production solar cells from the Solar World company in Germany provided about 30% of the needed energy. The maximum actual range of the aircraft is about 500 km.
