Swiss experimental aircraft

long-range solar-powered aircraft

SolarStratos is an aeronautical project aimed at flying a piloted solar-powered airplane for the first time to the stratosphere. The SolarStratos airplane is equipped with solar cells but is not able to fly directly on solar power, thus is accurately described as a battery powered electric airplane that is equipped with solar cells; it is planned to be the first crewed solar-equipped aircraft to enter the stratosphere.
