SolarStratos is equipped with 22 sq m (237 sq ft) of solar panels. These charge a 20 kWh lithium-ion battery pack, which powers a 32-kW electric motor that in turn drives a 2.2-m (7.2-ft) propeller.

The SolarStratos plane is powered by 22 sq m (237 sq ft) of solar panels and will be flown to an altitude of 25,000 m (82,000 ft) to demonstrate and explore the potential of the technology.

The SolarStratos team expects the commercial, two-seater plane to hit the skies in 2018 without the use of “large quantities of energy or helium” it’d usually take to reach space.
