The aircraft can fly at an average speed of 70 km/h (43 mph), takeoff at a speed of 44 km/h (27 mph) and attain a maximum cruising attitude of 8,500 m (27,900 ft). This high energy density enables the Solar Impulse 2 to store more energy without increasing the plane’s weight or size. —André Borschberg. Source: Kokam.
