Here is a solar plane that harnesses energy from the sun to fly. The Solar Plane V3 is built with Sunpower Maxeon cells which are more efficient and durable. The wings are extremely stiff with the ribs made of 1mm carbon fiber plate. The solar cells are not hard mounted to the wing, so they won’t crack when the wing flexes.
The wingspan is 10.5 feet while the wings weigh 1kg. The above video shows the solar plane in action.
