Abstract: A flexible shadow-generating wind-energy device intended to provide solar protection is provided, the device using the kinetic energy of the wind in order to be supported in the air and project a shadow. The device is formed by a panel or group of panels and one or more beams, which together define a bow edge, a stern edge and sides. The device has flaps that provide stability and are used to anchor same to the ground. The device operates as follows: the panel or panels together with the flaps and the beams surround a moving air mass; the aerodynamic forces generated are sufficiently strong to support the device in the air; the device is maintained anchored to the ground; with the device anchored to the ground, it can be maintained at a pre-determined height and project a shadow on a surface below.
