NOVELTY - The equipment has a space defined by a roof (8) and ground to produce heated air using solar radiation, where the roof is formed by juxtaposed roof modules each having a membrane (9) maintained at a regular distance from the ground. The space opens onto an exterior via an air discharge duct which rises up above the space along a natural relief, where the duct is formed of unitary ducts arranged one after the other and fixed to the ground. A turbine transforms kinetic energy of the air at a junction of the space and the discharge duct into electrical/mechanical energy.    USE - Used for producing electrical or mechanical energy from solar radiation and for greenhouse crop (claimed).    ADVANTAGE - The air discharge duct rises up above the space along the natural relief, so that it is supported by the relief, thus suppressing the technical constraints related to the construction of the duct with large height, while improving visual impact on the landscape. The roof defining the space is constituted by the juxtaposed roof modules, thus enabling the space to adapt its shape to a zone in which it is constructed for limiting damages on a site in which the equipment is implanted, as well as to adapt its extension according to the desired yield. The roof modules prevent the space from being subjected to instabilities related to compressed materials. The unitary ducts are arranged one after the other and fixed to the ground in order to form the discharge duct along the ground, thus permitting to adjust the length of the discharge duct based on the desired yield and altitude difference of the site. The elements constituting the equipment are made compact so as to facilitate their transport, thus facilitating the construction and demolition of the equipment.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following:    (1) a roof module for electrical or mechanical energy producing equipment    (2) a method for producing electricity.
