SOLAR MODULE WITH CONCENTRATOR (VERSIONS) Russian patent published in 2012 - IPC F24J2/14 

FIELD: physics.

SUBSTANCE: in a solar module with a concentrator, whose reflecting surface is symmetrical relative a plane of symmetry passing through the centre of a receiver perpendicular its surface, the reflecting surface is formed by rectangular mirror plates - facets which, between two planes passing through parallel planes of symmetry of the edge of the receiver and forming a dihedral angle α equal to a given aperture angle, are placed such that the plane of the facets and the plane passing through the near edge of the receiver and far from the plane of symmetry of the receiver and the edge of the facet far from the plane of symmetry, form a right angle, and the other facets are placed such that the beam passing from the side of the plane of symmetry at an angle to it which is equal to half the aperture angle α/2, after reflection and refraction on the edge of the facet far from the plane of symmetry, falls on the near edge of the receiver if said edge of the facet is lower than the plane of the receiver, or on the far edge of the receiver if the edge of the facet is higher than the plane of the receiver. In another version of the solar module, the reflecting surface is formed by rectangular mirror plates - facets which, between two planes passing through parallel planes of symmetry of the edge of the receiver and form a dihedral angle α equal to a given aperture angle, are placed in form of a chord of circular cylindrical surfaces with radii equal to half the width of the receiver, whose axes coincide with the edges of the radiation receiver and are parallel to the plane of symmetry, and the other facets are placed such that the beam passing from the side of the plane of symmetry at an angle to it which is equal to half the aperture angle α/2, after reflection and refraction on the edge of the facet far from the plane of symmetry, falls on the near edge of the receiver if said edge of the facet is lower than the plane of the receiver, or on the far edge of the receiver if the edge of the face is higher than the plane of the receiver. In the two versions of the solar module, in the photoelectric detector, only those solar cells whose centres lie on a single line parallel to the plane of symmetry are electrically connected in series, and each row of series-connected solar cells has a blocking diode.

EFFECT: high concentration factor, high annual average energy production and low cost.
