The invention relates to the field of solar technology, in particular for manufacturing solar installations with solar concentrators for the generation of electricity and heat.

Known solar installation with a hub comprising a cylindrical hub receives sunlight plane, the cross section of the hub is made of a circle of radius r, and the radiation receiver with bilateral working surface located in the plane of radius r (French patent 2342558, publ. 23.09.77, MKI H01L 31/08, G02B 5/08). Solar radiation comes on the receiving plane, which includes a portion of the radiation receiver, made in the form of solar cells with bilateral photosensitivity, part of the solar radiation falls directly on the front side of the radiation detector located on the receiving plane within the radius r. Through the second part of the receptive plane with the size of r, the radiation passes to the hub, is reflected and goes to the back side of the radiation detector. Concentrations (geometric) radiation on solar cells, equal to the ratio of the area receptive plane (2r) to the area of solar cells (r), in this case is 2.

A disadvantage of the known solutions is the low concentration of bat is to use solar cells, which in the ideal case equal to 2, while in real terms taking into account the reflection from the cylindrical hub is 1.5-1.6, which leads to a slight change in the cost characteristics of the module (PV module)and thermal parameters (for combined modules) to generate electricity and heat.

Known solar installation with a hub comprising a cylindrical hub receives sunlight plane and the radiation receiver with double-sided work surface, whose cross section cylindrical hub made two radii, and circumference of radius r is mated with a circle of large radius R in the plane, on which the centers of both radii perpendicular to the plane receiving the radiation. The radiation detector may be located in the plane of radius r, perceiving combined with the plane of the pair of circles with radii r and R (RF Patent No. 2191329, class and 7 F24J 2/14, 20.02.2001).

The installation has a higher concentration of radiation in comparison with analog. The disadvantage of a solar installation is the low value of the aperture angle within which the solar module concentrates direct and diffuse solar radiation.

The proposed invention solves follow what their technical objectives: increase the concentration of radiation on the radiation receiver, the aperture angle of the hub and the fill factor and use the useful area of installation.
