Abstract: FIELD: heating. 
     SUBSTANCE: invention relates to the field of solar engineering, in particular, to solar modules with concentrators for the generation of electric and heat energy. In a solar module with a concentrator comprising transparent focusing prisms with triangular cross section, with beam entry angle β 0  and total internal reflection angle        α   =   arcsin     1   n     ,         
 where n stands for the refraction coefficient of the prism having an entry face and a radiation re-reflection face forming a common dihedral angle φ, a face of concentrated radiation output with a radiation detector and a reflection device in the form of a mirror reflector which together with the re-reflection face forms an acute dihedral angle ψ being placed unidirectionally with the acute dihedral angle φ of the focusing prism. The concentrator is made from two symmetrical transparent focusing prisms having a common line of contact of the entry and output faces which is oriented in the North-South direction. The reflection device consists of a set of mirror reflectors with the length L 0  with equal acute angles ψ installed at some distance from one another, with a device for turning in respect to the re-reflection face, the entry face surface is fitted by additional mirror reflectors inclined to the entry face surface at the angle of 90°-δ and made in the form of louver with a device for turning in respect to the entry face surface, angle of the additional mirror reflectors' inclination to the entry face surface is directed differently from the acute angle φ of the focusing prism, axes of the turning device for the additional mirror reflector on the entry face surface and axes of the turning device for the mirror reflector on the re-reflection device with the re-reflection face are in one plane perpendicular to the entry surface, and the angles φ, ψ, δ, β 0  and α are interconnected by certain ratios. Method of manufacturing the solar module with the concentrator involves manufacturing of the focusing prism from optically transparent material, installation of the radiation detector, radiation re-reflection device with mirror reflectors and additional mirror reflectors on the working surface with turning devices. According to the invention cavity walls of two focusing prisms with an acute dihedral angle at vertex 2-15° are produced from hardened sheet glass or other transparent sheet material and are pressurised, the focusing prisms are installed so that the faces of entry and output of each prism at vertex have a common contact line oriented in the North-South direction, and afterwards the obtained cavity is filled by optically transparent medium, the radiation detector is mounted hermetically and the additional mirror reflectors with the turning devices are assembled on the working surface of the focusing prism as well as the turning device for the radiation re-reflection device. 
     EFFECT: invention is to increase optical efficiency factor due to reduced losses of radiation in a module and increased coefficient of solar radiation concentration.
