FIELD: solar power engineering; solar power and heating plants. SUBSTANCE: module has cylindrical solar concentrator built of set of planar mirror facets mounted on bearing structure and linear photoelectric receiver disposed on focal line of mentioned concentrator; additional cylindrical concentrator installed on rear side of main one mounts heat absorber on its focal line; reflecting coat of main-concentrator planar facets is of selective type depending on spectral sensitivity of linear photoelectric receiver; additional cylindrical concentrator is, essentially, set of planar facets installed on parabolic-cylindrical bearing structure perpendicular to element of parabolic cylinder surface; convex side of parabolic-cylindrical structure is facing main cylindrical concentrator. EFFECT: enhanced efficiency of solar energy conversion due to reduced heating of receiver. 2 cl, 2 dwg
