FIELD: heating systems. ^ SUBSTANCE: invention refers to solar energy engineering, and namely to agricultural industry, and is used for supplying electric energy and heat to agricultural and other consumers located at a long distance from centralised power supplies, and heat and fuel supplies. Combined solar plant intended for producing electric energy and heat is made in the form of a cascade of hollow hemispherical concentrators fixed on a hollow axle, at that diameters of concentrators from lower to upper one make smaller along the axle height, and distance between them is chosen so that solar radiation of lower concentrator completely come to lower surface of the next upper concentrator, at that surface of concentrators has a beam-reflecting surface, and concentrators have cavities between upper reflecting surface and lower surface whereon there fixed are solar cells producing electric energy. At that hollow axle and hollow concentrators are filled in with liquid which takes heat from concentrators and hollow reservoir located in upper part of the plant, and is accumulated in the capacity so that the heat can be distributed to consumers. ^ EFFECT: improving the degree of radiation concentration, and reducing active areas. ^ 2 dwg |
