Abstract: The invention concerns to sphere of helio-energy producing connected with transformation the energy of solar rays to thermal energy. 
     The offered way of thermo-transformation of a solar energy is based on increase of thermo-insulation characteristics and simultaneously transparency of a surface closed helio-absorbent chamber in which carry out concentration of flows of solar rays, their transformation to thermal energy at the temperature considerably exceeding in set variants a boiling point of water, and accumulation of thermal energy with the raised temperature potential, in particular, not less than 150 degrees of Celsius. 
     Realization of a way carries out by means of consecutive connection of concentrators of solar rays. One of them carries out by creation of system of the local concentrators which have been built-in in a thermo-insulating lightproof material, covering the helio-absorbent chamber. The built-in concentrators and conductors of solar rays represent, mainly, the hollow truncated pyramids extended at length which sides are covered by a ray-reflecting material, and the bases are closed by a transparent thermo-insulating material. Thus the big bases of these pyramids - optical paths are located on an external surface of helio-absorbent chamber and as transparent rectangulars are located by the parties, practically, closely to each other, and the smaller bases are placed above her helio-thermo-transforming surfaces and have the smaller area of cross-section, than the external bases. 
     The second concentrator of solar rays is external. Such concentrators have, roughly, the form of the truncated pyramids which sides also are executed with application of a ray-reflecting material, and they are fixed by the smaller bases - inlet apertures near to an irradiated external surface of helio-absorbent chamber while they are inverted by the big bases - outlet apertures towards to the solar rays acting from surrounding space. In addition to this, the third level of solar ray rating of helio-absorbent chamber is created due to creation in surrounding space, on various distances from last, a field external ray-reflecting surfaces from which the reflected solar rays go to entrance apertures of external concentrators of solar rays in pyramid forms, creating additional rating in it of ray energy. 
     Configurations of accommodation helio-absorbent (helio-thermo-transforming) and thermo-accumulating materials are resulted as applied for volumetric chambers. The last can be carried out as well flat, including the small thickness, placed in horizontal, vertical or inclined positions. In this case the helio-absorbent chamber incorporates heat-conducting thermo-insulated channels with separately stated thermo-accumulating constructions, and as heat-carriers gaseous or liquid environments are applied. 
     The offered way of thermo-transformation of a solar energy, allowing to carry out multicascade rating a solar energy in the helio-absorbent chamber and to create its rather high thermo-insulation solves a problem of priority creation high-economic and non-polluting helio-boilers, helio-thermo power plants and household, including mobile, helio-energy installations which technical and economic recoupment does not exceed 3 years.
