FIELD: construction.SUBSTANCE: in a roofing solar panel containing a housing with an inner cavity with a protective covering on the working surface, whereupon solar radiation strikes with a beam inlet angle of ?, and receivers consisting of switched solar cells, a compound concentrator is installed under the protective covering and made in the form of a diverting optic system transparent for radiation and consisting of a variety of prisms with acute angle ? between the beam inlet and outlet surface and several semi-parabolic cylinder mirror reflectors with parametric angle ?, which have beam inlet and outlet surfaces. Focal regions of all the reflectors are offset towards lower or upper side of the panel, and radiation receivers are installed parallel to the focal axis and perpendicular to the panel plane between the focal axis and the mirror coating of each reflector. Relation between beam inlet angle ?, acute angle ?, material refraction coefficient n of the diverting optic system and parametric angle ? of the semi-parabolic cylinder mirror reflector is given.EFFECT: reduction of panel material consumption.16 cl, 7 dwg, 1 tbl |
