     SUBSTANCE: solar heat photoelectric module with the compound parabolic concentrator consisting of the paraboloidal concentrator "Focon" and the heat photoelectric receiver located in a focal plane with uniform distribution of the concentrated radiation, differing in that the solar heat photoelectric module contains the compound parabolic concentrator and the cylindrical heat photoelectric receiver with the cooling device installed in the focal plane area, the concentrator representing a rotation body with smooth internal reflection surface, consisting of several zones (a-b, b-c, c-d) is designed compound using the principle of collecting of the reflected beams in two focal plane areas from separate zones of the concentrator: - the form of the reflecting surface of the zones a-b, b-c of the concentrator X (Y) is determined by the system of equations corresponding to the condition of uniform illumination of a surface of photo-electric part of the heat photoelectric receiver designed in the cylinder shape from the commutated high-voltage FEP with the length h o  and the radius r o , Y n =R n   2 /4f o , X n =R n -(k-1)r o , R n =2f o (tgα n +cosα n ), Δα=α o /N, α n =Δα(n-N/2), X*=2f 1 Q[(1+1/Q 2 ) l / 2 -1], Q=B/r o , B=h o +h, Y*=X* 2 /4f 1 , Y* n =ΔY*n, X n =[4f 1 (Y*+Y* n )] 1 / 2 , ΔY=P[1±(1-4R/P 2 ) 1 / 2 ]/2, P=L+Y b , L=f o +h+h o /2, where α n  is an angle (in the zone of the working profile of the concentrator a-c) between the ordinate level in the point of coordinates X n , Y n  and the beam reflected from the parabola surface with the focal length f o  arriving to focal plane area with the width h o  located on the radius r 0  of the cylindrical photo-electric receiver in Δα=α o /N intervals where n is selected from a series of integers n=1, 2, 3…N, values of the parameters f o , f 1 , k are selected according to boundary conditions, and geometrical concentration of illumination of the photo-electric receiver K n  is equal in intervals of the concentrator radius ΔX n =X n -X n-1 : K n =(R n+1   2 -R n   2 )n/d o , - shape of the reflecting surface of the zone c-d of the concentrator X (Y) is determined by the system of equations corresponding to the condition of uniform illumination of the surface of thermal part of the heat photoelectric receiver designed in the form of the truncated cone with a lateral surface with the length d*, upper radius r ob  and the lower radius r b : X c =2Y c (1/codβ b -tgβ b ), tgβ b =(Y c -H b )(R c -r ob ), f b =Y c -X c tgβ b , r b =X c -R c , d*=h*/sinφ o , d* n =d*n/N, K n =(R 2   n+1 -R 2   n )/(r* n+1 +r* n )Δd*, X bn =2f b (tgγ bn +1/cosγ bn ), tgφ o =h*/(r o -r* bo ), where β b  - an angle (in the zone of the working profile of the concentrator c-d) between the ordinate level in the point of coordinates of X c , Y c , and the beam reflected from parabola surface with the focal length f b  arriving to focal plane area of the truncated cone with the radius r b  of the photo-electric receiver, γ n  - an angle (in the zone of the working profile of the concentrator c-d) between the ordinate level in the point of coordinates X n , Y n  and the beam reflected from the parabola surface with the focal length f b  arriving to the focal plane area of the truncated cone with the width d* of the photo-electric receiver in the intervals Δd*=d*/N, where n is selected from a series of integers n=1, 2, 3…N. The values of the parameters f b , k are selected according to boundary conditions, φ o  is an angle of inclination of the lateral surface of the truncated cone of the photo-electric receiver, and the geometrical concentration of illumination of the photo-electric K n  receiver is equal in intervals of the concentrator radius ΔX n =X n -X n-1 : Kn=(R=2n+1-R2n)/(r*n+1+r*n)Δd*.
