A solar energy module comprising: a frame having two opposing and substantially parallel sides (4b, 4d) and having two opposing and substantially parallel ends (4a, 4c) perpendicular to said sides, thus forming a rectangle; a plurality of rectangular-shaped reflectors each being a sandwich panel comprising two face sheets (91a, 91b) and an inner core, wherein said face sheets (91a, 91b) are adhesively bonded to said inner core on opposite sides, such that inner core keeps said face sheets (91a, 91b) apart to resist bending loads, wherein each reflector has an axle (9, 9 a, 9b, 9c, 9d) having a pair of axle ends such that each reflector is rotationally connected to the ends of said frame, at least one said axle ends of each said reflector having a motor to rotate each said reflector; wherein a reflector insert is embedded into the structure of reflector, wherein the exterior surface of said insert is bonded to the interior surface of a cavity in reflector having the same dimensions to assure that torque applied to insert is transmitted without failure to reflector, a pair of arms with each arm having an absorber end and a frame end with the frame end of each arm being rigidly attached to the ends of said frame; an absorber, attached between the absorber ends of said arms and positioned such that said absorber has an axis that is substantially parallel to the axis of rotation of said reflectors such that said absorber absorbs solar energy reflected from said reflectors; and an insert secured into a cavity in the frame end (4a, 4c); a motor assembly comprising a flexible coupling, said motor and a holder; wherein the exterior of the motor is bonded to the interior of the holder; and wherein the outer surface of the holder and the inner surface of the frame insert have the same shape and engage each other and are configured to prevent rotation between the motor assembly and the frame end (4a, 4c). a frame having two opposing and substantially parallel sides (4b, 4d) and having two opposing and substantially parallel ends (4a, 4c) perpendicular to said sides, thus forming a rectangle; a plurality of rectangular-shaped reflectors each being a sandwich panel comprising two face sheets (91a, 91b) and an inner core, wherein said face sheets (91a, 91b) are adhesively bonded to said inner core on opposite sides, such that inner core keeps said face sheets (91a, 91b) apart to resist bending loads, wherein each reflector has an axle (9, 9 a, 9b, 9c, 9d) having a pair of axle ends such that each reflector is rotationally connected to the ends of said frame, at least one said axle ends of each said reflector having a motor to rotate each said reflector; wherein a reflector insert is embedded into the structure of reflector, wherein the exterior surface of said insert is bonded to the interior surface of a cavity in reflector having the same dimensions to assure that torque applied to insert is transmitted without failure to reflector, a pair of arms with each arm having an absorber end and a frame end with the frame end of each arm being rigidly attached to the ends of said frame; an absorber, attached between the absorber ends of said arms and positioned such that said absorber has an axis that is substantially parallel to the axis of rotation of said reflectors such that said absorber absorbs solar energy reflected from said reflectors; and an insert secured into a cavity in the frame end (4a, 4c); a motor assembly comprising a flexible coupling, said motor and a holder; wherein the exterior of the motor is bonded to the interior of the holder; and wherein the outer surface of the holder and the inner surface of the frame insert have the same shape and engage each other and are configured to prevent rotation between the motor assembly and the frame end (4a, 4c).
