SOLAR MODULE WITH CONCENTRATOR (ALTERNATIVES) Russian patent published in 2003 - IPC

FIELD: solar engineering. SUBSTANCE: solar module in which solar radiation is collected by compound cylindrical parabolic concentrator made of two parabolic cylinders has linearly focusing cylindrical parabolic specular reflector and receiver in the form of strip installed in parallel with focal plane of reflector; specular reflector is made in the form of one arm of cylindrical parabolic reflector with aperture angle below 48 deg. and is provided with semi-cylindrical specular reflector whose arm edges coincide with focal axis and with arm of main cylindrical parabolic specular reflector; optical axis of second specular reflector is parallel to focal axis of main reflector and is disposed in the midway between focal axis and arm of main specular reflector; third semi-cylindrical specular reflector is installed between axis and arm of second specular reflector, its edges being in alignment with axis and arm of second specular reflector. EFFECT: enhanced concentration coefficient and solar energy utilization efficiency, reduced cost of generated heat and power. 24 cl, 8 dwg
