FIELD: power engineering. SUBSTANCE: device has glass tube having antireflection coating and photoelectric receiver for producing hot water or heating. Internal diameter of cylindrical solar radiation receiver is equal to cross width of photoelectric receiver double- glass pane to enable to control its position about the longitudinal axis. Cylindrical receiver side coincides with circular cylindrical reflector. The opposite edge coincides with the second semicylindrical reflector axis and focal axis of the parabolic cylinder reflector. Another embodiment has hollow blackened cylindrical metal receiver of solar radiation having liquid heat carrier circulating in longitudinal zigzag canals in receiver casing. Air circulates in the inside of cylindrical receiver by means of fan. EFFECT: increased concentration coefficient; enhanced effectiveness of solar radiation power utilization; low cost. 4 cl, 2 dwg
