A component (1, 7, 10, 13, 17, 21, 25, 29, 35) has a profiled front face (4, 8, 11, 16, 23, 26, 30, 41) and a rear face (5, 24, 34) and at least one fluid line (6, 9, 12, 14, 19, 27, 31, 38, 40). The component (1, 7, 10, 13, 17, 21, 25, 29, 35) is designed to allow a fluid present in the fluid line (6, 9, 12, 14, 19, 27, 31, 38, 40) to heat up when the front face (4, 8, 11, 16, 23, 26, 30, 41) is irradiated with sunlight.
