The plant has reflectors reflecting sunlight from a highly supported receiver (20), which comprises a receiver tube overlapped by a receiver cover. A measuring robot (30) is arranged on the receiver cover for measuring spectral intensity distribution of the sunlight at a region of the receiver tube. The measuring robot is displaced in a longitudinal direction of the receiver cover by a carriage (34). A measuring arm (31) is attached to the measuring robot, and comprises photoelectric cells for local release of the spectral intensity distribution. |
