To provide a sunlight collecting system suppressing production cost low, facilitating recovery work when a failure occurs, and achieving suppression of power generation cost by a receiver 2 immediately recovering a heat medium circulating inside in an emergency.
The receiver 2 is formed by the stereoscopic combination of a plurality of modules 20. At least a part of the modules is a trapezoidal module 20B. The trapezoidal module has an upper header 21B, a lower header 22B shorter than the upper header, and a plurality of heat receiving tubes 23 for connecting two headers. The heat receiving tubes are so formed that a cross-sectional shape is gradually changed into a wedged shape narrowed downward from above in a front view X and a wedge shape thickened downward from above in a side view Y.
