Provided is a solar light concentrating system which realizes suppression of power generation costs by applying a receiverthat is capable of suppressing a manufacturing cost to a low level, facilitating recovery work when a failure occurs, and quickly recovering a heating medium circulating inside in case of an emergency. The receiveris formed by three-dimensionally combining multiple modules. At least a part of the modules is a trapezoid-shaped moduleB. The trapezoid-shaped module includes an upper headerB, a lower headerB being shorter than the upper header, and multiple heat receiving tubeswhich connect the two headers. The heat receiving tubes are formed by successively altering their cross-sectional shapes in away that makes each heat receiving tube shaped like a wedge that becomes narrower from its top toward its bottom in a front view, and like a wedge that becomes wider from its top toward its bottom in a side view.

Solar light condensing system

A sunlight collecting system and a solar energy utilization system which collects sunlight with the sunlight collecting system are provided, a sunlight collecting system including a solar heat collector which includes a heat collecting element which is formed by a helically wound heat exchange medium circulation pipe inside which the heat exchange medium flows, in such a way to have an incurved light receiving surface which narrows and converges towards the sunlight inlet and a sunlight collecting reflector which includes a reflector group which includes a plurality of reflector segments each of which includes a reflecting surface which makes sunlight converge on a heat collector, a sunlight collecting system in which a plurality of heliostats Bm are arranged in places which are irradiated by the sunlight between a plurality of heliostats An, in which each of the heliostats An and the heliostats Bm reflect light in a direction to a light collecting point of a heliostat group in which the heliostat is included.
