Abstract
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.
