The present invention comprises: a heat collecting device for generating high-temperature
superheated steam by concentrating
solar light in at least one assembled
concentrator while tracking the sun and by heating a heating medium supplied to a heat collector so as to heat the heat collector which is positioned at a predetermined distance from the
concentrator; a heat accumulating device for storing heat by heating a heat
storage tank for a floor heating method using the
superheated steam generated by the heat collecting device; a heat exchange device for carrying out heat exchange with the high-temperature and high-pressure saturated steam which is capable of driving a power generator by operating a
steam turbine using the heat stored in the heat accumulating device; and a heating medium water tank for supplying a low-temperature heating medium to the heat collecting device and the heat accumulating device, and storing the heating medium flowing through the heat exchange device. Thus, the present invention has high light concentrating efficiency by minimizing heat loss, can use
latent heat even at night or in the event of rain by storing heat in the heat
storage tank for a floor heating method, provides continuous power generation by operating a
steam turbine using saturated steam generated from the heat exchange with the
latent heat of the heat
storage tank, and can be used in various fields, such as
air conditioning and heating, culinary, and the like.
