Solar heat collecting apparatus and solar power generation system

A solar power generation system comprising:

• a solar heat collecting apparatus comprising
• a first heat exchanging unit including a first pipe through which a heat medium flows and a first heat receiving face which receives heat of sunlight reflected by a plurality of reflecting units, the first heat exchanging unit heating the heat medium flowing through the first pipe by using heat of the first heat receiving face, and
• a second heat exchanging unit including a second pipe through which the heat medium heated by the first heat exchanging unit flows, a second heat receiving face which receives heat of the sunlight reflected by a plurality of reflecting units, and a nozzle provided to the second pipe to discharge the heat medium flowing through the second pipe toward a back face of the second heat receiving face;
• and
• a power generation unit including a heat exchanger for carrying out heat exchange between the heat medium heated by the solar heat collecting apparatus and water to generate steam, a turbine to be driven for rotation by the steam, a power generator connected to a turbine shaft of the turbine, and a condenser for condensing the steam discharged from the turbine.
