PROBLEM TO BE SOLVED: To provide a solar heat collection system capable of further improving solar heat collection efficiency.SOLUTION: A first pump increases a pressure of a heat medium, and a solar heat collector heats the pressure-increased heat medium with solar heat collected by a trough reflector. A first reducing valve reduces the pressure of the heated heat medium, and a second pump increases the pressure of the pressure-reduced heat medium and flows the heat medium into a heater. A second reducing valve reduces the pressure of the heat medium cooled by heat exchange implemented between the pressure-increased heat medium and a heating target fluid in the heater. The pressure-reduced heat medium flows and circulates in the first pump. The first pump, the heat collector, and the first reducing valve are installed on a rotary table. The reflector is driven to rotate to follow up a solar altitude. The rotary table is driven to rotate so that the reflector follows up a direction of the sun. For heat medium pipes in which the heat medium flows, an interface position between the heat medium pipe installed on the rotary table and the other heat medium pipes that are not installed on the rotary table is near a rotational axis of the rotary table. |
