PROBLEM TO BE SOLVED: To provide a solar heat collection system capable of restricting a reduction of an amount of attained energy by the solar heat collection system through variation of an amount of collected heat at a solar energy collector.SOLUTION: According to one embodiment of this invention, a solar heat collection system includes a heat collector unit for heating heat medium with solar light, a heater device for heating the heat utilizing fluid with heat of the heat medium and a heat medium flow passage for circulating the heat medium between the heat collector unit and the heating device. Further, the system includes a control part for controlling flow of the heat medium at the heat collector unit on the basis of an amount of insolation of the solar light or on the basis of a temperature difference between a first temperature of the heat medium at a first location and a second temperature of the heat medium at a second location at a more downstream side in regard to the heat medium than that of the first location.SELECTED DRAWING: Figure 1 |
