(S130) when the temperature of the fluid supplied to the solar collector (10) reaches the set temperature (S130), and storing the experimental performance data for the solar collector (10);
(S150) of supplying the fluid of the thermostat (70) to the solar collector (10) by controlling the pump (30)
And a step (S170) of testing the solar collector by the set target.

6. The method of claim 5,
The step S 130 of storing the experimental performance data for the solar collector 10,
The time of arrival of the fluid temperature of the thermostatic chamber 70, the flow rate of the fluid supplied to the solar collector 10 and the target temperature of the fluid flowing out of the solar collector 10 and the arrival time of the fluid in the thermostatic chamber 70 (CT_In: constant tank inlet) and the temperature
The temperature of the fluid flowing out of the constant temperature bath (70)
A temperature (HC_In: Heat Collector Inlet) of the fluid flowing into the solar collector 10,
(HC_Out: Heat Collector Outlet) flowing out from the solar collector 10,
The surface temperature (GS) of the collector (vacuum tube) of the solar collector 10,
The data of the header 12 of the solar collector 10 and the temperature of the outside of the solar collector 10 are summarized in the form of Excel data And the temperature of the solar collector is measured.
