PURPOSE: An actinography device and a method thereof for inspecting the reliability of a solar cell, and a device and a method for inspecting the reliability of the solar cell are provided to measure solar radiation on the solar cell, thereby measuring the solar radiation stably and reliably. CONSTITUTION: An actinography device for inspecting the reliability of a solar cell comprises a first solar cell(110), a second solar cell(120), temperature sensors(130, 140), a cooling element(150), and a controller(180). The first solar cell generates electricity by receiving radiation greater than a predetermined level. The second solar cell generates electricity by receiving radiation greater than a predetermined level. The temperature sensors measure the temperature of the second solar cell. The cooling element cools the first solar cell. The controller measures radiation applied to the first solar cell, and controls the cooling element to prevent the temperature of the first solar cell from increasing over the predetermined temperature by the temperature measured by the second solar cell using the temperature sensors.
