APPARATUS FOR TRACKING SUNLIGHT, SUNLIGHT TRACKING METHOD, AND UNIT FOR DETECTING SOLAR HEAT

摘要

One aspect of the present invention relates to an apparatus for tracking sunlight so as to be capable of improving the efficiency of sunlight use by tracking the position of the sun. The apparatus for tracking sunlight according to one embodiment of the present invention is characterized in that it comprises: a rotation-driving unit for driving the rotation of an object having a panel; and a unit for detecting solar heat for using a thermoelectric current generated by a temperature difference between a sunny spot and a shady spot, which are formed according to the altitude and bearing of the sun, and then selectively driving the rotation-driving unit so that a panel normal line of the object becomes parallel to a line of sunlight.
