PURPOSE: An analog device for detecting the sunlight position is provided to enable the position of the sun to be accurately measured since a two-axis actuator is controlled using the difference of the voltages, which are generated in solar cells of all directions of a dust collecting panel of the solar cell according to the incident angle of the sunlight. CONSTITUTION: For an analog device for detecting the sunlight position, a device for converting the voltage to an analog signal is installed, wherein the voltage is generated from solar cells A~D of a dust collecting panel(201) according to the incident amount on the normal direction of the sunlight. A microcontroller(300) calculates the incident angle of the sun to the dust collecting panel using the analog signals(303~306) of A to D. The motor driving part of a sunlight position tracking unit is controlled based on the calculated result from the microcontroller. |
