Abstract
In this paper, the solar sensing device used to measure the solar radiation whether it is same in all directions or maximum in the particular direction to convert it into the more electricity. The solar servo control tracking device using a pyranometer is disclosed. The device includes: a solar panel; a tracker having a solar panel driving motor driving the solar panel; a tracker controller controlling the tracker; first pyranometers measuring a solar azimuth in EW and detecting solar radiation of 380 nm to 840 nm wavelengths; second pyranometers measuring a solar azimuth in NS and detecting solar radiation; and a third pyranometer measuring a solar azimuth in the CE and detecting solar radiation. The tracker controller includes: signal amplifiers amplifying detection signals in three azimuths by the pyranometers; signal processors filtering the amplified detection signals by limiting a voltage; and a main control microcomputer outputting a control signal to the solar panel driving motor to stop the solar panel when the solar radiations are same and the solar radiations in one direction are maximum.
