<p>A solar tracker is provided, comprising a supporting unit(14) holding a solar panel(903,1503), a driving unit(13) regulating the position of the supporting unit, an image sensor(10) having incident angle sensitivity characteristic, an identification unit(l l) identifying the current incident angle of the sunlight according to the signal output by the image sensor(10), and a control unit(12) controlling the driving unit(13) to regulate the position of the supporting unit(14) to make the sunlight vertically incident upon the solar panel(903,1503) according to the current incident angle. The micro lens(813) of each pixel in the image sensor(10) only refracts incident light with a certain specific angle to vertically incident upon the photodiode below the micro lens(813).</p> |
