As shown in Figure 1, suppose the present sun directly over sensing system, four light sensing components 101～104 receive the light of same intensity; When the sun when move on the left side, light sensing component 101 is covered by the shade of limit wall 120 gradually, a little less than light sensing component 101 received light intensities with respect to light sensing component 103 are, these signals are passed to after the control module, just can drive stepping motor, solar tracking system is turned to certain direction, thereby can reach the effect of following the tracks of the sun and make photovoltaic element 108 can maintain stronger irradiate light relatively always.
The shortcoming of above-mentioned traditional solar tracking system is when position of sun is offset left, the sensor light intensity of light sensing component 101 weakens, because, light R1 among the figure is covered by wall, so that light sensing component 101 receives more weak light intensity, yet light R2 exposes to wall, and the spuious light that has reflection shines light sensing component 101, and makes the light detection sensitivity of light sensing component 101 reduce.
