Realize following the tracks of sunray with regard to solar panel 1 below and the process that returns is described:
One, tracing process:
As shown in Figure 3, when sunray (shown in solid arrow) casts oblique rays on to when following the tracks of electric power system 41, in other words now sunray does not have vertical irradiation on solar panel 1, due to blocking of shutter 413 pairs of sunrays, the area that the area ratio causing sunray to be radiated at solar panel B412 is radiated at solar panel A411 wants large, therefore the electric current that solar panel B412 produces is greater than the electric current that solar panel A411 produces, thus driver 421 operates, solar panel 1 is driven to rotate, until sunray is perpendicular to solar panel 1, now shutter 413 is owing to can not block the sunray exposing to solar panel A411 and solar panel B412, the electric current that solar panel A411 and solar panel B412 both sides produce is equal, drive unit 421 stops operating.
The lower period of the day from 11 a.m. to 1 p.m, sunshine casts oblique rays on, and light weakens, the electricity shortage of solar panel A411 and solar panel B412, and solar tracking system 4 is out of service.
Two, return course:
When within second day, the sun rises, as shown in Figure 3, be radiated at shown in sunray (dotted arrow) on solar tracking system 4, as shown in the process of above-mentioned tracking, solar tracking system 4 drives solar panel 1 reverse direction operation, makes sunray vertical irradiation on solar panel 1.
