By adjusting the angle and direction of the solar array, the automatic sun tracking system makes the solar array absorb the direct sunlight to the maximum extent.

Can be divided into two tracking systems,

1. Uniaxial: Set the main axis at a certain angle, and the solar cell array faces south. This kind of array has simple design and low power consumption, and can adjust the solar cell array from east to west.

2. The biaxial solar cell array can be adjusted not only in the east-west direction, but also in the north-south direction. This array design is more complicated, but solar cells also generate more electricity.

Hehe, I prefer the uniaxial one, because it is simple, low in self-loss and cheap.
