Flat single-axis tracking bracket refers to the bracket tracking the rotation of the sun around a horizontal axis. This horizontal axis can be north-south direction or east-west direction, when north-south direction The power generation is high, so the axis of the flat single-axis tracking bracket is generally in the north-south direction.

An oblique single-axis tracking bracket is a bracket that rotates and tracks the sun around a north-south inclined axis. In the middle and high latitudes, compared with the flat single-axis tracking system, the power generation of the inclined single-axis tracking system has been greatly improved. Of course, since the rotation axis is in an inclined state, the cost of the inclined uniaxial tracking bracket is also higher than that of the flat uniaxial bracket. The azimuth single-axis tracking bracket can be regarded as a fixed bracket installed on a rotating base, as shown in Figure 9-20. When this bracket is tracking, the angle between the square array and the horizontal plane remains unchanged, but the azimuth angle of the square array changes.

The dual-axis tracking bracket can be regarded as a bracket whose inclination angle can be adjusted automatically installed on a rotating base, as shown in Figure 9-21. The so-called dual axis means that the bracket can rotate along two independent axes. Generally, one axis allows the azimuth angle of the bracket to rotate freely, and the other axis allows the inclination angle of the bracket to freely rotate. In this way, the dual-axis tracking bracket can always remain perpendicular to the sun's rays, which is the highest power generation of all tracking brackets.
