Applications
Photovoltaic power station tracking includes flat single-axis
linkage, oblique single-axis linkage, oblique single-axis, and
two-axis tracking system.
1. Flat single axis linkage
Suitable for latitudes below 30 degrees and ground slopes less than
12 degrees.
2. Oblique single axis linkage
Suitable for medium to high latitudes, the ground needs to be
approximately flat.
3. Oblique single-axis unit
Suitable for medium to high latitudes.
4. Dual axis
Suitable for any latitudes.
