Applications
1) Optimal inclination fixed
At low latitudes, the increase in electricity generation is minimal
due to the lower optimal inclination (as in 8°, almost no
increase); At high latitudes, the optimum inclination is large and
the amount of electricity generated is significantly higher (for
example, by about 25% at 50°)
2) Flat single axis
It track the change of incident angle within a day of the sun, and
its rate of increase in electricity generation at low latitudes is
significantly better than that of high latitudes. It is generally
believed that flat single axis tracking is more suitable for the
use of the latitudes less than 30 °.
3) Oblique single axis
It is more suitable for high latitudes.
4) dual axis tracking
This approach is clearly the highest in the increase in electricity
generation due to the tracking of changes in the incident angle of
the sun within a day and within a year.
5) Fixed adjustable
This type is based on the change of the angle of incidence within a
year of the sun to adjust the inclination of the bracket, thus
achieving an increase in power generation
The most fundamental difference between the different mounting
methods is the difference in the power generation they bring. Of
course, there will be differences in initial investment and
operational maintenance costs.
Planetary reducers are ideal for applications requiring high torque
in a small package and an output shaft with coaxial alignment
