SDE Dual Axis Solar Slew Drive With Planetary Reducers, Long Life For Solar Trackers
Dual Axis Slewing Drive Description
SDE7 7 inch dual axis slew drive are perfect for situations which need track towards the sun all the time from sunrise to sunset. It can increase the energy production capacity. Typical applications include dual axis solar trackers, it can also applied in satellite and radar dishes, machines which need moving 360 degrees at both directions.

Type Of Slew Drive Solar Tracking System
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
