7 Inch Solar Slew Drive Featured With Self-locking For Tilted Solar Tracking System
Solar Slew Drive Description
There are two principle types of trackers, single and duel axis trackers. Single axis trackers are adjusted every month or so account for seasonal changes in the suns position, the single axis is then used to track the daily movement from east to west of the sun across the sky. Duel axis trackers eliminate the need for monthly adjustment by using one axis to track the suns daily movement and another axis to track the seasonal movement. A single axis solar tracker improves solar output by around 25% and a dual axis tracker by around 40%.
A solar tracker is a mechanical device - automatic act to guide favorably with respect to the sun's rays from a photovoltaic panel, a solar thermal panel or a solar concentrator. The solar tracker causes an increase in the power of the captured solar energy and, therefore, the actual performance of the renewable energy device. One type of solar tracker is the heliostat.
The main objective of a tracker is to maximize the efficiency of the PV panels, mirrors which is mounted on the slewing drives.
In the photovoltaic field, PV modules mounted on a tracker are generally arranged in a row, array so that the slewing drive could drive not only one solar modules.
In the field of solar concentration, a solar tracker is useful to keep the fire point generated by the paraboloid or mirror constant in the channeling element of the liquid to be heated. The greater the perpendicular alignment with the sun's rays, the greater the efficiency of thermodynamic conversion and the thermal energy produced for the same surface.
That need a high precision of a slewing drive.
