1)      Both elevation and azimuth have slewing driver, not linear actuator for elevation 

2)      The max power output of  tracker can reach 20KW

3)      More steel is used, the weight of normal tracker (20panels) is about 900kgs or below, ours can reach 1300kgs, it will make the whole        tracker more wind resistant and stronger, wind loading is 42m/s

4)      The design is unique and simple, there are two kind of mounting: flat plate and double layer

5)      Light sensor control and time control together 

6)      Lower noise to avoid affecting resident

Tip-tilt dual axis tracker (TTDAT)

 

A tip-tilt dual axis tracker is so-named because the panel array is mounted on the tip of a long pole. Normally the east-west movement is driven by rotating the array around the top of the pole. On top of the rotating bearing is a T- or H-shaped mechanism that provides vertical rotation of the panels and provides the main mounting points for the array. The posts at either end of the primary axis of rotation of a tip–tilt dual axis tracker can be shared between trackers to lower installation costs.

 

Field layouts with tip-tilt dual axis trackers are very flexible. The simple geometry means that keeping the axes of rotation parallel to one another is all that is required for appropriately positioning the trackers with respect to one another. Normally the trackers would have to be positioned at fairly low density in order to avoid one tracker casting a shadow on others when the sun is low in the sky. Tip-tilt trackers can make up for this by tilting closer to horizontal to minimize up-sun shading and therefore maximize the total power being collected.

 

The axes of rotation of tip-tilt dual axis trackers are typically aligned either along a true north meridian or an east west line of latitude. It is possible to align them in any cardinal direction with advanced tracking algorithms.
