Description
Dual axis Pole solar tracker :
1) Both elevation and azimuth have slewing
driver, not linear actuator for elevation
2) The max power output of tracker
can reach *0KW
3) More steel is used, the weight of
normal tracker (*0panels) is about **0kgs or below, ours can reach
***0kgs, it will make the whole tracker
more wind resistant and stronger, wind loading is *7m/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.
