DART-8 Solar Tracking Unit

Dual Axis-solar Radiation Tracking (DART) Racking is superior at Generating Energy than all other Solar Racking types, all DART units can Generate Peak Energy from 10+ hours of Sunlight per Day, and the Further South of the Equator you live, the more Energy a DART unit you will generate!

Dual Axis Slew Drive.

This is our Design DART-8-VAWT Unit, it's an 8 Panel Dual Axis-solar Radiation Tracker that uses 2x Slew Bearings, Wind & Light Sensor, instead of the inefficient GPS Tracking.

This DART-8-VAWT Unit also offers the Option to install a 3kW Vertical Axis Wind Turbine (VAWT), that is mounted on a separate 300cm Double Flanged mast fitted above the Solar Racking.


DART-8 Generates the following Daily Energy;

  • 8x 700W panels = *56kWh/p Energy per Day.
  • 8x 500W panels = *40kWh/p Energy per Day.
  • 8x 445W panels = *36kWh/p Energy per Day.

* /p stands for "Peak Energy", in other words the Solar Panels are exposed to Full Sunlight all day.

A DART-8 Unit Generates enough energy per day to make a large Residential or Semi-Commerecial business energy independent, when incorporated with the correct sized Energy Storage.

NB: The further South or North of the Equator you live, all DART units will Generate more energy, due to the Arch of the Sun through the Sky.

The Rotation of a DART Racking.

For those looking to Dig or Auger a minimum 40cm Diameter Foundation Hole for a Double Flanged Foundation Pole, you should allow an additional depth of 30cm, to provide a 30cm Cement Bed below the bottom Flange Plate to take the vertical load of the DART.

It is advisable to install a Earth/Ground spike at the same time, old school would be a Re-bar or Star Picket.

All you need to know to install a DART Array;

1. A standard DART does NOT include a Foundation!

As some customers prefer to manufacture there own foundation.

However, A standard Double Flanged Foundation Pole for a DART-8 is 130cm.

There are another 3 Foundation types to chose from, based on the Ground type!

2. What is the Solar Panel Ground Clearance height in the morning & evening ?

A DART-8 installed with a standard 90cm Main Mast, with the Racking Tilted 60 degrees, the panels will be approx. 300mm (30cm) above the ground, a 130cm Main Mast provides 70cm Clearance.

If you want to increase the ground clearance the Main Mast heigh needs to be increased, allow approx. $1.25 per cm increase.

3. What is the Ground spacing require between multiple DART's to stop panel shading?

North-south direction spacing is approx. 8 meters.

East-west direction the distance is approx. 9 meters.

These distances will change depending on your Latitude location & any Shading from Trees/Terrain.

4.What height are the Panels in the Tilt & Stow Position?

In a Tilt position of 60° the panels will be approx. 600mm (60cm) from the ground.

In the Stow position (Horizontal) with a standard Mast, the height will be approx. 250cm Heigh.

5. The location & Height of a DART units will be set by the Surrounding Trees, Buildings &/or Terrain, as DART's should/need be installed in an area that capture the most Sun.

Australian INSTALLERS: Make sure that in Winter any Trees growing on the North side of any DART's location, does Not Cast a Shadow over the Solar Panels, as it will simply reduce the Daily Energy Generated.

the height of the tree.

Below information is required, before we manufacture a DART unit to your Specification;

1. You tell the exact height from the ground (at a 60 degree tilt)

2. Tell us how many units are needed (according to North-south direction and east-west direction).
