Dual Axis Solar Tracking Units (DAT)

:: Dual Axis Tracking ::

We are one of the very few businesses offering Residential sized Dual-axis Solar Trackers, and larger units commonly more suited for Solar Farms or Rural installations ! (see below equipment)

How to Install a DAT: Solar Tracking Unit.

We commonly just supply the main Plant & Equipment (DAT & Solar Panels), as 95% of customers undertake the full installation of our DATs, as they are on Rural Properties.   Digging the Foundation hole & Conduit Trench for the Wiring, would be the most difficult part of the project, leaving the Assembly of the DAT & fitting Solar Panels until last.

Why purchase a massive Roof-Top solar system that uses approx. three times as many solar Panels, and roof-top systems are more difficult & dangerous to clean & maintain.

Dual Axis-solar Trackers are Superior at Generating Energy !

There are Two main types of DAT Racking:

  1. Vertical Pole-n-Beam DAT Racking is the most used solar racking (as above).
  2. Horizontal Beam DAT Racking. (commonly installed close to the ground or optional Higher Vertical Poles, allowing the Ground to be used below the Racking)

Each DAT Racking type have different engineering, Pole & Tilt Axis configuration that can be changed to suit each project.

The smallest vertical DAT unit under development is a Bespoke DAT-1 unit, that only requires a 130cm wide rotational area that provides dawn-to-dusk Sunlight, when the DAT-1 is fitted with 1x 500W Panels, it Generates/Harvests 9kWh/p energy per Day in the Sydney Region.

The standard Rural DAT's we recommend you install are DAT-4 or DAT-8 units, these will Harvest between 22kWh/44kWh/p energy per day respectively if fitted with 500W solar panels, that would cover over 90% of Residential consumers, and small businesses in Australia.

DAT trackers capture the full extent of the sun's ray's, the further South of the Equator you live the better, up to 14 hours per day in south Tasmania, this is done by follow the sun completely, relevant to your global location.  The increase in energy captured by dual-axis solar trackers is increased by up to & more than 100%, than fixed flat mounted panels, as two-axis of rotation allow the tracker to position the solar modules/panels to face perpendicular to (directly at) the sun from dawn to dusk.

The Tracking Software adjusts for the sun’s height (latitude) as well as east to west rotation (sunrise to sunset), and automatically adjusts for seasons and faces the sun as it sits low in the horizon at sunrise and sunset, and obviously high in the sky in the middle of the day.

Yes, Installing a Dual-axis solar tracker is more complex (read instructions) and more expensive, however, the big pay-off is they Greatly increase the Solar energy harvested buy over 50%*, and only need 1/3 of the panels required of a flat roof-top system, due to the obscure angle of the sun striking Roof-top panels for 4~5 hours per day.

However, all Solar energy harvested is good for the environment, the Racking design choice is up to you, Fixed Flat & Tilted Rooftop or Ground mounted Racking are the worst at harvesting Solar energy, and can uses over double the Solar Panels to harvest the same Energy as a DAT unit.

So, for Residential urban/town customers with a sunny area, we recommend you purchase DAT-4 or DAT-8 Solar Tracking unit(s), and if required DAT units can easily be relocated, if install with a Spider Foundation and Earth Ground Screws, or you simple leave the Foundation behind & relocate the rest!

Our DAT units come purposely over-engineered, each with two 24V motors, east~west tracking via a Single-axis Slew Bearing, with north~south Tracking is done via a heavy duty Linear Actuator (screw jack).  You can now choose a residential DAT Kit that hold from 2~15 x 72cell 435W or 1~12 500W Solar Panels if you have the room!

In 2020 our Fully Automatic DAT Kits now come with a choice of Mast Height for increased ground clearance, all come with Slew Bearing, Linear Actuator, Weatherproof pole mounted Stainless Steel Control Box-n-housing, GPS, Wind speed sensor, and over rotation Stop kit are now standard, the purchase of a Foundation is Optional.

Dual Axis Tracker studies shows how they can re-pay the initial micro grid investment cost in 3~8 years, depending on the system, all done by replacing the power you purchase from the deceptively named Energy Retailers, by self consuming energy/power you produce, and then the system owner will no longer have an ongoing power bill for the next 30+ years, obviously a Battery is the turn-key part to becoming energy independent!

What's great about a Battery system: Batteries simply allows you to first & foremost store any excess energy you harvest or produce for later consumption, by commonly drawing energy directly from your batteries at sunset or extended bad weather.

Batteries are the big game charger in the Energy market - as during the day all excess energy is first sent to your batteries then once charged, you have the choice to automatically export your unused energy straight into the State Grid for a feed-in tariff - This simple means that at Sun set you will be consuming your own energy from your Batteries until sun-rise, thus eliminate paying the retailer for power after sun set & during the day - That is how you become energy independent !

Performance of Fixed Flat Panels v Solar Trackers in Australia

Again, solar trackers increases the performance of solar PV panels in the shoulder periods of the day, where a static fixed mount panel would only receive obscured sun exposure. This can be seen in the graphs of side by side solar tracking panels & static fixed panels.

NB: Solar Arrays without Battery storage, will provide little return on investment using the 10 cents kWh Retailer feed-in tariff, as you will simply remained enslaved to the paying the full retail price for energy after sunset!

Remember, the purpose of Solar Trackers is to generate substantially more energy than standard flat or fixed tilted solar Racking, as solar tracking greatly improves the energy harvested and leads quicker energy independence, if you produce more energy than you consume & have Energy storage, it opens the opportunities to become a Peer-to Peer (P2P) energy Trader.
