Dual Axis-solar Tracking Units (DAT's)

Why install Dual Axis-Solar Tracking ?

Simply because DAT Solar Racking is Superior at Generating Peak Energy than ANY other type of Solar Racking, and a DAT's also reduce the quantity of solar panels by approx. 50%, to generate the same energy per day, thus reducing the demand on Rare earth materials!

Yes, DAT Racking is more expensive, however the big Pay-off is a Quicker Return-On-Investment (ROI), by Generating Peak/Superior Energy each day, for the Next 25+ years.

Large Ground mounted DAT's are Not for everyone, unless you have an Area void of Shading, as that will provide Peak Energy Generation for 10 hours per day in Sydney, and the further South you live in Australia, Peak Generation can be for 12+ Hours per day!

There are Two Types of Sun TRACKING Control Modules;

  1. GPS Tracking comes standard with all DAT Unit, good until Sun is blocked by Cloud cover !
  2. Radiation Tracking rotates the Solar Racking to point too the Brightest area of the Sky when the Sun is covered by Clouds!
    A Commercial DAT Radiation Control Module Upgrade is Made in Poland, and inc. a Light sensor Cost approx. $500, and is Plug & Play after installing a Light Sensor.
    This DAT RADIATION Control module inc. Light Sensor & Costs $200, but require new NC Stop sensors to be fitted & Wired.

See what is required to Install a DAT Solar Tracking Unit.

We are one of the few businesses offering small Residential sized DAT's up to larger commercial DAT's, commonly more suited for Solar Farms & Rural installations ! (see below equipment)

We predominantly supply Off-Grid Systems installed behind the Meter with Hybrid Inverters, 95% of our customers are on Rural Properties & most undertake the full installation themselves.

The installation of a DAT consists of the Digging the Foundation hole & Trenching for Electrical Conduit to where the Inverter(s) and Batteries are to be installed. Digging the Trench & installing Conduit & DAT Foundation is considered the most time consuming part of the project, leaving the Assembly of the DAT units & fitting of Solar Panels, usually takes 5 hours to a day per unit for an inexperienced person.

Why purchase a massive Fixed Roof-Top solar that requires approx. 50% more Solar Panels, and don't forget the Fixed rooftop Panels can ONLY Generate Peak Energy for approx. 2.5 hours per Day, then the remainder of the Day will be generating Shoulder Energy.  Roof-top systems are more difficult & dangerous to Install, Clean & Maintain.

Pole mounted DAT's are able to be installed at Ground level, using our Hinged Mast design (currently in development), this will make the assembly of DAT's a lot easier, as No ladders & Scaffolding is needed.

Dual Axis-solar Trackers are Superior at Generating Energy than any other type of Racking!

There are Two main types of DAT RACKING:

  1. Vertical Pole-n-Beam DAT Racking is the most purchased solar racking type (as above).
  2. Horizontal Beam DAT Racking. Is commonly installed close to the ground or can be mounted onto Higher Vertical Poles, allowing the land below to be used for Agriculture.

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 5.5kWh/p energy per Day in the Sydney Region.

The standard Rural DAT's we recommend you install either a DAT-4 or DAT-8 units, these will Generate between 15kWh to 82kWh/p energy per day respectively if fitted with 700W 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 generated 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 generated 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 Generation Solar energy, and can uses over double the Solar Panels to Generate 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!

We Design our DAT units to be purposely over-engineered, all have 24V motors for east~west tracking via a Single Slew Bearing, with north~south (Tilt) Tracking is done via a heavy duty 24V Linear Actuator (screw jack).  You can now choose a residential DAT Kit that hold from 2~15 445W, 500W or 700W Solar Panels if you have the room!

In 2022 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 housing, GPS, Wind speed sensor (Anemometer), and Over Rotation Stop Sensors are now standard, the purchase of a Foundation is Optional, as there are several Foundation types to chose from.

Studies show Dual Axis Tracker often provide a Return-On-Investment (ROI) of 25% per year, & less depending on the system, all done by replacing the power you purchase from the deceptively named Energy Retailers, by self consuming all energy you Generate, 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 Totally energy independent!

What's great about a Battery system: Batteries simply allows you to first & foremost store any excess energy you generate, for later consumption as needed, commonly after Solar Sunset or during Bad weather, by simply drawing the energy directly from your batteries.

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 having to pay the Energy Retailer for power after sun set  or 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 Power 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 generated 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.
