Dual-Axis Solar Tracking Units (DAT)

:: Dual Axis Tracking::  (see How to install a DAT unit)

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 images)

If you have an area from 2mt to 8mt clear ground that provides Dawn till Dusk hours of Sunlight, then we highly recommend you install a DAT-4 or a DAT-8 unit, that will Harvest between 25kWh/45kWh/p per day respectively.   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 the south of Tasmania, this is done by follow the sun completely, relevant to your global location.  The increase in energy captured by solar dual-axis tracking 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 (directly at) to 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, Dual-axis trackers are more complex to install (see 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 roof-top system, due to the obscure angle of the sun striking Roof-top panels for 2/3 of the 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 is the worst of all Solar harvesting options, and uses approx. double the Solar Panels to harvest the same Energy as a DAT unit.

So, for Residential customers with a sunny area, we recommend you purchase a DAT-4 or DAT-8 Solar Tracking unit(s), and if required these units can easily be relocated, if install with a Spider Foundation and Earth Ground Screws!

Our DAT units come purposely over-engineered, each with 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).

So, you can now choose a residential DAT Kit that can holds from 2~18 x 380W or 1~14 x 500W Solar Panels !

Our Fully Automatic DAT Kits all come with a choice of Mast Height, Slew Bearing, Tilt Chassis, Linear Actuator, waterproof pole mounted Stainless Steel Control Box housing, with Optional Foundation types, Wind speed indicator, and over rotation Stop kit.

Duel Axis Tracker studies shows how they can re-pay the initial micro grid investment cost in 3~8 years, depending on your 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 of the system.

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

So basically, batteries are the big game charger in the Energy market - as during the day all excess energy is sent to the batteries are charged have the choice to automatically export it straight into the State Grid for a feed-in tariff - This simple means that at sun set you will only be consuming your own energy from the Batteries until sun-rise, thus eliminate paying the retail price 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 6~11 cents/kWh Retailer feed-in tariff, as you simply remained enslaved to the electrical Retailers, by choosing to continue paying the retail price for power after sunset!

The purpose of Solar Trackers is to generate substantially more energy than a standard flat or fixed tilted Solar racking, as solar tracking greatly improves the energy harvested and leads quicker energy independence, and when you produce more energy than you consume &/or have Batteries storage (optional), this opens the opportunities to become a Peer-to Peer (P2P) energy trader, or look at installing a Reposit Box to possibly earn GridCredits.

Fitting a solar system without Batteries, only allows you to minimise your power bills, as commonly 50~80% of peoples solar energy is sold to the retailers for little return, many people that Batteries are the main Turn-key item to become truly Energy Independent, instead of reducing there energy bills or generating a small income.

The up-front cost for a solar tracker is higher, and without Batteries the payback period is longer.  In reality, spending more money on additional solar cells, yields higher generation with little financial return to the system without energy storage.

We only recommend purchasing a Hybrid inverter, and 370W or larger solar panels, as 270W solar panels harvest 30% less energy & more panels are required, creating a larger footprint to harvest the same energy!

Over size inverter & batteries are better to control your future energy production and distribution, hybrid-inverters are designed to handle multiple input voltage from several power sources, such as Solar, Wind, Aqua, Battery and even Generator input, may Hybrid inverters come with built in Auto Generator Start (AGS) & management, and automatically starts & stop a generator as programmed.
