Residential Home Solar Arrays
We sell high quality 300W~500W solar panels/modules, the additional expense to purchase quality panels & DAT unit, is recovered in under 12 months with additional energy harvested by a DAT.
Dual Axis Solar Trackers are Superior at Energy Harvesting !

This sized Module supplies enough energy for large Residential & Semi-Commerecial energy consumption.
Wide Stand DAT-8 Module.
Our DAT units can be fitted with common 60cell, 72cell & 96cell Solar modules to match consumption.
As Australia is in a solar "hot zones", a single DAT-4 Unit fitted with 4x 500W Panels shown above, harvests 22kWh of solar energy per Day. That will cover the energy consumption of a premises with a energy bill of $350, &/or may harvest enough energy to cover the cost to pay the over inflated "service fee" to remain State Grid connected.
Please Note: People Renting/Leasing Apartments or Homes, may be interested in purchasing a unique and easily Transportable PV micro grid, especially configured for people who move around between homes & apartments, all without needing body corporate approval. If interested Click Here to read more.
How much does a Residential Solar Array cost ?
Firstly we recommend you Only purchase a Hybrid Inverters, as a Solar-only Inverters are not suitable if you later decide to purchase Battery storage, unless you also purchase additional Control Charger!
Solar panel can start from $200 depending on quantity purchased, Hybrid inverters start from $900.
It is simple to calculate a system to suit you energy consumption, so go get your energy bill.
We firstly recommend Installing a Dual-Axis Tracking (DAT) using a 24V heavy duty Double Slew Bearings or combination of a 24v single Slew bearing & 24v Linear actuator, as these require the least amount of maintenance.
- 440W (144cell) solar panels harvest approx. 35% more energy than older 60cell, 290W panels.
- 500W (96cell) solar panels harvest 85% more energy than 60cell, 290W panels.
- Both the above panels use a smaller mounting footprint to produce the same kWh energy & require less panels!
Harvesting examples using DAT units with a latitude 34° for Sydney;
Example-1: DAT-4 unit =4x 440W panels harvests 19kWh day, replaces $670 quarter power bill, using Batteries to self consume all harvested energy.
Example-2: DAT-8 unit =8x 440W panels harvests 38kWh day, replaces $1'100 quarter power bill, using Batteries to self consume all harvested energy.
Example-3: DAT-15 unit =15x 440W panels harvests 72kWh day, replaces $1'600 quarter power bill, using Batteries to self consume all harvested energy.
There are cheap Hobby DAT kits (shown here), these use cheap jumpy 12v motors, racking & tracking electronics, they cost approx. $600 each (excluding solar panel), you can purchase them on Amazon/ebay, good luck with them!
NB: When it comes to Solar There are also 400~490W BiFacial Solar Panels with a clear type backing, that harvest up to 20% additional energy from Reflective light, obviously these Panels cost more, they provide 40% increase over 270W panels, and these reduce the break-even Time-line quicker, the additional harvesting is ongoing for the next 25+ years!
The solar world is changing rapidly, so don't be fooled into purchasing 270W panels on the fancy TV adds, unless they confirm they will supply a Hybrid inverter and the installers are going to fit the panels facing North and installed Tilted to your Latitude (Sydney 34°), be aware that the footprint of the 270W panel array may not fit on your roof, if not you will be the one loose long term, largely due to Fixed flat panels and panels not installed to the optimum angle will harvest SIGNIFACANTLY less energy!
That is why we only offer DAT (we are currently designing residential roof-top SAT), as both DAT & SAT are simply the best at harvesting solar energy, if you live in Town & looking to install DAT you may need ask what the local council requirements are, this changes from state to state.
If you already have a Solar array that's paid-off, you are in the best situation, as it only takes 1~2 years to pay for the correct sized battery bank based on energy consumption, batteries provide greater return in self consumption, and paid off in electricity savings very quickly, that's why we strongly advise you invest in a battery bank - Any energy not consumed by your premises during the day is sent to your batteries & once charged, excess energy can then be exported into the state grid, where the a measly feed-in rebate may cover the Electricity Retailer "Supply Charges", then the grid is only used to black-out proof your premises.
NB: If you plan to store your excess energy in batteries, it is critical you also invest in a New multi-input Hybrid Inverter - enabling other type of energy generation to be incorporated into a system at any time, standard solar inverters simply can't do that!
Home Grid Pay-back time is discussed here in more detail, and will give you a good understanding of the potential payback period.
Dual-axis trackers capture the full extent of the sun, but are more complex and hence more expensive, DAT make more of a difference at greater latitudes (more southerly in Australia) where there is substantial seasonal variation in the sun’s height and arc in the sky.
As a guideline to different installation of 8x 440W solar panels (3.5kWh) will generate the following;
- Fixed Flat panes (No Tilt) Harvests 15kWh day peak.
- Fixed Tilted panes @34° Tilt Harvests 20kWh day peak.
- Single-axis Tracking Harvests 30kWh day peak.
- Dual Axis Tracking Harvests 40kWh day peak.
Note that Flat-panel installations are only able to harvest Peak energy for approx. 3 hours per day depending on the time of the year and location from the equator, where Single-axis tracking is more efficient, and Dual-axis tracking (DAT) will harvest energy over 10hr per day, the further south you are located the better.
A Micro Power Grid with Batteries and Two Axis Tracking can re-pay the initial investment cost in 4~6 years, then the system owned will have an ongoing income for well over 20 years, obviously Batteries are the key part of the system !
We recommend you invest in a multi input Hybrid inverter, it will only cost additional few hundred dollars but will let you control every aspect of your energy production and distribution, these smart hybrid-inverters are designed to handle multi input voltage from several energy sources, such as Solar, Wind, Aqua, Battery and even Generator input, ours also comes with built in Battery charge management that can be programmed to automatic start or shut-down as required !
Old Solar Rebate:
In November 2016 the $0.40~$0.60 per kWh Solar feed-in Tariff ended in Australia, hopefully your Solar array has already paid for itself in reduced energy costs and feed-in Tariff/Rebate.
Now, the quickest way to become energy independent, is to purchase Dual-axis Solar Array and Battery bank to store your energy, that in turn allows you to harvest & stored your energy after hours. If you don't have a battery bank, you are on the loosing end of the deceptive Electricity Retailer charges, as after hours you are forced to pay over 400% more than the current (2017) 8c kWh feed-in Tariff form the so called electricity Retailers, for energy you use after sunset, a point most people simply don't understand!
The reason most people purchase a larger than needed solar array, was to produce enough kW energy at the current $0.11 feed-in Tariff to offset/lower their energy bills. If you already have solar panels, it's a far smarter investment to purchase Batteries, you can calculate the saving/income here in under 2~3 years by purchasing just Batteries !
Investing in a battery bank cost from $200~$2500 depending on the technology. It is a lot smarter to harvest energy from your batteries to save you paying 27cents kWh, than export your solar energy to the Retailers @$0.08 cents kWh!
It's also worthwhile checking if there are any state or even local government Rebates available for purchasing solar panels or a battery storage system. For example, Adelaide City Council were providing Rebates of up to $5,000 for customers installing solar panels or a battery storage system.
