Harvesting Solar Energy and energy storage.

Australia is one of the world’s solar “hot zones” which provides maximum exposure to the sun’s rays throughout the year, and this abundant energy source is FREE, solar panels capture this energy and convert it to usable power for your home or business.

IMPORTANT: The 'Tier 1' term used by may Retailers is deceptive & misleading to say the least, Tier rating has NOTHING to do with the solar panel Qulity or a guarantee panels are free from defects or will perform over the life of the system.

The Tier rating system was developed by Bloomberg New Energy Finance Corporation, to rate solar panel manufacturers in terms of financial stability, again , Tier-1 NOT a reference to solar panel's quality or performance. This is why a manufacturers reputation and history are just as important as their perceived quality.

We mainly market Duel-axis and Single-axis Solar Trackers (DAT/SAT), that automatically follow the Sun from dawn to dusk, we don't offer Rooftop solar panel Racking (your installer may offer there own preferred Roof-top railings & brackets).

Flat mounted & Fixed Tilted panels, are inefficiently harvest the suns peak energy for approx. 3~4.5 hours per day (depending on location), where DAT peak energy harvesting starts at 9.5~12.5+ hours per day, depending on your latitude location.

NB: Our DAT units are over engineered, & are easily transportable, bar the foundation/pole !

We offer customers the latest Solar Panel & Cell technology, being 12 Wire Bus Bar Cells (12BB), reflective PERC & Half panel Technology (166x92x35cm =1.52m2), these panels offer a combination of raw material like low-iron glass and special soldering process, that benefit the pv cell with much less mechanical stress, which lowers the risk of hot spots, degradation and micro cracks. All improvements are aimed to gets a much longer durability of the cell/module.

Those selling old 5 Bus Bar, 270W, 60cell Polycrystalline &/or Monocrystalline solar panels are selling customers short, as 350W/500W panels harvest 30%/85% more energy, than 270W panels, 270W panels (164cm x 99cm =1.63m2) use 15%/37% larger footprint (racking area) to harvest the same kWh energy!

However: All Quality solar panels should last 25+ years, 270W panels just won't harvest the same energy, thus taking way longer to reach your break-even investment time, before providing ongoing profit!

The Solar Credits program is part of Australia’s Renewable Energy Target. Where every megawatt hour of qualifying energy generation is eligible for renewable energy certificates (REC). These certificates come in two types: Large-scale (REC) and Small-scale (STC) certificates, STC certificates are the ones that apply to Residential solar installations.

If you happen to purchase 60cell, 6kW+ Solar Specials offered on TV or the Web, we really don't care, BUT read the small print, as we suggest you ask them the cost difference to install a Hybrid inverter, as after the installation you will find you have been sold a Solar Only inverter, meaning, if you later install batteries, you will need to purchase a $350 odd AC converter or AC switching gear, that in turn cost more and uses additional power to operate.

NB: We only supply quality Mono-crystalline 350W (72 cell, 196cm x 99cm =1.94m2) and 500W (96 cell, 196cm x 131cm =2.57m2) Solar Panels, and DAT units, DAT units & Batteries are a bigger part of the disruptive force currently happening in the energy market!

The biggest marketing spin/cons of many Solar companies is, they say words to the effect;

  • "Tear-1 Panels are the best !". That is incorrect, "tier1 panels", simply means the supplier/manufacturer sold the most panels, and that is Not a true indication of panel quality. Always go for Panel Manufacturer that Manufacturers there own PV Cells!
  • The best size solar array is 6kW array! A marketing spin based on 'Small-scale technology certificates' (STC), as these companies are looking to claim Your STC or REC.
    6kW array is Not really correct, 'unless your daily Sun-rise to Sun-set energy usage is close to 30kWh' !
    Purchasing less solar panels & invest the savings on Battery storage, this in it's self will save you paying in most cases 300% more than any rebate, for the power you consume after sunset, it is that simple!
  • STC are based on the amount of panels install, the more money the suppliers/installers claimed back.
    However, what many companies/installers don't tell you when you sign over your STC, they claimed your STC as there little cash stash, the STC are usually way more than the installation costsNew Window, this is Not widely stated, ring around and ask for a cost breakdown inc. what the installers/installation cost are, for the system you are looking to purchase.

Understand that STC & REC can be claimed back by the system ownerNew Window, up to 12 months after installation, from 2019 you can claim up to 12 years worth of STC or REC, due to end in 2030New Window.

If a company has the customers best interested at the forefront, they would be advising you to purchase a solar array equal to your daily power consumption, and battery storage to cover sunset to sunrise consumption, it's very simple to add panels at any time.

This is where things get more complicated, we will try to make this simple;

  1. In Australia a 5kW inverter is generally the largest most Retailers say you can install, there is no real restriction on the size of the solar array, people with a large array will be supplying there Non solar neighbours with there power.
  2. All Tilted roof-top solar panels, will only harvest 4~4.5 hours maximum peak energy per day!
    This is where Batteries & DAT, become a serous game changer!
  3. Where a DAT unit will harvest energy for 10~11 hours day, double the energy, & requires less panels.
  4. So, before you purchase your energy system, we advice you take the 'reading of your power meter just before sunset, and again at sunrise', this is Very important, as it tells you the minimum kWh size Battery you premises requires to become power independent.
  5. Batteries should rarely support your power usage during the day, except for in a blackout or extended bad weather conditions, Battery are commonly used for power demands after sunset, providing you with overnight power independence!

So Remember: A Solar array matches to your 24 hour power consumption, instantly allows you to eliminates your daytime power bill - Although the real savings only start when you store the excess power in a battery, and harvest it after sunset, it is that simple!

Yes, 350W & 500W panels cost a little more, but calculates out to approx. the same cost per Watt, as the old 270W panels, the main advantage is the larger Wattage panels considerably increase the daily kWh harvest rate, and also reduce the break-even time line considerably quicker!

There are also 400~490W Bi-facial (clear & opaque double sided) solar Panels that generate power from both sides, this is done by harvesting up to 20% more Power via harvesting Reflective light from the surrounding ground/area, these panels can be installed in areas like foyers & walkways, that would normally have glass windows.

Things are changing rapidly in the solar world, so don't be fooled into purchasing 270W panels, even though these older panel technology should/will last 25 years, they just require a larger footprint !

Types of Solar Panel Installation;

Fixed Flat or Tilted Solar Arrays: Are the lease effective at harvesting energy !

Single-Axis Solar Tracking Arrays: Increase energy harvest by over 30%, SAT can be configured to Track East~West Vertically or Horizontally.

Dual-Axis Solar Tracking Arrays: Are capable of harvesting up to 100% more power than fixed flat panel arrays.

NB: With DAT the further South (or North) of the equator increases the solar harvesting time up to 14 hours south of Hobart, Tasmania, where Brisbane, QLD that will be approx. 10 hours peak sun.

With most things it comes down to Cost, cost modelling show that Labour to install Fixed & Fixed Tilt PV systems are the cheapest, followed by Single Axis Tracking then Dual Axis Tracking system is least competitive to install, however the initial material & installation cost difference is recovered quite rapidly with SAT and more-so with DAT, as the increased harvesting commonly reaches the break-even period to recover the additional installation cost incurred in approx. 12 months, irrelevant on the size of the PV array!

Not all technologies preformed equal, as labour costs for installation play a large part of initial and final cost competitiveness. It also demonstrated how Low Cost of Energy (LCOE) can underpin a commercial ‘Contract-for-Difference’ (CFD) feed-in tariff scheme applicable to supporting investment in utility-scale solar farms.

The key issue for either residential or commercial solar system, is producing the best financial return in the quickest time, in an off-grid system, this is done by storing what would normally be unused/wasted Solar energy into a battery bank or thermal storage system.

Battery storage does two things, contribute to black-out proofing your home or premises after sun-set, where if you are grid connected, the excess energy will first charge your batteries, before exporting any excess energy into the state grid for a FIT, and as such minimising paying the deceptive electricity retainers for power after sunset, and battery storage energy also reduce the reliance on fossil fuels, to ensure a brighter future for our planet!

Few people know that Solar harvesting & storage has the potential to provide over 1,000 times the total world energy consumption, though in 2017 Solar provided less than 1% of the total power used.   Installing solar contributes to increasing that figure.

What is the best installation angle for Fixed & Single-axis solar panels ?

The latitudinal tilt angle of fixed panels directly relate to angle of the sun in the sky, and depends on both the season and your location on the planet.

In Winter the sun is Lower in the sky, and in Summer the sun is Higher in the sky.

The closer you live to the equator, the higher the sun is in the sky all year round, & the lower your degree of latitude tilt is).

NB: DAT is excluded, as the array is automatically tilted perpendicular (straight at) to the Sun !

So, calculating the optimum tilt for fixed tilted panels on your roof is actually dead simple.  To maximize the power produced over the whole year, all you need to do is set the angle for your solar panels, to the latitude of your location as shown below;

Remember: DAT can harvest over 45% more energy from the sun than flat fixed panels, and the further South you live, DAT increases the harvesting of energy for a longer period each day!


A New Super Solar Cell invented at the Australian University of New South Wales (UNSW), has gained the world efficiency record of over 40%, these solar cells are made from Gallium Arsenide, not Silicon like in conventional solar panels.  Due to past cost restrictions Gallium Arsenide solar cells were only used in space exploration and Satellites, a single 2kWh Gallium arsenide Super cell measure approx. 10cm x 15cm and replaces Six (6) 340w (2mt x 1mt, 72cell) Solar Panels when used in conjunction with Heliostat mirrors.   After receiving a million dollar government grant, RayGen, an Australian company has developed & is now manufacturing scalable commercial solar arrays.

In 2019, one promising solar cells technology is being manufactured/use, from/with a base of common Crystalline silicon with additional thin film layers of Amorphous silicon on either side of the cell, forming what is known as the heterojunction. As opposed to the common P-N junction cells.  The multi-layer heterojunction cells have the potential to drastically increase efficiency with lab testing achieving efficiencies up to 26.5% when combined !
