  • Please tell us above about your power situation. Simply click on the phrase that best describes your situtation.

The main parts of your system are comprised of:

  • Solar panels (capture energy),
  • Solar panel inverter (converts electricity),
  • Battery and battery inverters (charge and store energy).

All our systems use components from large established companies. We recommend the use of high-quality components for systems installed in Australia’s tough weather conditions.


SOLAR PANELS

All of our solar packages use Tier 1 solar panels. These are high-quality solar panel companies, all in the top 5 solar manufacturers globally, have excellent product and performance warranties, and are used in most of the big solar installations around the world. These are all excellent panels and are recognised as being very high-quality panels across the solar industry.

Founded in China in 2006, Jinko Solar is today one of the largest manufacturers of photovoltaic (PV) panels in the world, having sold its products to 59 countries in 2014. Jinko Solar subjects its products to more stringent tests than other manufacturers. This ensures that their panels can handle anything that the Australian climate throws at them and will continue to do so for many years.

An example of this is JinkoSolar being the first Chinese manufacturer to receive the Qualification Plus (Q+) certification from TÜV Rheinland. TÜV Rheinland does independent certification for solar modules. To be able to install solar panels in most countries (including Australia), the panels need to meet IEC61215 and IEC61730. The Q+ by TÜV Rheinland is a far more rigorous test, particularly for mechanical robustness which is very important in Australian conditions. It also tests hot spots, insulation and wet-freezing cycle.

The JinkoSolar panel has excellent low-light performance and high-heat tolerance compared to other popular modules in tests. This is very important, as panels spend much more time in the lower light than in perfect lighting conditions. In fact, panels will never find themselves in the same conditions as the testing chamber by which it receives its nameplate output – Standard Test Conditions (STC). The JinkoSolar panel performs better in more realistic conditions, with a higher output at Nominal Operating Cell Temperature (NOCT) than other panels. This is one of the main reasons why two panels with the same peak or nameplate performance can differ in yearly yield.

For added peace of mind and to ensure transparency with the Australian market, JinkoSolar has invited the Australian Solar Council into its factory to conduct independent inspections for the Positive Quality program. This is completely voluntary and provides consumers further confidence in knowing that the Australian Solar Council has inspected the facility and confirmed that such products are an excellent fit for the Australian market.

There are many other small benefits that make JinkoSolar panels perfect for our conditions, such as lower temperature coefficients, good weak-light performance and Potential Induced Degradation (PID)-free panels at 85 degrees. This is why many households in Australia and the world are choosing JinkoSolar, the world’s largest producer of solar panels. Not only are homes choosing JinkoSolar, but utility-scale projects too. JinkoSolar panels were chosen for the 1.8MW farm in Uluru – the harshest of Australian conditions. With all the benefits of these panels, the confidence in choosing panels selected for solar farms in the desert, and award-winning performance in reputable tests like this one from Choice and the CSIRO, it’s no wonder the JinkoSolar panel is one of Australia’s most popular and best value-for-money panels.

JinkoSolar has been named in September 2018 the most “bankable” PV manufacturer by Bloomberg New Energy Finance (BNEF) among 57 module brands.

BATTERIES

LEAD CARBON

Narada was established in 1994 in Hangzhou/China. They have become one of the leading battery manufacturers and global battery suppliers of the world. In 2010 Narada Power Source Co., Ltd went public on the Shenzhen Stock Exchange.

Narada is one of the few companies in the world that has mastered the core technologies of lead-carbon batteries. Through the exploration of commercial energy storage by Narada, it has been clarified that the application of electrochemical energy storage has matured in terms of scale, safety, economy, etc., and has formed a large-scale application.

In May 2018 Bloomberg Finance released the global ranking of 2017 energy storage battery vendors based on the database of energy storage projects of Bloomberg New Energy Finance. Narada had the second largest energy storage capacity in 2017.

REXC series, under name of REX Carbon, is lead-carbon battery developed from REX series. Combine world advanced lead-carbon technology and REX VRLA technology, REXC lead-carbon battery extra-long cycle life, special in a partial state of charge (PSoC) cycle, significantly faster recharge rates and large current discharge performance. REX Series is mainly designed for energy storage system, a hybrid system.


LITHIUM-IRON

BYD as the world leading energy solution provider is now supplying energy products to more than 30 countries and regions in five continents except Antarctica. BYD has extensive experience in the energy storage sector for large-scale systems and electric vehicles (largest EV manufacturer in the world) and has product solutions perfect for the residential Off-Grid sector.
