Hanwha Q CELLS is proud of our legacy of innovation and believes strongly in protecting our intellectual property.


Hanwha Q CELLS Australia Pty. Ltd., together with Hanwha Q CELLS & Advanced Materials Corp, filed patent infringement complaints with the Federal Court of Australia against JinkoSolar and LONGi Solar. The complaints allege that JinkoSolar and LONGi Solar are importing and selling solar cells and modules that infringe Hanwha Q CELLS’s Australian patent rights. In particular, the complaints allege that JinkoSolar and LONGi Solar have incorporated Hanwha Q CELLS’s patented passivation technology—which plays an important role in improving the efficiency and performance of solar cells—into their solar cells. Hanwha Q CELLS seeks an order to stop JinkoSolar and LONGi Solar from importing, marketing, and selling the infringing products in Australia.


In the United States, Hanwha Q CELLS & Advanced Materials Corp. and Hanwha Q CELLS USA Inc. filed a patent infringement complaint with the U.S. International Trade Commission (“ITC”) and Hanwha Q CELLS & Advanced Materials Corp. filed related infringement complaints with the U.S. District Court for the District of Delaware against JinkoSolar, LONGi Solar, and REC Group.


In Germany, Hanwha Q CELLS GmbH filed patent infringement complaints with the Regional Court of Düsseldorf against JinkoSolar and REC Group.


Hanwha Q CELLS’s patented passivation technology improves the efficiency of light conversion into electricity, allows more energy to be extracted from the solar cell, and enables it to remain durable through the manufacturing process. Hanwha Q CELLS began manufacturing Q.ANTUM solar cells using this passivation technology in 2012 and has produced more than 2.5 billion such cells globally.

Presence in Australia

Australia is one of the global leaders in the solar energy sector and Hanwha Q CELLS is fully committed to further strengthening this important industry. Last year, approximately one in 10 panels installed in the country’s residential and commercial segments were made by Hanwha Q CELLS. To learn more about our presence in Australia, click here.


Hanwha Q CELLS’s presence in Australia goes back to 2009. Australia has the highest average solar radiation per square metre of any continent in the world. And with its vast size, Australia is comprised of a multitude of climate regions. These can range from some of the most pleasant to some of the harshest climate conditions in the world.


Hanwha Q CELLS panels are specifically designed and tested for Australian conditions to ensure optimal performance. Our modules work reliably, regardless of environment.
