  • Trinasolar and its South Korean rival, Hanwha Qcells, have revealed that they have reached a settlement agreement on a patent dispute that the Chinese module maker initiated in January.

In a joint statement, the two companies said they reached a patent licensing and transfer agreement over their intellectual property.

“The agreement allows both parties to use each other’s solar patents and respectively drop all pending cases between the two companies,” they said. “To meet the needs of customers, each company will continue to offer and support their respective products in various markets.”

Trina Solar said in a patent infringement lawsuit against Hanwha Qcells (Qidong), a Chinese unit of  Hanwha Qcells, that the South Korean company had unlawfully exported and sold solar modules that infringed upon a patent granted to the Chinese manufacturer by the China National Intellectual Property Administration in 2016.

“The lawsuit involves the core cell technology commonly used in Hanwha’s current modules produced in China and sold globally,” a Trina Solar spokesperson told pv magazine at the time. “The alleged infringing products include Q.PEAK DUO BLK M-G11A+, Q.PEAK DUO M-G11 and other key products.”

If Trina Solar had succeeded in proving its claims in China, Hanwha Qcells could have been prohibited from producing and selling the infringing products in China and other countries. It may have also faced high infringement compensation costs for past production and sales. 

In December, a German court issued a preliminary injunction that ordered Trina Solar to stop selling its Honey and Vertex X solar modules in Germany, as they allegedly infringed upon the patented passivation technologies of Hanwha Qcells.

In late October, Hanwha Solutions filed a preliminary injunction request in which it claimed that Trina Solar (Germany) had been improperly selling solar modules in the German market. It said that the Trina Solar panels infringed upon one of its own patents for its proprietary Q.ANTUM passivation technology. It said the technology plays a key role in improving the performance of silicon-based solar cells
