Maxeon Solar Technologies and Hanwha Solutions, which operates under the Qcells brand, have reached a global settlement to end all patent disputes between the two companies. The agreement brings an end to a legal battle that had attracted significant attention in the solar industry and removes uncertainty surrounding advanced solar technology patents.
The dispute began in April 2024 when Singapore-based Maxeon Solar Technologies filed a lawsuit against Hanwha in the U.S. District Court for the Eastern District of Texas. Maxeon alleged that Hanwha’s Q.ANTUM NEO solar cell technology and Q.TRON solar modules violated its intellectual property rights. The case focused on Tunnel Oxide Passivated Contact (TOPCon) technology, which is widely regarded as one of the most advanced solar cell technologies available today. TOPCon technology helps solar panels achieve higher energy conversion efficiency and better performance in challenging weather conditions, including high temperatures, humidity, and cloudy environments.
Maxeon claimed that the technology was originally developed by its predecessor, SunPower, and sought financial compensation along with an order to stop Hanwha from selling the products in the United States. Hanwha denied the allegations and challenged the validity of Maxeon’s patents through the U.S. Patent and Trademark Office.
Before the Texas court could issue a final decision on the case, both companies agreed to settle the dispute and jointly requested the court to dismiss the lawsuit. As part of the settlement, the court dismissed Maxeon’s patent infringement claims with prejudice, meaning the company cannot bring the same claims against Hanwha in the future. Hanwha’s counterclaims and legal defenses were dismissed without prejudice, allowing the company to raise them again if similar issues arise later. Both companies also agreed to bear their own legal and attorney expenses.
The settlement removes a major legal hurdle for Hanwha as it continues to strengthen its presence in the North American solar market. The company is investing approximately $2.31 billion in its Solar Hub project in Georgia, which is expected to become the largest integrated solar manufacturing facility in North America. Qcells said the agreement confirms the originality of its TOPCon technology and allows it to focus on expanding domestic solar manufacturing. For Maxeon, ending the legal dispute enables the company to move beyond a series of patent battles and concentrate on its business growth and future opportunities in the global solar market.
