Canadian Solar Denies Copying of TOPCon Technology from Maxeon

By Editor


Canadian Solar, a global solar product manufacturer, has issued a statement in response to a recent patent infringement lawsuit filed by Maxeon Solar in the U.S. District Court in the Eastern District of Texas.

The lawsuit between Maxeon Solar vs Canadian Solar alleges that Canadian Solar is infringing on three patents owned by Maxeon related to tunnel oxide passivated contact solar photovoltaic module technology, commonly known as TOPCon technology.

Canadian Solar said it manufactures and sells various types of solar products worldwide, including TOPCon solar modules. Canadian Solar has filed and received thousands of patents across different jurisdictions for solar cells and related technology.

While Canadian Solar assesses Maxeon’s complaint with legal counsel, the preliminary assessment by the company suggests that the claims made in the lawsuit lack merit. Canadian Solar denies any infringement of Maxeon’s patents by its TOPCon technology and pledges to defend itself against the allegations. Canadian Solar anticipates vindication in court at the appropriate juncture.

Maxeon Solar Technologies in a news statement said the innovations behind Maxeon IBC, Shingled Hypercell, and TOPCon technologies are protected by a global patent portfolio of over 1,650 granted patents and over 330 pending patent applications.

Maxeon has many patents related to TOPCon technology, with inventions drawn to fundamental TOPCon solar cell architectures dating back to the 2000s. “This is Maxeon’s first action to enforce its valuable patent rights in the United States, and Maxeon will continue to vigorously enforce its patent rights in the United States and its other markets,” said Marc Robinson, Associate General Counsel at Maxeon.

Canadian Solar on September 11, 2023 announced it received the Canadian Solar TOPCon Technology Review Report from DNV, a third-party expert in product certification, risk management, and assurance. Canadian Solar’s TOPCon 210 mm and 182 mm cell-based bifacial modules have been considered by DNV as having high reliability and low LCOE. News Desk
