Headquartered in Changzhou, Jiangsu, China, it is a publicly traded company on the STAR Market of the Shanghai Stock Exchange under stock code 688599.

Trina Solar is a vertically integrated provider of smart solar energy solutions. Its main businesses include the research, development, production, and sales of photovoltaic (PV) modules, offering a wide range of energy storage solutions for various applications, providing system solutions such as trackers and power plants, and delivering digital energy services including O&M and microgrids. The company manufactures solar wafers, cells, and modules, and is recognized for its Vertex series of modules utilizing 210mm wafer technology and n-type TOPCon cells.
In terms of patent litigation, Trina Solar acts as an active operating company asserting its intellectual property. The company has appeared as a plaintiff in two tracked cases and has no defendant cases in our database. Both tracked cases were filed in the US International Trade Commission (ITC), a venue often chosen by companies seeking import exclusion orders for alleged infringement. Trina Solar owns more than 2,000 patents, including a significant number related to its N-type TOPCon technology.
Notable cases include Trina Solar v. Canadian Solar defendants, filed on October 23, 2024, at the US ITC, and Trina Solar v. Adani Green Energy Ltd. et al., filed on September 30, 2024, also at the US ITC. The dispute with Canadian Solar involved allegations of infringement concerning Trina's TOPCon solar cell technology patents, with Trina seeking a limited exclusion order and a cease-and-desist order. However, the U.S. Patent and Trademark Office (USPTO) has since invalidated all claims of two TOPCon solar cell patents previously asserted by Trina Solar against Canadian Solar subsidiaries in April 2026, which effectively halted parallel district court proceedings.
