Jiangsu Runergy New Energy Technology Co., Ltd.

Jiangsu Runergy New Energy Technology Co., Ltd. (often referred to as Runergy) is a Chinese photovoltaic (PV) technology company founded in 2013 and headquartered in Yancheng, Jiangsu Province, China. The company specializes in the research, development, manufacturing, and global distribution of high-efficiency solar cells and modules, with a focus on N-type technology. Runergy is a private company, though there was an announced plan for Tongwei to acquire a controlling stake in August 2024, which was later dropped in February 2025. Runergy is recognized by BloombergNEF as a Tier 1 PV module manufacturer. By the end of 2023, Runergy had a planned capacity of 63GW for cells and 23GW for modules globally. The company has an extensive network of production facilities for polysilicon, wafers, cells, and modules across China, Thailand, Vietnam, and the United States, including a module manufacturing facility in Huntsville, Alabama. Some sources indicate Runergy has over 10,000 employees globally.

Runergy's main product lines include high-efficiency N-type and P-type solar cells and modules, such as bifacial N-type TOPCon solar panels. The company also offers comprehensive solar project solutions. Runergy has established collaborations with research institutions like Fraunhofer ISE (Germany) and UNSW Australia for R&D. According to InfoLink Consulting, Runergy ranked among the global top 3 in solar cell shipments for three consecutive years from 2020 to 2022.

In terms of patent litigation, Jiangsu Runergy New Energy Technology Co., Ltd. appears to be an operating company defending its products. The company has been named as a defendant in two tracked cases and has not initiated any plaintiff cases. Both lawsuits were filed by Trina Solar, with one in the U.S. District Court for the Central District of California (filed 2024-09-10) and the other in the US International Trade Commission (ITC) (filed 2024-09-30). These cases indicate a defensive posture against alleged patent infringement.

A notable context for these cases is the broader patent dispute within the solar industry, particularly concerning TOPCon technology. In a related development, in April 2026, the US Patent Trial and Appeal Board (PTAB) declared key claims from two Trina Solar patents, previously asserted against companies including Runergy and Canadian Solar, as invalid. This decision could impact the ongoing litigation by removing a significant legal hurdle for Runergy and other companies in the US market.
