It is a privately held, US-owned company. SEG Manufacturing Inc. operates as part of SEG Solar Inc., alongside affiliates like New Energy Imports Inc., PT. SEG Solar Manufaktur Indonesia, and SEG Energy Singapore Pte. Ltd. As of late 2024, SEG Solar had shipped over 6 GW of solar modules worldwide and had a module production capacity exceeding 6 GW. In May 2026, the company announced a new 4-gigawatt (GW) solar module manufacturing facility in Houston, an investment of over $200 million expected to create 800 new jobs and increase their total annual U.S. module production capacity to approximately 6 GW.

SEG Manufacturing Inc. is currently a plaintiff in one tracked case, "SEG Manufacturing Inc. et al. v. Zhejiang Jinko Solar Co Ltd et al.," filed in the Patent Trial and Appeal Board (PTAB) on February 18, 2026. This indicates an active posture in defending its intellectual property or challenging that of competitors. The PTAB case is related to a patent infringement complaint filed by Jinko Solar against SEG Solar in the U.S. District Court for the Southern District of Texas in late 2025, alleging infringement of a patent related to N-type TOPCon technology.
The PTAB case "SEG Manufacturing Inc. et al. v. Zhejiang Jinko Solar Co Ltd et al." involves multiple SEG entities as petitioners, including SEG Manufacturing Inc., New Energy Imports Inc., SEG Solar Inc., PT. SEG Solar Manufaktur Indonesia, and SEG Energy Singapore Pte. Ltd. This case is part of a broader patent dispute where Jinko Solar alleges infringement of its US Patent No. 11,824,136, which covers solar cells and their manufacturing methods, specifically N-type TOPCon technology. SEG Solar has stated its intention to vigorously defend against these claims, asserting that its N-Type cell technology does not infringe Jinko's patent.
