REC US Holdings, Inc. is a Delaware-incorporated holding company that is a wholly-owned subsidiary of REC Solar Holdings AS, a Norwegian-founded solar energy company. REC Solar Holdings AS, also known as REC Group, was established in 1996 and has operational headquarters in Singapore, with regional hubs in North America, Europe, and Asia-Pacific. As of December 2021, REC Group is a wholly-owned subsidiary of Reliance Industries Limited, a diversified Indian conglomerate. REC US Holdings, Inc. itself was a non-operating entity with no turnover in 2025 and an almost negligible net worth contribution to its parent company's consolidated finances. It was dissolved effective July 6, 2026, as a housekeeping measure by its parent company.

REC Group manufactures solar panels and provides solar energy solutions for residential, commercial, and utility-scale customers. Their product lines include the REC Alpha Pure-R, REC Alpha Pure, and REC N-Peak 3 Series, which utilize advanced technologies like heterojunction (HJT) and half-cut cells for high efficiency and power output. They are involved in the integrated manufacturing process from raw silicon to completed panels.

REC US Holdings, Inc. appears as a plaintiff in one tracked case, REC Solar Holdings AS et al. v. Maxeon Solar Pte Ltd., before the Patent Trial and Appeal Board (PTAB), filed on February 14, 2025. This indicates a posture of asserting its intellectual property.

The PTAB case is part of broader patent litigation activity for REC Solar Holdings AS. Maxeon Solar Technologies initiated a patent infringement lawsuit against REC Solar Holdings AS in the Eastern District of Texas on April 19, 2024, alleging infringement of patents related to TOPCon solar cell technology. However, this District Court case was dismissed without prejudice on June 25, 2025, suggesting a negotiated resolution. Previously, REC Group was involved in a patent infringement lawsuit with Hanwha Q Cells. REC Group filed a patent infringement lawsuit against Hanwha Q Cells in the U.S. District Court for the District of Delaware in November 2020, related to its split cell and junction box technology. REC Group had successfully defended against a prior patent infringement claim initiated by Hanwha Q Cells in 2019 concerning PERC solar cells, which resulted in a ruling of non-infringement in favor of REC by the International Trade Commission and was affirmed by the Federal Circuit.
