Holosolis

Holosolis SAS, established in 2022, is positioned to become a significant force in the European photovoltaic (PV) manufacturing sector, addressing the continent's strategic objective of energy sovereignty. The company was founded by a consortium of three entities: EIT InnoEnergy, an EU-backed clean-tech investor; IDEC Group, a French real estate developer; and TSE, a major solar energy producer in France. This venture aims to reindustrialize Europe's solar sector and reduce its heavy reliance on Asian imports, which currently account for over 95% of its solar panels.

The company's primary operation is the construction and management of a large-scale solar PV module gigafactory in Hambach, Moselle, France. This facility represents a total investment of approximately €700-€850 million. Construction is planned to begin in mid-2025, with initial production slated for 2026 and the factory reaching its full 5 GW annual capacity by 2027-2029. Once fully operational, the plant is expected to produce 10 million photovoltaic panels annually, enough to power about one million European homes and create approximately 1,700 direct jobs. The business model is centered on the large-scale manufacturing and sale of PV modules to a diverse client base that includes residential, commercial, industrial, and agrivoltaic sectors across Europe. The strategic location in northeastern France allows for efficient service to key markets like Germany, Italy, the Netherlands, and Austria.

Holosolis's product strategy is focused on high-efficiency solar modules based on Tunnel Oxide Passivated Contact (TOPCon) technology. This choice was made due to TOPCon's market maturity, lower industrialization costs, and reduced use of rare earth materials and silver compared to alternatives like Heterojunction (HJT) technology. The company's R&D team is also exploring next-generation technologies like perovskite-silicon tandem cells to enhance future product efficiency. Holosolis has secured strategic partnerships and investments from key industry players, including German metallization paste maker Heraeus and French thin-film technology expert Armor Group, which acquired a 20% stake. It also collaborates with the Fraunhofer Institute for Solar Energy (ISE) on technology and factory planning. These partnerships are intended to bolster technological development and commercial reach.
