Holosolis

France-based Holosolis is a solar developer that was founded by three European entities: EIT Innoenergy, a clean-tech investor based in the Netherlands and financed by the EU; IDEC Group, a real estate developer in France; and TSE, a prominent solar energy producer in France and a leader in agrivoltaics. 

Holosolis is committed to manufacturing energy efficient modules using the latest photovoltaic technologies, with the lowest carbon footprint and highest social standards. It plans to build a state-of-the-art module gigafactory in Sarreguemines, Moselle, France, that will start production in 2025. It aims to produce 10 million PV panels per year.

Holosolis will accelerate innovation across the entire photovoltaic value chain, from raw materials to recycling, with products designed for the following markets:

* Residential rooftops
* Industrial and commercial rooftops
* Agrivoltaics
* Utility scale

In 2023, German silver metallization paste maker Heraeus acquired an unspecified stake in HoloSolis. Also, Germany’s Fraunhofer Institute for Solar Energy (ISE) said that it will support HoloSolis in setting up its planned manufacturing facility.

In November 2023, Armor Group acquired a 20% stake in HoloSolis. Also, Holosolis marked its entry into perovskite-silicon tandem panel production, after abandoning organic solar module production.
