HoloSolis, the French producer of low carbon PV cells and modules, has secured over €220 million in private and non-private funding to construct certainly one of Europe’s largest photo voltaic gigafactories in Sarreguemines-Hambach.
Backed by Calés Technologie and Forming, and long-standing buyers together with InnoEnergy, TSE, Groupe IDEC, Armor Group, and Heraeus.
Bertrand Lecacheux, CEO of HoloSolis says: “HoloSolis already had robust companions: InnoEnergy, Armor Group, IDEC, TSE, and Heraeus. I’m very proud that new companions are becoming a member of us! We can profit from their experience to construct the most important TOPCon cell and module gigafactory in Europe. A number of photovoltaic builders have chosen to put money into the challenge and we now have a complete of greater than 20 GW of buyer letters of intent, which demonstrates the power of our enterprise mannequin.”
In 2025, a number of European startups energetic in photo voltaic and adjoining energy-transition fields secured new funding, providing context for HoloSolis’ newest increase.
France noticed exercise by way of Solarock, which collected €7 million to increase its photo voltaic self-consumption franchise mannequin, and Dracula Applied sciences, which prolonged its Sequence A to €30 million to industrialise ambient-light power modules. In Germany, feld.power raised greater than €10 million to scale dual-use agrivoltaics, whereas Co-Energy secured €6.4 million for on-site storage and industrial PV deployment. Within the Baltics, Estonia’s Sunly obtained practically €85 million to construct large-scale Latvian photo voltaic parks.
Altogether, these rounds quantity to roughly €108 million – considerably beneath the greater than €220 million secured by HoloSolis, highlighting the comparatively bigger capital necessities related to European PV manufacturing scale-up.
Karine Vernier, CEO of InnoEnergy France provides: “HoloSolis embodies the ambition we now have had since day one: a powerful and sovereign European photo voltaic business. Seeing this challenge attain a decisive milestone with greater than €200 million secured is a supply of immense satisfaction for InnoEnergy, a long-standing investor dedicated to the power transition.”
HoloSolis was created in 2022 to reshore PV manufacturing in Europe. HoloSolis manufacturing of PV cells and modules might be a solution to the urge for food of EU PV builders for European made panels created by the brand new European and Nationwide laws.
Due to its dimension, HoloSolis will reportedly carry a sustainable and aggressive different to PV Panels at the moment available on the market.
Jean-Paul Calès, President of CALES TECHNOLOGIES says: “Investing in HOLOSOLIS affirms our conviction that the power transition have to be supported by a high-performing, revolutionary, and accountable French business. By our subsidiaries, we’re dedicated to selling nationwide industrial experience and actively contributing to a extra sustainable and sovereign economic system.”
The challenge is ready to generate 2,000 direct jobs and attain a manufacturing capability of 5 GW per 12 months. As soon as absolutely operational by 2030, the plant will produce sufficient photo voltaic modules every year to energy a million European properties, representing a major milestone for Europe’s power independence.
The funds might be used to finalise the design of the manufacturing facility, deploy TOPCon know-how, and help recruitment and supply-chain setup.
In doing so, HoloSolis contributes to constructing a completely “Made in Europe” photo voltaic manufacturing ecosystem and strengthening Europe’s power sovereignty. The HoloSolis facility will assist Europe to succeed in its purpose of getting 40% of PV deployed in Europe to be made in Europe, as set by the Web Zero Business Act.
Eric Lauer, Strategic Growth Supervisor at Forming AG shares: “Supporting the reindustrialisation of France is on the coronary heart of Forming AG’s ambitions! Past this funding, Forming will contribute its experience within the interface between photovoltaic panels and buildings to enhance their efficiency.”
HoloSolis has secured all of the permits it must launch development of its plant in 2026:
– 15 Might 2024: signing of the land acquisition contract for the location in Hambach
– 17 Might 2024: signature with RTE for a high-voltage connection in 2027
– 24 January 2025: constructing allow and environmental authorization obtained
– 3 September 2025: technological partnership signed with world PV chief Trina Photo voltaic
– 17 November 2025: HoloSolis proclaims new buyers
Franck Leroy, President of the Grand Est Area says: “This can be a decisive step ahead for HoloSolis’ gigafactory challenge in Hambach: greater than €200 million secured and strengthened partnerships verify that it’ll enter the operational part in 2026. I wish to commend the professionalism and ongoing dedication of the HoloSolis groups. This challenge contributes to Europe’s power sovereignty and the reindustrialisation of our areas, with 1,700 jobs at stake.“
