European Commission Selects HoloSolis For Major Solar Manufacturing Funding
The French solar factory project is among 77 net-zero initiatives receiving support from the EU Innovation Fund.
The European Commission has selected 77 net-zero technology projects across 23 countries to receive a total of €3.4 billion in funding through its Innovation Fund. Among the recipients is the SOLAR4EU project, led by HoloSolis, which plans to construct a 5 GW integrated solar cell and module manufacturing facility in Hambach, France. The initiative aims to strengthen the European solar value chain and decrease reliance on non-EU imports.
HoloSolis intends to utilize highly automated production lines to manufacture n-type TOPCon modules, with an annual production target of 10 million panels. The project, which is supported by the IDEC Group, TSE, and EIT InnoEnergy, is expected to create more than 2,000 jobs. The company has also obtained a TOPCon patent license from Trinasolar to facilitate its manufacturing operations.
The funding round includes 12 clean technology manufacturing projects, which have requested a combined €895 million to support the production of solar panels, heat pumps, electrolyzers, and electric-vehicle batteries. Other selected solar-related projects include the ReGAIN initiative by UMICORE SA in Belgium, which aims to establish a pilot production line for circular germanium foils used in high-performance solar cells.
In Greece, the TALOS project by ANONIMI ETAIRIA DIAXEIRISIS ANANEOSIMON PIGON ENERGEIAS will develop a renewable microgrid on Crete. This project will integrate solar and wind farms with a 400 MWh solid-flow battery energy storage system. The system is designed to provide 40 MW of power for approximately 10 hours, helping to displace diesel generation and improve grid stability. Additionally, EDF Renouvelables will implement the BESS-4-C project in Perquie, France, to manage grid congestion by storing excess solar energy.
Large-scale battery manufacturing projects also received support, including PowerCo Battery’s plan for a 27 GWh per year lithium iron phosphate cell factory in Spain and LG Energy Solution’s 9 GWh per year facility in Poland. These selected projects will now begin grant agreement preparations with the European Climate, Infrastructure and Environment Executive Agency (CINEA), with results expected in the first quarter of 2027.
The European Commission has now committed approximately €17 billion to around 320 projects through the Innovation Fund. A new round of funding, totaling €1 billion, is scheduled for early December 2026 to support clean tech manufacturing and supply chain security under the RESourceEU Action Plan. This plan seeks to reduce the European Union's dependence on third countries for critical raw materials, including lithium, by 2029.
