French company HoloSolis has successfully raised over €220m in financing to support the construction of a new solar panel factory, which the firm states will be one of the largest in Europe.

The development comes as solar energy remains a central pillar of European strategy to boost environmentally friendly power sources and reduce reliance on external energy supplies.

The HoloSolis project, located in Sarreguemines-Hambach, is slated to become fully operational by 2030. It aims to achieve an annual production capacity of 5GW, which is projected to generate enough power for one million homes.

Furthermore, the initiative is expected to create 2,000 direct jobs.

The recent financing round involved several key companies, including Cales Technologie, InnoEnergy, TSE, Groupe IDEC, Armor Group, and Heraeus.

InnoEnergy France CEO Karine Vernier stated, “HoloSolis embodies the ambition we have had since day one: a strong and sovereign European solar industry.”

The financial commitment is a major step toward establishing the large-scale production necessary to meet the region’s ambitious clean energy targets.
