Description
HoloSolis will build Europe’s largest and most efficient photovoltaic cell and module factory in France.
Designated a"Net Zero Strategic Project" by EU commission in 2026, this project is part of Europe’s drive toward reindustrialization and energy sovereignty to reduce dependence on non-European imports. On its 50-hectare site, HoloSolis has the space needed to expand the factory and adapt production equipment as technology evolves. This 950 Me project already secured more than 220Me in private and public funding.
Construction of the factory will begin in 2027 and beginning of production is planned for end of 2028. HoloSolis is supported by a global technology partnership with Trina Solar, a leader in the sector. This agreement provides access to a portfolio of key patents to introduce n-type TOPCon technology to Europe—one of the most efficient and mature technologies available today—while reducing industrial risk during ramp-up. At the same time, research teams will closely monitor the promising “tandem” technology, which combines silicon and perovskite. From an environmental standpoint, the plant exceeds regulatory standards with an exemplary commitment to resource efficiency, particularly regarding water management and consumption.
Ultimately, the plant will produce 5 GW of photovoltaic cells and modules per year, equivalent to nearly 10 million solar panels. This production will be sufficient to equip the equivalent of 1 million homes each year.
The establishment of HoloSolis represents a major economic boost for the french' Grand Est region, with the creation of 1,900 direct jobs. To support this growth, five regional working groups are already addressing needs related to the start of production, particularly housing, transportation, and training, including plans to create a center dedicated to Industry 5.0.
