Trinasolar and French solar manufacturer HoloSolis have signed a patent licensing agreement allowing HoloSolis to use Trinasolar’s Tunnel Oxide Passivated Contact (TOPCon) solar cell technology in Europe.
The agreement gives HoloSolis access to Trinasolar’s patent portfolio, which is widely recognised in the PV sector, and will support the establishment of a European production line for high-efficiency solar panels.
“This partnership with Trinasolar allows us to combine world-class technology with European manufacturing leadership,” said Oliver Schultz-Wittmann, CTO of HoloSolis.
“By obtaining this license, we ensure that our products are both innovative and aligned with global IP standards, offering reliable, high-performance solar solutions made in Europe.”
The planned HoloSolis factory in Hambach, Moselle, is designed to produce 10 million solar panels annually – equivalent to 5GW of capacity, enough to power one million homes.
The facility is expected to create over 2,000 direct jobs and deliver long-term industrial benefits to the Grand Est region.
Trinasolar said its TOPCon portfolio includes “some of the most advanced and foundational patents in the field,” which will enable large-scale, low-carbon panel production in Europe.
Gonzalo de la Viña, President Europe at Trinasolar, said: “This agreement is more than a license – it’s a symbol of how global innovation can fuel local industrial strength.
“By bringing proven, high-efficiency technology to HoloSolis, Trinasolar is contributing to the development of a stronger and more resilient PV manufacturing ecosystem in Europe.”
HoloSolis said it has secured more than €200m in financing and received over 20GW of Letters of Intent from buyers, covering its first five years of production.
“In just over a year, we have secured over €200m in financing and achieved critical milestones, from permits and land acquisition to grid access and industrial design,” said Bertrand Lecacheux, CEO of HoloSolis.
“The partnership with Trinasolar is a strong vote of confidence in our vision to become a European industrial champion in solar, rooted in the region and aligned with European values.”
