Trinasolar & HoloSolis Sign Patent Pact To Expedite Europe’s Solar Manufacturing Push

Trinasolar, a global smart photovoltaic (PV) and energy solutions provider, and French-based solar manufacturing company HoloSolis recently signed a patent licensing agreement, granting HoloSolis the right to use Trinasolar’s TOPCon (Tunnel Oxide Passivated Contact) solar cell technology. The deal comes at a time when the industry has been racked by IP disputes which have caused delays as well as costs on many firms across markets.

On this latest collaboration, Trinasolar said in a press release, “This agreement grants HoloSolis a license to practice Trinasolar’s globally recognized TOPCon patent portfolio in Europe, enabling the setup of a European production line based on mature PV technology. It marks a major step in accelerating Europe’s energy transition and strengthening its solar manufacturing capabilities.”

Using TOPCon Technology

TOPCon (Tunnel Oxide Passivated Contact) is a high-efficiency, industrially proven solar cell technology recognized for its scalability and performance. Its maturity and manufacturing readiness make it an ideal platform for rapid gigawatt-scale ramp-up — a critical advantage for new large-scale production facilities in Europe. 

Trinasolar further explained, its TOPCon IP portfolio includes some of the advanced and foundational patents in the field, which gives HoloSolis confidence in the robustness and scalability of the technology. Access to this portfolio will allow HoloSolis to produce at a large scale, low-carbon, high-efficiency PV panels in Europe. 

The company added, "The future HoloSolis factory in Hambach, Moselle, is designed to produce 10 million solar panels per year — a total of 5 GW annually — enough to power one million homes. The project is expected to generate over 2,000 direct jobs and bring major long-term industrial benefits to the Grand Est region."  

Partnership & Future Plans

"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.” 

"In just over a year, we have secured over €200 million in financing and achieved critical milestones, from permits and land acquisition to grid access and industrial design. We also received strong support from the market by receiving more than 20 GW of Letters of Intent for buying our production, enough to secure our first 5 years of production" said Bertrand Lecacheux, CEO of HoloSolis.  

Trina Solar adds "While today’s announcement focuses on the patent licensing agreement, the two companies are in active dialogue regarding future areas of collaboration, including potential strategic initiatives to further strengthen Europe’s solar value chain," it added.
