“This accomplishment reflects our leadership in TOPCon innovation and underscores our commitment to empowering our customers with high-performance, reliable solar solutions,” said Ni Lili, President of Solar Product Division at Trinasolar.

Trinasolar’s high-efficiency Vertex N TOPCon Ultra modules deliver increased power output, with large-format modules (LFMs) reaching up to 740W in mass production this year, unlocking greater value for customers. Their superior bifaciality and excellent low-irradiance performance translate into higher system efficiency and more stable energy yield across diverse scenarios.

As an early mover of n-type technology, Trinasolar has been at the forefront of industrializing TOPCon since beginning research in 2015. The company has set numerous records in cell efficiency and module power, achieving remarkable breakthroughs in the field. In August 2023, Trinasolar became the first module manufacturer to achieve mass production of TOPCon modules with power exceeding 700W, pushing module power to a new level.

Trinasolar remains steadfast in advancing TOPCon technologies, having filed more than 700 patents as of October 2025. It has also signed a patent licensing agreement with HoloSolis, granting the right to use Trinasolar’s TOPCon solar cell technology in Europe—a move that highlights how global innovation can strengthen local industry.
