In mid-February, the first 210mm n-type monocrystalline ingot rolled off the production line at Trina Solar’s Qinghai Factory, marking significant progress in the factory’s Phase I. The factory aims to be the first zero-carbon park in its region.

The first 210mm n-type monocrystalline ingot rolled off the production line at Trina Solar’s Factory

Construction of the 20GW monocrystalline ingot project began on July 1, 2022. By Feb. 10, 2023, the first monocrystalline furnace was ignited for calcination and was officially commissioned two days later. On the evening of Feb. 17, the first monocrystalline ingot rolled off the production line, once again demonstrating Trina’s ability to get important projects up and running quickly.

The 210mm n-type monocrystalline ingots are mainly used to ensure the production capacity and quality of Trina Solar’s n-type modules. The 210mm n-type monocrystalline ingot coming off the production line is 3800mm long and weighs 542kg, which is at the world’s leading level in production technology, quality, and scale.

Trina Solar has always maintained high standards and rigorous requirements in manufacturing. The number of particles of size 0.5 µm or larger per cubic meter of air in the monocrystalline silicon workshop is less than 100,000, and the number of particles of size 0.5 µm or larger per cubic meter of air in materials preparation areas is less than 10,000, well above industry standards.

As this factory covers almost the entire PV manufacturing chain, it will become one of Trina Solar’s main factories for ensuring the supply of primary materials for Trina Solar’s 210mm n-type modules. It will also create greater value for customers in the n-type era. Recently upgraded, the “Ace Mix” of Vertex n-type modules of 605W and 695W can be used in a wide range of complex settings, such as mountainous terrain, water surfaces, and deserts. Trina Solar’s n-type full-scenario solutions will help users obtain great benefits in many settings.

Trina Solar is committed to building the first Zero-Carbon Industrial Park featuring Source-Grid-Load-Storage integrated operation in its region based on green and low-carbon development. This means the operation includes almost all key processes of the energy network, including the energy source, grid, and storage. The company will integrate its technological and industrial advantages with local advantages in resources and location, and it anticipates integrating zero-carbon solar energy and energy storage and building a stable and environmentally friendly zero-carbon energy system.
