First 210mm N-Type Monocrystalline Ingot Rolls Off Production Line at Trina Solar Qinghai Factory

Construction of the 20GW monocrystalline ingot Qiinghai project began on July 1 last year. Little more than eight months later the first monocrystalline furnace was ignited for calcination, on February 10, and was officially commissioned two days later. On the evening of February 17 the first monocrystalline ingot rolled off the production line, once again demonstrating Trina's ability to get important projects up and running in a very short time.

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 terms of 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.
