Trina Solar’s Yiwu factory was assessed by TiGroup, a certification body specialising in health, safety, environmental and sustainability inspection and testing, and received official certification at the First China Carbon Finance Forum. A range of indicators were evaluated on-site, including:

Energy and resource utilisations

Greenhouse gas reduction implementation

Carbon offset implementation

Intelligent information management systems for energy and carbon emissions


Product design

Compliance requirements

Management requirements

The factory achieved an overall score of 79.68 out of 80 for 2022, and successfully obtained the Zero Carbon Factory (Type 1) Certificate, which is recognised by the China Energy Conservation Association. Trina Solar is also able to reveal that the carbon emissions per unit output of the Yiwu site decreased by 21.77 percent in 2022 compared to 2021, while the power consumption per unit product decreased by 9.51 percent. This is thanks to its comprehensive, sustainable supply chain that includes product design, energy management and intelligent system optimisation.

Trina Solar’s Yiwu factory is a Vertex Super Factory, and the primary manufacturing facility for the production of Trina’s Vertex S product line. As a Vertex Super Factory, the site is newly built and fully automated, with state-of-the-art facilities to produce Vertex S modules.

The Vertex S series of solar panels was designed with European rooftops in mind, including residential, commercial, and industrial application. Vertex S achieves higher efficiency and power thanks to the use of 210mm silicon wafers and is compatible with mainstream inverters and mounting systems. The module series supports Trina Solar’s mission of bringing cleaner, greener energy solutions to everyone.

“It’s a groundbreaking achievement to operate the first factory in the industry to be recognised as a zero-carbon facility” said Gonzalo de la Viña, President EMEA at Trina Solar. “This certification demonstrates Trina Solar’s strong commitment to sustainable development and zero carbon practices across our technology, products, and process management. Our Vertex S solar panels are extremely popular in Europe, so we’re pleased to be able to offer the first products in the industry that are not only sustainable themselves, but have been manufactured in a zero carbon factory, reducing our customers’ carbon footprint at every step. We look forward to continuing our sustainable manufacturing at our Yiwu site while discovering new and innovative ways to further improve and enhance the entire Trina Solar ecosystem to reduce emissions, protect our environment and improve communities across the globe with low-carbon, green technology.”

In 2022, Trina Solar was also recognised for its industry-leading low carbon emissions in the manufacturing process of its full range of 210mm Vertex modules. The modules were awarded a Life Cycle Assessment (LCA) certificate by TÜV Rhineland in Germany, becoming the first 210mm modules in the industry to do so.
