World-Class Manufacturing

State-of-the-art manufacturing lies at the core of Suntech's business and enables us to deliver high-quality solar products to our customers at an affordable price. Our 2-Gigawatt manufacturing capacity makes Suntech the largest module manufacturer in the world, allowing us to offer advanced products and leverage economies of scale. Suntech manufacturing sites, located in China, Japan and the United States, follow the strictest production guidelines and are staffed by highly-trained manufacturing experts.



Suntech solar cells undergo a chemical surface micro-texturing process that improves their ability to capture light. The cell production facility employs industry-leading manufacturing techniques to create high conversion efficiency solar cells.



Cells with similar electrical characteristics are matched during module assembly to minimize efficiency losses.  Laminated modules are equipped with corrosion-resistant frames and weather-proof electrical components to create a durable, water-tight product. 



Our quality control program features 52 tests and checks throughout the cell and module manufacturing process. Once fully assembled, all Suntech modules undergo a final performance test and are categorized based on power and current production. Our rigorous review process ensures we deliver only the highest quality products to our customers.
