Quality focus starts from product inception

The engineering team places a major emphasis on both process and equipment capabilities. Every material going into the product is heavily tested during the product design to ensure the highest quality standard and level of reliability.

Quality control throughout the whole value chain

Trina Solar ensures the highest quality standards for our PV products across the entire supply chain. This mitigates risks and increases return on investment. Because of our dedication to delivering high-quality PV products, Bloomberg New Energy Finance (BNEF) named Trina Solar as the “most bankable” global PV manufacturer in 2016. One-hundred percent of respondents to the BNEF survey said Trina Solar’s modules were the most bankable, which contributed to our leading position in the global solar PV market. This is a high honor and a strong endorsement for our product quality.

Internal product verification tests are stricter than IEC/UL requirements

With over 36 in-house tests and a state of the art research and development lab, Trina goes beyond requirements to deliver the highest quality product to customers. From one end of the supply chain to the other, customers can trust the quality and reliability of Trina.

Having a method for assessing a PV system's reliability and safety is vital to Trina

As part of its commitment to quality and reliability in its own products and across the solar industry, Trina Solar has partnered with third-party testing groups, including TUV Rheinland Group, China General Certification Centre and UL. In 2012, Trina Solar became the first solar PV company to obtain UL's Client Test Data Program certification after undergoing a rigorous inspection and audit process.
