Quality focus starts from product inception

Quality control throughout the whole value chain

As a vertically integrated company, Trina Solar ensures the highest standards of quality for our PV systems across the entire supply chain, to mitigate risk and increase your return on investment. Ranked as one of the world’s most bankable solar manufacturers by Bloomberg New Energy Finance, Trina Solar has the staying power and dependability to stand behind our products for decades.

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.
