Trina Solar's State Key Laboratory Testing Center has become the first testing center in the solar industry to receive the Power Measurement Uncertainty Assessment Service (UAS) Certificate from German testing and certification company TÜV Rheinland.
The certificate validates the accuracy of on-site power measurements recorded at the Trina testing center. Following the certification, all products assessed by the center will carry a TÜV Rheinland certification mark.
Trina said it received the TÜV Rheinland certificate after seven months of continuous tracking, identifying key influencing factors, technique optimization and rigorous on-site training.
"This certification proves that the procedures, test equipment and staff capabilities employed during the process of power output measurement at Trina Solar's State Key Laboratory Testing Center are in accordance with stringent International Electrotechnical Commission (IEC) standard as well as TÜV Rheinland strict assessment criteria," the company said.
The company added that the certification provided "clear guidance to PV manufacturers and buyers on the power rating of PV modules, provides transparent information about the performance and minimize measurement uncertainty of PV module output. It also helps manufacturers improve the accuracy of measurements and reduce measurement errors."
Wei Zhou, vice president of Trina's Quality Department, said, "The PV industry is facing fierce competition. Modules verified by an objective third party greatly enhance customer confidence and increase sales. With the continuing development of solar power in China, ensuring the quality of solar power plants is paramount. TÜV Rheinland's recognition of our internal power measurement system assures our partners and customers of the reliability and quality of our modules."
Robert Struwe, vice president of TÜV Rheinland Greater China Solar/Fuelcell Technology Division, added that the group's power measurement system was not "a simple certification assessment but rather a continuous process of improvement and optimization."
