TÜV SÜD, as the world leading third-party testing and certification organization, has awarded DAS Solar’s PV laboratory TMP accreditation. DAS Solar's PV laboratory had obtained CNAS laboratory accreditation and TÜV Nord's CTF witness laboratory qualification previously.

The TMP accreditation from TÜV SÜD further enhances DAS Solar's industry-leading advantage in product quality. TMP is a certification allowing a manufacturer’s own laboratory resources to test products produced by the company itself, in accordance with the requirements of the certification standard. Mr. Xu Hailiang, Vice President of TÜV SÜD, stated, "TÜV SÜD's award of TMP accreditation to DAS Solar's PV laboratory signifies DAS Solar utilizes its own testing equipment and resources, with the assistance of TÜV SÜD experts, to conduct on-site testing in accordance with standard requirements. DAS Solar efficiently manages the testing progress, obtains test data analysis promptly, and effectively reduces the testing period for new products with TMP accreditation. This not only leads to cost savings but also enables swift response to market changes and enhances product quality."

Mr. Liu Yong, the Chairman and President of DAS Solar stated, "DAS Solar has always placed a high value on product quality and invested heavily in senior personnel and specialized equipment for the lab's construction. The TÜV SÜD designation of TMP accreditation highlights the laboratory's proficiency in testing and management."

DAS Solar's N-type TOPCon 3.0 Plus cells achieve an average conversion efficiency exceeding 25.6% in mass production. The laboratory efficiency has surpassed 26.24%, setting a new world record with an open-circuit voltage of 730mV. The N-type module's peak power reach 640W, while its conversion efficiency reaches a high level of 22.9%. The technical roadmap for the future TOPCon4.0, TBC, SCPC, TSiX, and finally SFOS in collaboration with the University of New South Wales (UNSW) to exceed 35% cell efficiency." said Dr. Song Dengyuan, CTO of DAS Solar. "The acquisition of the TÜV SÜD TMP laboratory accreditation proves that DAS Solar has reached a high level in talents, quality control, facilities, technology research and has become one of the industry's leading manufacturing enterprises."

DAS Solar's PV laboratory encompasses a sprawling area of approximately 1000 square meters. This laboratory boasts a team of skilled professionals numbering in the dozens and is equipped with cutting-edge and comprehensive testing equipment. It covers a wide array of testing projects, ranging from meticulous visual inspections of modules to the determination of maximum power, insulation testing, wet leakage current testing, PID analysis, hail resistance evaluations, LID assessments, UV testing, as well as damp heat, freeze-thaw, and other rigorous examinations.

From the beginning of PV laboratory establishment, DAS Solar has consistently placed product quality at the forefront of its mission. DAS Solar has seamlessly integrated state-of-the-art testing capabilities into the production and delivery of its modules. The TMP accreditation is a strong validation of the product quality control and laboratory testing capabilities in DAS Solar, highlighting its exceptional testing proficiency and management excellence.
