Quzhou, Aug. 2, 2024 - DAS Solar, a leader in N-type PV technology, holds the certification ceremony of "TÜV Rheinland Witness Laboratory" in Zhejiang, China.

With N-type technology at its core, DAS Solar has set the world record for conversion efficiency of large-area TOPCon cells for three consecutive times within eight months. The cell achieves an impressive mass production efficiency of up to 26.6%, and a open-circuit voltage of 742mV. At SNEC 2024, the Diamond series of DBC modules launched by DAS Solar won wide recognition in the industry for its outstanding performance in terms of power, safety and stability. In addition, DAS Solar and renowned institutions like the University of New South Wales carry out industry-university-research cooperation, in the guidance of the ‘one core and three branches’ strategy. Based on the most advanced TOPCon cell technology and three supporting technologies of the DBC, TSiP, and SFOS, DAS Solar aims to improve the cell efficiency to 40%.

The company sees the lab testing capability as the most crucial part, and invests heavily to improve the lab’s environment and the training of talents. Dr. Dengyuan Song, CTO of DAS Solar, says that after DAS Solar's PV lab qualified as a CNAS Laboratory, a TÜV SÜD TMP Laboratory, and a TÜV Nord CTF2 Laboratory, the accreditation of TÜV Rheinland Witness Laboratory further demonstrates the global recognition of DAS Solar's lab testing capability, management system, environment, personnel and hardware, indicating the excellent quality control and R&D strength.

At the certification ceremony, Weichun Li, Global Head of Power Electronics, General Manager of Greater China’s Solar & Commercial Products at TÜV Rheinland, mentions that overseas markets have more demanding standards and requirements for the safety, performance and reliability of import products. As a leading inspection and certification institute in the industry, TÜV Rheinland will do its utmost to evaluate the performance parameters of the products, ensuring the stable operation throughout their life cycle. In the future, TÜV Rheinland will facilitate a good reputation of DAS Solar in global markets and enhance the company’s brand competitiveness.

Yong Liu, Chairman and President of DAS Solar, emphasizes that as a first-tier brand in the PV industry, the company always puts the quality improvement in the first place to provide customers with optimal product value. “We’ve invested a large number of senior personnel and professional equipment in the lab construction for rigorous product testings which can ensure the high standard and quality of each module. The TUV Rheinland Witness Laboratory qualification is a testament to our lab testing and management capabilities. I’m convinced that through close cooperation and communication between both parties, we’ll be able to further improve the quality control capability, optimize the product testing cycle, and realized the Dual Carbon Goals.

DAS Solar photovoltaic lab is one of the most advanced enterprise labs in the industry, integrating R&D and quality control with professional and comprehensive testing equipment, covering dozens of tests including module appearance inspection, maximum power determination, insulation test, wet leakage current test, PID, hail, LID, UV, wet freezing and damp heat test. Looking to the future, DAS Solar will continue to strengthen the testing capability and in accordance with strict standards, striving to upgrade the module competitiveness and provide customers with reliable products and better services.
