The certification utilized the cutting-edge Bankability 2 PfG 2940 testing standards, implementing a rigorous quality assessment for solar products. The tests were conducted following the IEC 63209-1:2021 standard, with several extensions and enhancements. The evaluation covered various aspects including Maximum Power Point Tracking (MPPT), performance testing, environmental adaptability testing, safety performance testing, and durability testing. Additionally, special attention was given to UVID and Letid tests, which are of particular interest to customers and financial institutions.
The test results showed that the loss rates of DMEGC’s modules under various conditions were significantly lower than the 5% standard set by IEC. Under all basic and extended test sequences such as TC, PID, DH, UV, DML, the degradation rates remained within 2%, passing the tests with flying colors.
By successfully passing the Bankability tests, DMEGC has effectively eliminated various adverse factors that could impact product performance, standing out in terms of safety and reliability. This provides a strong quality endorsement for distributors, buyers, end-users, and bank financing services worldwide. Notably, certification from TÜV Rheinland is highly recognized and influential in the European market, laying a solid foundation for consolidating and enhancing DMEGC’s competitiveness in this market.
