Recently, Haitai Solar’s PV modules successfully passed the North German TÜV DH3000 performance test, demonstrating outstanding reliability under rigorous testing conditions.

The DH3000 test is three times more stringent than the IEC standard, with modules exposed to a constant temperature of 85°C and relative humidity of 85% throughout the test. Haitai Solar’s 630W and 635W module variants underwent prolonged exposure to high temperature and humidity, followed by a series of evaluations, including visual inspection, maximum power output, insulation performance, and wet leakage current. The results showed that the modules maintained their appearance and key performance characteristics, with power degradation well below the limit specified by the IEC standard. These results further demonstrate the strength of Haitai Solar’s module encapsulation design and manufacturing processes.
Looking ahead, Haitai Solar will continue to strengthen its core business, accelerate technological development and the commercialization of innovations, and bring more high-quality products to markets worldwide.
