Changshu, China October 10, Zhongli Talesun Solar Co., Ltd ( “Zhongli Talesun” or “Talesun”), the first Chinese solar company awarded the “Quality Tested Certificate” by VDE, recently announced that its photovoltaic modules series have successfully passed the salt mist, ammonia corrosion test and the PID test at 85 degrees Celsius by TUV Rheinland. It makes Talesun one of the few module manufacturers who have passed these tests carried out by TUV Rheinland.


The salt mist corrosion test under IEC61701 level 6 and the ammonia corrosion test according to IEC62716 ED 1 Draft B were conducted by TUV Rheinland on the modules sent by Talesun. All test samples fulfill the standard requirements with respect to the power output, grounding continuity, wet leakage current, insulation resistance, etc. The test results demonstrate that Talesun’s modules could be installed safely and will maintain performance even in special areas, such as coastal lands with high saline environment and farming areas.


Additionally, Talesun also passed the PID (Potential Induced Degradation) test by TUV Rheinland for which the modules were exposed in 1000V of bias voltage under the condition of 85C/85% relative humidity for 96 hours, the most severe condition for the PID test. PID is a phenomenon caused by high voltage potential, which may induce power degradation and lower performance of PV modules, causing over 50% degradation of output power in worst case. The issue has been increasingly in concern by buyers and module manufacturers in the field. The test results from TUV Rheinland is a step-up from another PID test Talesun passed under a relatively less several condition for which the modules were exposed in 1000V of bias voltage under the condition of normal air temperature for 96 hours. The excellent performance of Talesun modules was recognized and appreciated by engineers from TUV Rheinland.


David Chen, Vice President of Zhongli Talesun, stated that “The tests prove Talesun modules’ excellent performance and reliability. Guided by the developing principle “quality oriented, look ahead”, Talesun will keep this advantage and continue to provide our clients with products with premium quality.”
