China Sunergy Modules Pass TUV "PID" Test

NANJING, China, Sept. 27, 2012 /PRNewswire/ -- China Sunergy Co., Ltd. (Nasdaq: CSUN) ("China Sunergy" or the "Company"), a specialized solar cell and module manufacturer, today announced that its solar modules passed the potential induced degradation test ("PID test") conducted by TUV Rheinland Group, an internationally recognized certification authority which provides neutral test reports and certificates to a wide range of products and services.

The PID test was conducted to assess loss of power output of solar modules under severe conditions of high voltage, high temperature and high humidity. In the recent years, the continuous degradation of solar modules, especially those exposed to humidity, has been one of the largest concerns of solar project owners. Thus, anti-PID performance has become one of the most important factors for solar module buyers in making purchasing decisions.

Under the PID test conditions, China Sunergy's modules are exposed to 1,000 volts of bias voltage for 96 hours at a temperature of 60 degrees Celsius and relative humidity of 85%. In order to pass this extreme test, the maximum degradation of power output between initial and final measurement should not exceed 5%, while the test result of China Sunergy's modules is only 0.1%, well beyond this standard.

Mr. Stephen Cai, CEO of China Sunergy commented, "We are happy to get passed with such superior results. The PID test is an important indicator to prove the quality and reliability of our modules. China Sunergy has also achieved a number of certifications over the years, which attests to our outstanding product quality and continuous improvement in product performance. We are not just focusing on efficiency, but also on safety and quality. We believe these are the main reasons why customers are loyal to us and why we have been able to expand into new markets despite the current challenging market conditions."
