Chint/Astronergy announced that its mono- and polycrystalline modules have passed the Potential Induced Degradation (PID) test conducted by TUV Rheinland. The test results illustrated the good performance and high reliability of Astronergy PV modules.
PID is an effect that leads to significant power output decline of PV modules under the condition of negative bias voltage, high temperature and increased humidity. It has become an increasing concern in the solar industry because of the negative impacts.
In the test, PV modules from Astronergy were assessed after being exposed in the -1000 voltage condition with the temperature 85°C as well as relative humidity 85% for 96 hours. Astronergy PV modules have achieved a less than 1.4% degradation result, which is well below the TUV standard of not exceeding 5% under such restricting requirements.
“The superior quality of our PV modules is a key factor to protect the investment in PV systems. Gaining the positive results also marks the great efforts we have put into the whole manufacturing process. ” Astronergy Vice President Dr. Chuan Lu commented.
