According to reports, Tata Power Solar, one of the largest solar manufacturers in India, today announced that its crystalline PV modules have successfully passed the Potential Induced Degradation (PID) test conducted by Underwriters Laboratories (UL), a premier global independent safety science company.
UL subjected Tata Power Solar’s PV modules to some of the harshest PID-test conditions in the industry:
- Temperature of 85 ± 5°C
- Negative voltage of 1000 Volts
- Relative humidity of 85pc
- Test period of 96 hours
Results showed less than 1 pc degradation in the modules, while the accepted level is between 4 and 5pc.
Commenting on the certification, Ajay Goel, CEO, Tata Power Solar said, “As one of the oldest solar manufacturers in the world, we have exported more than 500MW of modules world-wide over last 25 years.”
Suresh Sugavanam, managing Director, UL India said, “Our test program evaluates the modules’ performance against system voltage stress, verify module safety and screen for PID susceptibility. Tata Power Solar’s modules have produced excellent results proving that they are not susceptible to PID thereby classifying them as among the best in the solar industry.”
