Bangalore, May 2014 -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, the world leader in product safety testing and certification, 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 V
• Relative humidity of 85%
• Test period of 96 hours
• Results showed less than 1% degradation in the modules, while the accepted level is between 4 and 5%.

The strong performance of Tata Power Solar's modules under such extreme conditions showcases the superior quality and reliability of its products.

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 500 MW of modules world-wide over last 25 years. This latest PID-free certification from UL is a testament to our commitment to producing high-quality solar modules that set the standard as best in the world."

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."
