Tata Power Solar, one of the largest solar manufacturers in the country, recently announced that its crystalline PV modules have successfully passed the Potential Induced Degradation test conducted by Underwriters Laboratories, a premier global independent safety science company.
The PID test assesses solar modules’ susceptibility or resistance to power losses due to high voltages, temperatures and humidity.
UL, a 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. The conditions included temperature of 85 ± 5°C, negative voltage of 1,000 Volts, relative humidity of 85 percent and test period of 96 hours.
Results showed less than 1 percent degradation in the modules, while the accepted level is between 4 and 5 percent.
The company said the strong performance of the modules under such extreme conditions reflected the superior quality and reliability of its products.
“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,” said Ajay Goel, CEO of Tata Power Solar.
Tata Power Solar operates three manufacturing units in Bangalore with a production capacity of 200 MW of module and 180 MW of active cell. It has completed more than 93.65 MW of ground-mount utility scale and 14.22 MW of rooftop and distributed generation projects across the country as of FY13. It also offers a diverse line of solar products for both urban and rural markets which include water heaters, home lighting, street lighting, power packs and water pumps among others.
