The Solar Energy Research Institute of Singapore (SERIS) has certified Renewable Energy Corporation’s (REC) modules for potential-induced degradation (PID) resistance.
SERIS tested REC modules at higher temperatures and relative humidity levels than previously tested and certified at TUV Rheinland. REC said that under the enhanced PID testing regime at SERIS, the modules experienced less than 2% power degradation.
SERIS used negative voltage of 1,000 Volts then exposed the modules to an ambient temperature of 60 degrees C with a relative humidity of 85%, tested for 96 hours.
At TUV Rheinland, modules were exposed to a negative voltage of 1,000 Volts in 25 degree C temperatures for a period of 168 hours.
Luc Grare, Senior Vice President Solar Sales and Marketing, REC said, "Consistent high yield, quality, and durability are of utmost importance in today's market and our outstanding performance in this demanding test clearly demonstrates that REC solar panels are among the best in the industry."
REC told PV-Tech that the modules certified by SERIS were now in production and would be initially supplied to the APAC and US regions.
