JA Solar’s polycrystalline Riecium module has passed TUV SUD’s 500-hour potential induced degradation (PID) test.
The tests involve exposing the panels to extreme conditions including 85˚C, 85% humidity and 1000V of system voltage bias. The panels showed less than 2% power degradation.
The company had previously stated that the modules could pass the double standard IEC62804 PID, which involves the same conditions, but for a duration of only 92 hours.
“By passing the 500-hour PID Test with our Riecium modules, JA Solar has reached yet another milestone in terms of our ability to produce highly reliable solar products,” said Yong Liu, COO, JA Solar. “This new test result is a further testament to JA Solar's unrivalled efforts to push the boundaries of PV technology, and deliver significant value to our customers through our product's superior reliability.”
The average conversion efficiency of Riecium modules currently in production has surpassed 18.6%, while power output has reached 270W, 10W higher than the industry average, according to JA Solar.
