JA Solar Holdings Co. Ltd. says its entire portfolio of solar PV modules has passed the 96-hour potential induced degradation (PID) resistance test under the conditions of 85 degrees C and 85% relative humidity (double 85) at -1,000 V of system voltage bias as required to meet the IEC62804 standard.
In addition, as reported earlier, JA Solar’s multi-crystalline Si RIECIUM modules passed an extended 500-hour PID test conducted by TUV SUD with a degradation of less than 2%. The company says this result is a testament to the anti-PID capability of the modules, which are now guaranteed to be able to sustain a doubled (192 hours) IEC62804 standard PID test and are certified by PI-BERLIN and PVEL. The anti-PID performance provides assurance for stable operation of PV installations, especially for those operating in a hot and humid environment over their 25-year life span, according to JA Solar.
“The advantage of JA’s solar products is reflected not only in its core technology that features high performance and cost-effectiveness, but also in its reliability,” says Dr. Wei Shan, chief technology officer of JA Solar. “To be able to pass ‘double 85’ anti-PID certifications for all our PV modules in mass production is a tremendous achievement in terms of JA Solar’s ability to produce high-performance and highly reliable PV modules to meet the ever-growing demands for better solar products from our customers and project partners.”
