(Photo: http://photos.prnewswire.com/prnh/20130211/594514 ) The PID-resistance test, certified by the Solar Energy Research Institute of Singapore (SERIS), subjected the solar panels to some of the harshest PID-test conditions in the industry:
Negative voltage of 1,000 Volts
Ambient temperature of 60°C
Relative humidity of 85 percent
Test period of 96 hours
The REC Peak Energy solar panels performed very well in the test, showing less than two percent power degradation and demonstrating high quality and reliability. Thanks to optimization of design, materials selection and in-house manufacturing processes, REC has succeeded in further improving its solar panels' durability and reliability for the harshest environments. REC's solar panels are already certified to the industry-accepted TÜV Rheinland standards, in which a negative voltage of 1,000 Volts is applied to the panels at 25°C for a period of 168 hours. "We are very proud to be one of only a few manufacturers passing the PID test at this protocol and doing so with such excellent results," commented Luc Graré, Senior Vice President Solar Sales and Marketing, REC. "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." The last PID certification further confirms REC's commitment to produce reliable solar panels with outstanding performance even when exposed to the harshest conditions and environments. It is also proof of REC's low degradation levels and provides a quantitative and independent assessment of reliability performed by a neutral and credible third party institute. This certification ensures that REC offers customers, developers, banks and investors all over the world, solar panels that perform in accordance to REC's warranty in the most demanding of climates.
