JinkoSolar becomes first Chinese manufacturer to receive Q+ certification


JinkoSolar has become the first Chinese PV manufacturer to receive German certification organization TÜV Rheinland’s Qualification Plus (Q+) certification.

Q+ certification is the most recent upgraded test certification introduced by TÜV Rheinland. It is now recommended by the California Energy Commission, which implies that it could become a requirement for entering California’s renewable energy market in the future, JinkoSolar noted.

Q+ certification utilizes more stringent criteria than IEC 61215, which currently serves as the industry standard, to reflect the operational reliability of modules under extremely harsh climatic conditions.

The certification testing criteria includes actual performance tests in regions where temperatures fluctuate greatly, such as in deserts. It also includes dynamic load tests that are not included in the IEC 61215 standard to ensure modules remain resistant to cracking under outdoor wind pressure vibration circumstances. The certification, which also includes humidity and freeze circulation, insulation and hot-spot tests, better reflect the mechanical strength of the module under real conditions, the company said.

"Q+ certification’s stringent testing criteria represent the industry’s latest standards,” said JinkoSolar CEO Kangping Chen. “We have always focused on providing our clients with the highest quality and reliable products that can guarantee a return on their investment."
