Q+ certification is the most recent upgraded test certification introduced by TUV Rheinland and 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.

Q+ certification utilizes stringent criteria compared to IEC 61215, which currently serves as the industry standard to reflect the operational reliability of modules under extremely harsh climatic conditions. It includes actual performance tests in regions where temperatures fluctuate greatly such as dessert. Dynamic load tests that are not included in IEC 61215 standard to ensure the modules remain resistant to cracking under outdoor wind pressure vibration circumstances, which better reflect the mechanical strength of the module in real condition, humidity & freeze circulation tests, insulation tests and hot-spot test, etc.

"Q+ certification’s stringent testing criteria represent the industry’s latest standards. I’m very pleased that JinkoSolar is the first Chinese PV manufacturer to get this certification," commented Mr. Kangping Chen, Chief Executive Officer of JinkoSolar. "We have always focused on providing our clients with the highest quality and reliable products that can guarantee a return on their investment."
