JinkoSolar has become the first Chinese manufacturer of PV modules to earn Qualification Plus (“Q+”) certification from TÜV Rheinland.

Q+ certification is the most recent upgraded test certification introduced by TÜV Rheinland and is recommended by the California Energy Commission.

The standard includes performance tests in regions where temperatures fluctuate in a wide range. Dynamic load tests ensure the modules remain resistant to cracking under wind vibration circumstances. Other tests in the Q+ standard include humidity and freeze circulation tests, insulation tests and hot-spot testing.

“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,” 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.”
