The entire range of JinkoSolar solar modules has passed the salt mist corrosion test in accordance with International Electrotechnical Commission (IEC)61701 standards, the Chinese company announced today.
"The satisfactory salt corrosion test results confirm that JinkoSolar's modules can be installed in any coastal regions and run without interference," said Kangping Chen, CEO of JinkoSolar.
Resistance to salt mist corrosion is key to ensuring adequate solar power yield in coastal regions where salt-laden humidity and rain persist. These salty conditions adversely affect key module components, such as frames, junction boxes and glass surfaces, thereby reducing performance and shortening module lifetime.
The salt mist corrosion test was conducted by international research firm TUV Rheinland. To replicate real-world, harsh conditions, JinkoSolar's modules underwent 56 days of eight test cycles. Each module was sprayed with salt water for two hours and then stored at 40 degrees Celsius and 93 percent humidity for 20 hours.
In March, JinkoSolar's modules successfully passed TUV Rheinland ammonia corrosion tests, a key indicator of resistance to degradation in agricultural areas such as livestock farms. Additionally, the company's solar modules consistently achieved the highest unit power yield in PHOTON Laboratory's outdoor field tests.
