JA Solar Holdings Co., Ltd. is the first to have its solar modules certified by the China Quality Certification Center (CQC), China’s largest professional certification body.
The modules were tested for reliability and durability under high temperatures in both dry and humid conditions, as well as in conditions simulating those found at high altitudes. The tests, which meet and in some cases exceed International Electrotechnical Commission standards, concluded that the company’s modules continued to perform well in each of these environmental conditions.
Existing testing standards do not adequately evaluate the modules’ performance under these extreme environment conditions. Having supervised the establishment of a large number of power plants as well as analyzed test data, CQC summarized the influences that regional climates can have on modules and designed testing methods to fairly evaluate the performance of the solar modules in extreme environments. These three tests include 30 subtests in extreme environments such as salt spray test, ammonia test, and PID test.
