JA Solar, a global manufacturer of high-performance solar power products, announced that the performance of the company’s solar modules in extreme environments has been certified by the China Quality Certification Center (CQC), China’s largest professional certification body.
JA Solar is the first solar product manufacturer to receive this CQC accreditation.
As part of the certification process, JA Solar 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 JA Solar’s modules performedwell in each of these environmental conditions.
The CQC certification is the latest quality accreditation awarded to JA Solar. The company’s products have received numerous quality certifications, having passed TÜV SÜD’s Thresher tests, TÜV NORD’s salt-mist and sulfur-dioxide corrosion tests, ammonia corrosion tests, and dust and sand corrosion tests, among others.
Hot, dry climates have features such as dryness and large temperature difference. Areas characterized by this climate include northwestern and northern China, deserts in the Middle East and North Africa, southwestern United States and northwestern India. Deserts under this climate condition are also affected by dust and sand.
Warm-wet climates have features such as both high temperature and high humidity. Areas characterized by this climate include southern coastal areas of China, Southeast Asia and tropical forest in the Caribbean region. Under the climate condition, coastal regions and areas near saline lake are affected by salt fog as well. Plateau climate has features such as high altitude, long-term low temperature and frozen soil. Areas characterized by this climate include Qinghai-Tibet Plateau, Gansu Province and Qinghai Province. These three harsh climate conditions negatively impact modules’ reliability, life-span and performance.
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.
