JA Solar, a manufacturer of high-performance solar power products, today 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 the Company's modules continued to perform well 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 corrosion and sulfur dioxide corrosion tests, ammonia corrosion tests, and dust and sand corrosion tests, among others.

"We're delighted to be the first solar manufacturer to pass this stringent testing, which is a further testament to the superior durability of JA Solar modules and the capabilities of our R&D team," said Mr. Yong Liu, JA Solar's chief operating officer. "This certification gives our customers further confidence that JA Solar modules will deliver reliable performance, even in extreme environmental conditions."
