As the installation of solar electricity generation grows at an unprecedented pace world-widely and the performance of PV products gets improved steadily, the demand for PV modules of high quality and reliability that can operate in the harsh environment without rapid degradation has greatly increased.

SHANGHAI, Aug. 17, 2015 -- JA Solar Holdings Co., Ltd. (Nasdaq: JASO) (JA Solar), one of the world's largest manufacturers of high-performance solar power products, today announced that its standard 60-cell double-glass modules successfully passed all the reliability tests required by IEC61215 and IEC61730 standards and obtained at TUV SUD certifications, as well as the launch of mass production of the double-glass modules for global market.

Recently, as the installation of solar electricity generation grows at an unprecedented pace world-widely and the performance of PV products gets improved steadily, the demand for PV modules of high quality and reliability that can operate in the harsh environment without rapid degradation has greatly increased. To meet the demand, JA Solar has successfully completed the development of double-glass PV modules and started mass producing the modules from the beginning of August 2015. JA's standard 60-cell multi-Si modules are encapsulated using 2.5-mm thick high strength tempered glass on both sides with a frameless design. Compared to regular PV modules with glass only covering front side, the double-glass modules are proven to be much more reliable and endurable, as well as weather proof for deployment in the extreme environments of high-temperature, high-humidity, windy, salty, or arid conditions such as coastal fronts, fish farms, and deserts. Moreover, JA's double glass modules are designed based on IEC standard for 1500V system with a 30-year performance warranty, namely, of no greater than 2.5% power degradation in the first year followed by a linear annual degradation rate of 0.5%. At the end of this warranty, the performance level of such a double glass module will still be 85% of its initial rated power.

Mr. Jian Xie, JA Solar's Executive President, commented, "The successful pass of the IEC61215 and IEC61730 standard tests at TUV SUD and the start of mass production of the double glass modules for global market once again demonstrate the JA Solar's tradition of providing our customers high-performance PV products with high quality and reliability, as well as our commitment to meet the ever increased the worldwide demand for clean energy, through technological innovation and continuous performance improvement."
