SHANGHAI, China, March 6, 2013 (GLOBE NEWSWIRE) -- JA Solar Holdings Co., Ltd. (Nasdaq:JASO) ("JA Solar" or the "Company"), one of the world's largest manufacturers of high-performance solar power products, today announced that the Company's entire range of modules has received UL 1703 certification for use on 1000 Vdc systems in the United States and Canada from Underwriters Laboratories ("UL"), a global independent safety science company. The modules were tested in Intertek laboratories and also received ETL certification, demonstrating their compliance with the requirements of widely accepted product safety standards.

In addition to higher voltages, 1000 Vdc systems are associated with lower installation costs, increased inverter efficiency, and a reduced need for balance of system (BOS) components. The use of such systems is becoming increasingly common in several solar markets, particularly the United States, where JA Solar has already supplied modules to several 1000 Vdc projects. The Solar Energy Industries Association estimates the 1000 Vdc systems market in the U.S. will grow at a compound annual rate of 25% between 2011 and 2016.

"UL certification is proof of the suitability of JA Solar modules for a wide range of solar installations," said Mr. Yong Liu, CTO of JA Solar. "There is a growing demand for modules which allow for longer installation runs, not just in North America, but across the global solar market, and this certification puts JA Solar in a strong position to service that need."
