HSINCHU, Taiwan, Oct. 26 /PRNewswire-Asia-FirstCall/ -- AU Optronics Corp. ("AUO" or the "Company") will participate in Solar Power International 2009, scheduled to be held from Oct. 27 to Oct. 29 at the Anaheim Convention Center in California, U.S. The U.S. market is regarded as a rapidly growing market for the solar PV (photovoltaics) industry, and AUO actively joins the exhibition by demonstrating its unique operating model and mono-crystalline and multi-crystalline PV modules with high module efficiency.

AUO will exhibit high-power output PV modules with a three bus-bars cell design that can increase the efficiency of electricity storage and boost power performance. The AUO multi-crystalline PV module can reach an efficiency of 385 watts, about 1.5 to 2 times higher than other related products in the market. It is also the world's highest* power output PV module with a three bus-bars design that is compatible with mass production. It can fulfill the large enterprise applications that American energy policy encourages, including electricity-generating needs for large power plants or solar farms. AUO will also showcase the stylish and environmentally friendly colored-cell PV module that can be customized and designed for specific housing or commercial building requirements.

As AUO acquired M. Setek, a major polysilicon and mono-crystal silicon wafer manufacturer in Japan, the company aims to offer "Total PV Solutions" by cooperating with partners throughout the value chain of energy business, including collaborating the projects with system houses. AUO will also exhibit the full product lines and technologies of M. Setek, which have a quality build and high conversion rates.

AUO restructured the "Energy Office" in October and formally founded its "Solar Photovoltaic Business Unit," aiming to show its rapid development in the solar photovoltaic industry. AUO has been proactively cooperating with solar system providers at the end market. By rapidly accumulating related experiences and technologies through the execution of large projects, the AUO solar photovoltaic team will attempt to build a good reputation and expand its worldwide business.

Apart from continually developing advanced green technologies in TFT-LCD industry, AUO has strengthened its presence in the green energy business. From saving energy to creating it, AUO hopes to establish its key position in solar energy by working to integrate systems with best-of-breed solar partners in end markets.
