AU Optronics PV Modules First Debut at Solar Power International 2009

HSINCHU, Taiwan, Oct. 26 /PRNewswire-Asia-FirstCall/ -- AU Optronics Corp.("AUO" or the "Company") (TAIEX: 2409; NYSE: AUO) will participate in SolarPower International 2009, scheduled to be held from Oct. 27 to Oct. 29 at theAnaheim Convention Center in California, U.S. The U.S. market is regarded as arapidly growing market for the solar PV (photovoltaics) industry, and AUOactively joins the exhibition by demonstrating its unique operating model andmono-crystalline and multi-crystalline PV modules with high module efficiency.

AUO will exhibit high-power output PV modules with a three bus-bars celldesign that can increase the efficiency of electricity storage and boost powerperformance. The AUO multi-crystalline PV module can reach an efficiency of385 watts, about 1.5 to 2 times higher than other related products in themarket. It is also the world's highest* power output PV module with a threebus-bars design that is compatible with mass production. It can fulfill thelarge 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-cellPV module that can be customized and designed for specific housing orcommercial building requirements.

As AUO acquired M. Setek, a major polysilicon and mono-crystal siliconwafer manufacturer in Japan, the company aims to offer "Total PV Solutions" bycooperating with partners throughout the value chain of energy business,including collaborating the projects with system houses. AUO will also exhibitthe full product lines and technologies of M. Setek, which have a qualitybuild 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 inthe solar photovoltaic industry. AUO has been proactively cooperating withsolar system providers at the end market.
