Suntech Displays Leading Solar Products at Inter Solar 2007 Germany

First Quarter Results Highlight Strong Sales Growth in Europe
(PresseBox) (Wuxi, Jiangsu Province, ) Suntech Power Holdings Co., Ltd. (NYSE: STP), one of the world's leading manufacturers of photovoltaic (PV) cells and modules, today announced it will be participating at Inter Solar 2007 in Germany. At the event, Suntech will display its premium quality and high-efficiency solar PV products including monocrystalline and polycrystalline PV modules with outputs ranging from [170Wp to 280Wp], as well as [MSK's] leading building integrated PV solutions for roof and glazing applications.

Suntech also recently announced their first quarter 2007 earnings. The results far exceeded revenue expectations with total net revenues growing 174.5% year-over-year to $246.7 million, and total production output growing 138.2% year-over-year to 64.7MW.

In its key sales geographies, Suntech's sales continue to outpace market growth. In particular, sales volumes have grown measurably in Spain, where the Company shipped 27MW in the first quarter of 2007, similar to shipment volumes in Germany. Commenting on the first quarter results, Dr. Zhengrong Shi, Suntech's Chairman and CEO, said, "We experienced exceptionally strong demand for our PV modules due to high customer satisfaction and a strong reputation for reliably delivering large volumes of superior quality and performance products on schedule. The demand for our products has never been stronger."

Suntech Your Essential Solar Partner

Suntech's ability to rapidly expand production capacity whilst maintaining a commitment to quality is another reason why Suntech is an essential solar partner. To meet the surplus demand for solar products, Suntech accelerated capacity expansion in the first quarter adding another three 30MW production lines and taking Suntech's annual production outpu to 325MW.

In addition, Suntech is on track with a key step in its move towards multi-gigawatt manufacturing with the construction of its new facility in Wuxi, China. The 540,000 square foot, 1GW capacity plant is scheduled to begin installation of new PV cell production lines in June 2007. With the acceleration of these initiatives Suntech has raised target 2007 year-end production capacity a second time to 480MW.

This capacity expansion is integral to Suntech's ability to deliver large orders of reliable solar products to meet tight customer schedules. "We cater to the diverse needs of our customers by ensuring that our products meet deadlines as well as performance specifications," said Dr. Zhengrong Shi.

Other Business Highlights

- Suntech has increased its BIPV sales and marketing activities especially in North America demonstrated by its letter of intent with Open Energy Corp. in May. Suntech intends to provide cost effective and high quality production of their SolarSave® PV Tiles and explore broad initiatives to expand BIPV product sales within the North American market.

- Suntech's innovative 20% conversion efficiency PV cell, based on its new low cost "Pluto" technology platform, is ahead of schedule achieving over 18% conversion efficiency in pilot production successfully, validating the commercial feasibility of this technology in comparison to conventional PV cell technology.

- To address the growing market for thin film and BIPV products, Suntech recently began construction on a thin film R&D and manufacturing facility in Shanghai. The initial phase with 50MW of capacity is expected to begin operation by the middle of 2008. Suntech projects the conversion efficiency of 6% to 9%. The thin film modules will be nearly 6 square meters in size contributing to a balance of system installation cost for that Suntech believes will be measurably lower than other thin film PV solutions.
