First Quarter 2009 Highlights

-- Total net revenues were $315.7 million in the first quarter of 2009

-- Gross margin improved to 17.8% for the first quarter of 2009, compared

with 0.6% for the fourth quarter of 2008.

-- Operating expenses were reduced by 24% to $35.1 million in the first

quarter of 2009 from $46.2 million in the fourth quarter of 2008.

-- Net income attributable to holders of ordinary shares was $1.8 million

or $0.01 per diluted American Depository Share (ADS). Each ADS

represents one ordinary share.

-- Suntech submitted 179MW of rooftop solar project applications for

China's national rooftop solar subsidy.

-- 100MW of Pluto production capacity commissioned with expected

conversion efficiencies of approximately 19% on mono-crystalline PV

cells and 17% on multi-crystalline PV cells.

-- Suntech maintained PV cell production capacity of 1GW at the end of the

first quarter of 2009.

"Considering the impact of seasonality, global economic headwinds, a contraction in PV project financing and falling sales prices, which greatly affected companies throughout the solar industry, we are pleased to have achieved revenues only 24% below the fourth quarter of 2008. This indicates the flexibility of Suntech's business model and customer preference for Suntech products," said Dr. Zhengrong Shi, Suntech's Chairman and CEO. "We are also pleased to have delivered a substantial sequential improvement in our gross margin, which demonstrates the success of our initiatives to reduce raw material costs and improve our non- silicon cost structure."

Dr. Shi added, "Europe continued to be the greatest source of solar demand in the first quarter. Going forward we expect further market diversification due to recently introduced stimulus initiatives in high potential markets. China's recently announced national solar subsidy; Japan's reintroduction of solar subsidies in 2009; and state incentive programs and the federal stimulus package in the U.S. should provide a strong foundation for mid-term growth. Suntech is uniquely positioned to address growth opportunities in all three of these markets through our 100-strong systems integration team in China, our Japanese subsidiary, and our multi- pronged downstream strategy in the U.S. We are already seeing the benefits of these initiatives with a 30MW utility scale solar project for Austin Energy in the U.S and our 30MW agreement to supply House Care with solar products in Japan."

"We are also making excellent progress with our global project development initiatives that will drive long term demand for Suntech solar projects. The Global Solar Fund has invested in companies that currently have 240MW of projects fully permitted and is targeting to finalize permits for at least another 360MW by the end of 2009. In addition, Gemini Solar is pursuing a pipeline of approximately 1.1GW of projects in the U.S. that we have either bid on, or are preparing bids for, and which are scheduled to be developed over the next 3 or 4 years."

"In this challenging economic environment, customers have an even greater focus on quality and track record - two areas where Suntech excels. We have now shipped more than 1,200MW of product since our inception and adhere to industry leading quality standards. With our mature sales channels, premium brand, high quality modules, and record of successful projects, we believe Suntech is a supplier of choice and best positioned to grow market share in this challenging market," concluded Dr. Shi.

RECENT BUSINESS HIGHLIGHTS

Project Development Initiatives

-- Suntech made significant progress with its strategic project

development initiatives. Suntech's equity method investment, the Global

Solar Fund (GSF), a European based investment fund, which qualifies for

investment company fair value accounting under AICPA investment company

guide, was created to make investments in private companies that own or

develop projects in the solar energy sector. GSF has invested in

companies that currently have 240MW of projects fully permitted and is

targeting to finalize permits for another 360MW by the end of 2009.

-- Gemini Solar, a Suntech joint venture with Renewable Ventures, a

Fotowatio company, is pursuing a pipeline of approximately 1.1GW of

projects in the U.S. that we have either bid on, or are preparing bids

for, and which are scheduled to be developed over the next 3 or 4 years.

China Market

-- Suntech recently submitted 179MW of rooftop solar project applications

for China's national rooftop solar subsidy.

-- Suntech announced the ground breaking of a 1.5MW rooftop solar project

in HuaiAn City, Jiangsu Province, China. This is expected to be the

first one megawatt plus rooftop solar system in Jiangsu Province.

Suntech is currently implementing a 3MW project for the Shanghai World

Expo.

Global Market Penetration

-- Suntech has shipped a total of more than 1.2GW of solar products since

inception of the Company.

-- Suntech intends to double its sales and marketing team in Europe over

the next three to six months to enhance localized service and support

for existing and prospective customers. Europe continues to drive

global solar demand accounting for over 80% of Suntech revenues in the

first quarter of 2009.

-- Suntech entered into an agreement with House Care Co. Ltd. under which

House Care will be an authorized distributor of Suntech in Japan and

distribute 30MW of Suntech solar products in 2009. Suntech targets over

40MW of sales into Japan in 2009.

U.S. Market

Pluto PV cell with a conversion efficiency of 17.2%. Both were produced

using standard grade silicon solar wafers on Suntech's commercial scale

production line.

-- Suntech is collaborating with the Swinburne University of Technology in

Australia to develop nanoplasmonic solar cells that are twice as

efficient and run at half the cost of those currently available.
