Suntech and Standard Solar Reach 5 Megawatt Solar Panel Supply Agreement
Agreement strengthens both companies’ ability to respond to President Obama’s call to ‘harness the sun’

SAN FRANCISCO and GAITHERSBURG, Md., Jan. 27 — Suntech Power Holdings Co., Ltd. (NYSE: STP), the world’s leading manufacturer of photovoltaic (PV) modules, and Standard Solar, Inc. are looking forward to powering cleaner energy solutions throughout the Mid-Atlantic U.S. under a new agreement by which Suntech will supply up to 5 megawatts of photovoltaic solar panels to the Maryland-based solar developer and installer during 2009.

“Partnering with Suntech, a top-tier manufacturer offering a broad assortment of high-quality solar panels, better equips Standard Solar to fulfill its rapidly growing customer requirements from New Jersey and Pennsylvania to North Carolina and Virginia,” said Scott Wiater, Vice President of Procurement at Standard Solar.

“Suntech looks forward to partnering with Standard Solar in supplying cleaner, cost-effective solutions to businesses, government agencies and homeowners. In addition to reducing the dependence on highly polluting fossil fuels, we believe that the solar industry can also help to generate new domestic, green jobs,” said Roger Efird, President, Suntech America, Inc.

In his address after taking the oath of office and becoming the nation’s 44th President, Barack Obama called for Americans to “harness the sun . . . to meet the demands of a new age.”

“This agreement,” said Standard Solar President and Chief Executive Officer Anthony Clifford, “strengthens our ability to respond to this challenge. We cannot agree more with our new President when he added from the West front of the U.S. Capitol: “All this we can do. And all this we will do.

“Standard Solar looks forward to deploying Suntech’s high-quality panels in solar solutions that deliver cost-effective power. Recently, Standard Solar helped Kelly & Sons Electrical Construction source its electricity supply through a power purchase agreement with Washington Gas Energy Services.

Suntech recently achieved 1 gigawatt of global solar panel production capacity. In doing so, it completed an 18,000 square meter, 1 megawatt solar facade — the world’s largest to date — at its new world headquarters in Wuxi, China.
