Suntech Starts First 1MW+ Rooftop Solar Project in Jiangsu Province / China's New Solar Subsidy Sets Foundation for Market Growth

SAN FRANCISCO, Calif. and WUXI, China, May 19 /PRNewswire-Asia/ -- Suntech Power Holdings Co., Ltd. , the world's largest manufacturer of crystalline silicon photovoltaic (PV) modules, announced today that it will build a 1.5MW solar system in HuaiAn City, Jiangsu Province, China in collaboration with Jiangsu Guoxin Asset Management Group Ltd. (Jiangsu Guoxin Group). The solar system, which is expected to be completed by October 2009, will be the first one megawatt plus, grid connected solar system installed in Jiangsu Province.

Suntech Energy Engineering, Suntech's China-based systems integration team, will design and install the 1.5MW solar system on 19,000 square meters of the rooftop of buildings housing a subsidiary of Jiangsu Guoxin Group in HuaiAn City. The project is expected to be eligible to receive the recently announced subsidy for roof-mounted solar systems.

Mr. Zujian Xu, Vice President of Jiangsu Guoxin Group and Chairman of Jiangsu Renewable Energy Development Co., Ltd. commented at the ground-breaking ceremony, "As a key investor in Jiangsu energy projects, Jiangsu Guoxin Group has actively responded to the call from the central government and strategic direction of the provincial governments to increase deployment of renewable energy such as wind power and biomass power. To date we have developed four biomass projects and one wind power project. This time we're very pleased to collaborate with Suntech, a leading company in the solar industry, to develop the first megawatt-sized rooftop solar project in Jiangsu province. We believe that this collaboration will deliver an important contribution to the solar industry in Jiangsu province.'

Dr. Zhengrong Shi, Suntech's Chairman and CEO, said, 'We are very pleased to collaborate with Jiangsu Guoxin Group to bring to fruition the largest rooftop solar project in Jiangsu Province to date. Roof space on factories and warehouses is an underutilized resource and ideal for roof-top solar systems. We look forward to implementing many similar rooftop solar systems across China.'

'China's new national solar subsidy should spark the growth of a strong domestic solar market enabling the gradual shift to renewable energy and sustainable development. With well over 1GW of Suntech solar products delivered worldwide since inception, Suntech will bring global experience and high quality solar systems to the China market,' Dr. Shi added. 'We believe that our systems integration team, which has over 100 people in major cities across the country, has the strongest capability to deliver turnkey solar systems in China and we already have a large pipeline of projects pending approval to receive the subsidy.'

Suntech's system integration team is one of the most experienced and capable in China. They have completed a range of technically complex building integrated solar systems, including the 120kW Beijing Jingya Hotel curtain wall, an 800kW Light Thru system at the Wuxi Airport, and the 1MW building integrated PV (BIPV) facade at Suntech's new headquarters in Wuxi. Suntech's system integration team is in the process of implementing a 3MW BIPV solar system for the Shanghai World Expo.
