CTDC Begins Construction of the First a-Si Thin-Film Solar Energy Rooftop System in China's Fujian Province

HONG KONG, June 12 /Xinhua-PRNewswire-FirstCall/ -- China Technology Development Group Corporation (Nasdaq: CTDC; "CTDC" ; "the Company"), aprovider of clean and renewable energy products and solutions focusing on solar energy in China, today announced that construction has begun on the Company's pilot amorphous silicon (a-Si) thin-film solar energy rooftop system at their production plant in China Merchants' Zhangzhou Development Zone("CMZD") in the Fujian province of southern China.

The a-Si thin-film rooftop project was designed by Terra Solar Global Inc., CTDC's strategic partner in the U.S., and in collaboration with China Merchants Shenzhen Electric Power Company ("CMSEPC") and CMZD. The project began in May 2008, with engineering, delivery and installation expected to take under six weeks, demonstrating the technology's capacity for rapid roll-out on demand. Upon completion in June, the Company expects this phase of the system to reach a capacity of over 7,500 Kilowatt hours (KWh) per year, providing environmental friendly energy to CTDC's manufacturing facility. The reduction in the building's dependence on the electrical grid will lead to an annual reduction of more than 4.7 tons of CO2 emissions.

"We are excited to have begun the installation of our pilot a-Sithin-film solar energy rooftop system, marking another milestone in CTDC's development as a provider of clean energy in China", Alan Li, Chairman and CEO of the Company, commented. "The construction of the solar power rooftop system is in complete accord with the renewable energy policy in China and demonstrates our commitment to the entire thin-film solar value chain. Meanwhile, we continue to focus on the commercialization of our SnO2 solar base plates in the near term."
