SOLF Solarfun Power Holdings CO., Ltd. ADS, Each Representing Five Ordinary Shares (MM)

SHANGHAI, Feb. 3 /PRNewswire-FirstCall/ -- Solarfun Power Holdings Co., Ltd. ("Solarfun" or "the Company") (NASDAQ:SOLF), a vertically integrated manufacturer of silicon ingots and photovoltaic "PV" cells and modules in China, today announced the introduction of "ECLIPSE," a new line of PV cells and modules with reduced light induced degradation (LID). The largest percentage of degradation of PV modules occurs during the first day of sun exposure. "ECLIPSE" reduces the impurity concentration in cells, therefore reducing the relative LID to about 1% from 2% to 3%, or less than 2W compared to about 4W to 5W for a 180W module equipped with standard cells. This results in an increase in electricity generation of about 1% to 2% more power over a one-, five-, 10-, and 25- year period when compared with standard modules. Peter Xie, President of Solarfun, commented, "We have devoted considerable resources and management attention to develop and produce differentiated products. We are proud to introduce this innovation in our new 'ECLIPSE' line with reduced LID. The advance is made possible by our vertically integrated manufacturing model and ability to control the quality of raw materials throughout the production process. By adjusting chemical properties in both the ingot-making and cell-processing phases of manufacturing, we have achieved a low concentration of impurity while still maintaining high yields. We remain committed to our strategy of continually enhancing our technology to produce differentiated and more efficient products for our customers."
