Big Sun Energy Technology Inc. (Taiwan, China)

Big Sun Energy Technology Inc. was established in 2006, and then issued public offering in 2007. Solar energy industry can be divided from the above down into silicon material extraction, manufacturing, solar cells, solar modules and solar systems. As to the cost structure, the battery module cost takes 50% in the solar system, while electricity regulator 25%. In the solar module, 70% of the cost is taken by solar cells. Meanwhile, in the solar cells, 60% of the cost comes from the chip. As to the features of solar energy industry, the more upstream, the number of firms is less. Currently, as the technologies of refining silicon materials are mainly controlled by six companies in the United States, Japan, and Germany, capital expenditure is huge. So oligopoly market gets existed. As for the middle and lower part of solar energy industry, especially in the assembly of solar modules and systems, expected future situation will be more fierce competition. Domestic vendors also in the middle part (solar cells) are Big Sun Energy, Motech, E-ton Solar, Guanghua, Wangneng, Yu Jing, and Sun Microsystems. Abroad companies are Sharp, Kyocera, BP Solar, Q-Cells and etc. At present, Germany and Japan remains the world’s largest markets.There are adverse factors. One is the instability of upstream silicon raw material supply. Another is the less favorable self-developed technology than that of foreign firms.
