Although Japanese companies, such as Sharp and Kyocera, were leaders in innovation within the solar power industry, their positions were rapidly overtaken by Germany and young companies experiencing rapid growth, such as Germany’s Q-Cells, China’s Suntech Power, and USA’s First Solar.

To understand these topics, this paper conducts a case study of German industrial policy and two newly formed companies: Q-Cells and First Solar.
