China has been the dominant producer of solar PV components for several years, with domestic manufacturers rapidly expanding capacity and pursuing economies of scale, aided in no small part by government assistance at the provincial (driven by local job creation goals) and national (supporting a key industry sector) levels.
Germany, on the other hand, has seen its production base dwindling over the past few years, while remaining the largest single-country end-market in the world. But this changed at the end of 2012 when China passed it. According to research in the upcoming NPD Solarbuzz Marketbuzz report, this trend is now set to continue for many years.
