2012 has been a very dynamic and challenging year for the photovoltaic sector: The rapid cost reduction of photovoltaic power systems has continued throughout the year, leading to the emergence of new markets and market models. The market has continued to grow but at a slower pace than in the years before. At the end of 2012, about 100 GW of photovoltaics were installed worldwide, with contributions up to 6% of the electricity supply of some countries. The photovoltaic industry, on the other hand, has had the most difficult time of its young history, leading to a marked consolidation of the sector.
