The global solar photovoltaic electricity (PV) market counted an additional increase in installed capacity of about 6.4 GW in 2009, reaching a total capacity of over 20 GW world-wide. This has been the most important annual capacity increase ever and is particularly impressive in light of the difficult financial and economical circumstances during the past year. In 2010, global cumulative installed PV capacity is expected to grow by at least 40%, while the annual growth is expected to increase by more than 15%.
During 2009, Germany remained the largest market, with Italy ranking second and Japan and the U.S. markets to follow. Germany most probably will remain the largest market in 2010, while new markets in particular from Southern Europe, Asia and the U.S. will grow significantly.
