Germany is one of the world's top photovoltaics installers, with a solar PV capacity as of 2011 of almost 25 gigawatts (GW). As of 31st on October 2012, there were 31.62 GW of photovoltaics connected to the electrical power network. The German solar PV industry installed about 7.5 GW in 2011, and solar PV provided 18 TWh (billion kilowatt-hours) of electricity in 2011, about 3% of total electricity.
