Solar saw another record year in 2013, with as much around 35 GW of capacity installed according to IHS. China and Japan leaded the world in 2013 with 8.6 and 6.3 GW respectively.
This is especially staggering once you know that in 2008 and 2009 yearly installations were below ten gigawatts. Solar photovoltaic is in the middle of a exponential growth, as the graph in Cleantechnica shows all too clearly.
While these figures are quite impressive, there is more as 2014 could see the solar PV demand reaching a massive 49 GW according to NPD Solarbuzz.
