Global investment in solar energy technologies from 2004 to 2015 (in billion U.S. dollars)

This statistic represents global investment in solar energy technologies between 2004 and 2015. In 2013, global investment in this field came to a little under 120 billion U.S. dollars. Europe, China and the United States are the main investors in this area. In 2015, some 67.44 billion U.S. dollars were invested into small-scale solar systems and 94 billion U.S. dollars into utility-scale systems. However, it must be noted that different entities may utilize varying minimal thresholds for the definition of utility-scale, which has been found to range from 5 to 50 megawatts. As of February 2015, one of the largest solar photovoltaic power plants, the Gujarat, is located in India and has a capacity of 856.8 megawatts.
