Global Solar Capacities
At the end of 2016 photovoltaic plants with an output of 303 GW were installed worldwide. It is expected that the annual increase will reach 100 GW by 2020 and that the installed capacity will reach between 3,000 and 10,000 GW by 2030.
Global Solar Capacity
The most inhabited areas of the Earth's surface receive between 150 and 300 watts per square metre of solar energy (insolation).
