How many watts of solar energy does the Earth receive on average per square meter?

The average solar power received by the Earth is 1,367 watts per square meter.

Based on the results of continuous observation of observation platforms on six satellites over the past 20 years, from 1978 to 1998, the value of the solar constant is 1,366.1 W/m2, with a standard deviation of 425 ppm and a fluctuation range. of 0.37% (1363-1368 W/m2) (Lean and Rind, 1998). Twenty years of satellite data have also revealed that the solar constant also fluctuates on different time scales.

In 1957, the International Geophysical Year decided to adopt 1,380 W/m2.

The solar constant value announced by the World Meteorological Organization (WMO) in 1981 is 1,368 W/m2.

Most publications use 1367 W/m2.
