Power From The Sun :: Chapter 2

SOURCE: Abridged from Eddy (1979). 2.1.1 The Solar Constant The radiation intensity on the surface of the sun is approximately 6.33 × 10 7 W/m 2.Since radiation spreads out as the distance squared, by the time it travels to the earth (1.496 × 10 11 m or 1 AU is the average earth-sun distance), the radiant energy falling on 1 m 2 of surface area is reduced to 1367 W as depicted in Figure 2.3.
