Solar irradiance is the power per unit area (surface power density) received from the Sun in the form of electromagnetic radiation in the wavelength range of the measuring instrument. Solar irradiance is measured in watts per square metre (W/m ) in SI units. Solar irradiance is often integrated over a given time period in order to report the radiant … WebPHYS-068 the Solar Spectrum revised John H. Scofield Dept. Physics & Astronomy, Oberlin College September 8, 2009 Page 3 of 9 Example 2: Calculate the total radiation intensity from a perfect radiator at a temperature T = 5000 K. Solution: This is a simple application of the Stefan-Boltzmann law. Recall that intensity is just power per unit area.
