8 UNIVERSITY OF FLORIDA Solar Utilization Solar Availability Nomenclature: Irradiance: the amt. of solar radiant energy falling on a surface per unit area and per unit time, kW/m 2 Example: mean extraterrestrial irradiance on a surface normal to the solar beam on the outer fringes of the earth’s atmosphere is approx. 1.35 kW/m 2 or 428.15 btu/hft 2 . Due to earth’s elliptical orbit, this varies +or- 3.4% during the year.
