Consider a thin rectangular (2m by 5m) solar panel. It is lying flat on a horizontal roof at Fox Glacier, New Zealand (latitude 43 degree south of the equator) at noon on June 21. The solar panel has an albedo of 0.2. What is the flux of energy coming into the upper surface of the solar panel in Watts per square meter (W/m^2)?
(Hint: Solar Constant: 1366W/m^2)
