200 kW of solar radiation is shining on a 300 m^2 parking lot. What is the insulation on the parking lot?
Show your calculations here:
a) less than 0.5 Sun
b) between 0.5 Sun and 1 Sun
c) more than 1 Sun

That's "insolation" ... not "insulation".'Insolation' is simply the intensity of solar radiation over some area.If 200 kW of radiation is shining on 300 m² of area, then the insolation is           (200 kW) / (300 m²) = (666 and 2/3) watt/m² .Note that this is the intensity of the incident radiation.  It doesn't say anything about how much soaks in or how much bounces off.Wait !  I just looked back at the choices, and realized that I didn't answer the question at all.  I have no idea what  "1 sun"  means.  Forgive me.  I have stolen your points, and I am filled with remorse.Wait again !I found it, through literally several seconds of online research.           1 sun = 1 kW/m².So 2/3 of a kW per m²  =  2/3 of 1 sun That's between 0.5 sun and 1.0 sun.I feel better now, and plus, I learned something.
