Answer 1

shape of greenhouse
orientation of structure
cladding material used and its condition

Question 2

At what angle does most of the light pass through the glass of a protective structure?

Answer 2

an angle less than 40 degrees

Question 3

Answer 3

the amount of light passing through glass is dependent on the angle of the glass and angle of the light rays

Question 4

At what angle is most light reflected (does not enter the greenhouse?
