Lab assignment- intensity and horizon angles

Order Description

The professor asked us to determine the intensity at which a surface would be heated by the sun being at different horizon angles. to help determine the intensities, the locations and horizon angles are listed below:

1-Montreal, Quebec, Canada – 45 degrees N:
a- September 21, 45 degrees
b- December 21, 21.5 degrees
c- March 21, 45 degrees
d- June 21, 68.5

2- Charlotte, NC, USA – 35 degrees:
a- September 21, 55 degrees
b- December 21, 31.5 degrees
c- March 21, 55 degrees
d- June 21, 78.5 degrees

3- Miami, FL, USA – 25 degree N:
a- September 21, 65 degrees N
b- December 21, 41.5 degree
c- March 21, 65 degrees
d- June 21, 88.5 degree

4- If the only consideration is heating intensity, which of the 3 locations would be best for location solar collector to heat water or generate electricity?
