Solar irradiation problem Please calculate the value of direct (GD), diffuse (Gd), and reflected (GR) solar irradiation incident on a south-facing surface tilted at 45 degree on a clear day September 21 in the location with 30 degree Latitude and 85 degree W Longitude at 3:00 P.M. local solar time: (20 marks) Given a clearness number CN= 1 and reflectance of ground pg=0.2. Please show your working procedures, i.e. how you obtain necessary angles (solar altitude; solar azimuth; angle of incidence, etc.) in order to calculate the various solar irradiations.
