SOLUTION
Sunrise Hour Angle
1. Sun declination angle
n for July 16
2. Sunrise Hour Angle(HSR)
radians
Solar Constant (SC)
3. Extraterrestrial Insolation (Io) with SC=1.37 kW/m^2
kW / m^2
4. Clearness Index (KT): KT = IH/Io
5. Horizontal Diffuse Radiation (IDH):
6. Diffuse Ration on the Collector (IDC):
kWh/m^2-day
7. Reflected Radiation on the collector (IRC)
kWh/m^2-day
8. Horizontal Beam Radiation (IBH):
kWh/m^2-day
9. Sunrise Hour Angle on the Collector (HSRC)
radians
10. Beam Tilt Factor (RB):
11. Beam Radiation on the Collector (IBC):
kWh / m^2-day
12. Total Insolation on the Collector (IC):
kWh/m^2-day
