• 1357 W/m²

• 1367 W/m²

• 1377 W/m²

Global radiation =      

• Direct radiation – Diffuse Radiation

• Direct radiation + Diffuse Radiation

• Direct radiation / Diffuse Radiation

• Diffuse Radiation / Direct radiation

The angle made by the plane surface with the horizontal is known as         

• Latitude

• Slope

• Surface azimuth angle

• Declination

Surface azimuth angle varies from

• 0 to 90°

• -90 to 90°

• 0 to 180°

• -180° to 180°

The hour angle is equivalent to

• 10° per hour

• 15° per hour

• 20° per hour

• 25° per hour

The complement of zenith angle is

• Solar altitude angle

• Surface azimuth angle

• Solar azimuth angle

• Slope

Solar radiation received at any point of earth is called

• Beam Radiation

• Diffuse Radiation

• Infrared rays

Solar radiation which reaches the surface without scattering or absorbed is called as

• Beam Radiation

• Infrared radiation

• Ultraviolet radiation

• Diffuse radiation
