The angle of deviation of the normal to the surface from the local meridian is called as _________(a) Surface azimuth angle(b) Solar azimuth angle(c) Solar altitude(d) Hour angleI have been asked this question in quiz.I want to ask this question from Solar Radiation Measurement in chapter Solar Energy of Energy Engineering

Answer»

The correct answer is (a) SURFACE azimuth angle

The best I can explain: Surface azimuth angle is the angle of deviation of the normal to the surface from the local MERIDIAN, the zero point being SOUTH, east positive and west negative. And surface azimuth is different where it is an angle on a horizontal plane between the normal to a vertical surface and the north-south direction LINE.
