Abstract
In perfect tracking condition, the angle between normal to solar collector’s surface and sunbeam, known as incident angle is zero to gain maximum energy collection and efficiency. The role of collector orientation on solar geometry has been studied to increase the collection of solar radiation. In current work, the focused surface orientations are (i) horizontal (ii) tilted (iii) zenith angle tracking (iv) azimuth angle tracking and (v) dual axis tracking. Sun earth relations (solar geometry) have been solved for a day, seasons and year. Azimuth angle tracking has been suggested over a zenith angle rotation for single axis tracking developers. The zenith angle rotation is favoring only in winter season. In perfect tracking, the tilt angle should be equal to zenith angle and surface azimuth should be equal to solar azimuth angle.
