We all are aware that the shadows are longest during early morning and late afternoon/early evening when the sun appears low in the sky. Considering this aspect among others, the direction of the panel has to be planned so that it gets maximum exposure for power generation. Another associated factor here would be the tilt angle, which is the angle of PV arrays with respect to the horizontal line (latitude). The tilt angle is a dominant factor affecting the radiation of a PV array. Therefore, optimization of tilt angle should also be taken into account during the different seasons of the year.
