  An important parameter that affects PV panel performance of a solar power
system is the incident solar radiation with the panel or panel's area of
exposure to the sun. The direction and tilt angle of a PV panel are two
important factors in PV system design. This paper itself presents the
calculation of the optimum installation angles for the seasonal adjusting of
solar cell panels considering apparent motion of the sun. Daily adjusting for
optimal tilt angle can increase the received energy from the sun. However,
making trade-off is required because changing the panel angle daily costs lots
of endeavour, so we designed seasonal angles for installation of panels.
