In this project we study how the effect of changing tilt angulations of the solar panel and (1) the variations in the incident sunlight affects the amount of electrical output from the (2) on the efficiency of solar panels in Baghdad location. The correct installation position will allow solar panels to be exposed to direct, unobstructed sunshine from 7am to 4pm every day ,this study determined that the optimum tilt angle for a PV panel changes throughout the year, we installed solar panels in four angles (20ْ,35ْ,45ْ,55ْ) as a fixed solar panel in august 2009 and in January 2010 . The results showed that the gains in the amount of solar radiation throughout the year received by the PV panel mounted at 350 for fixed solar panel to Baghdad location for all days year.
