The tilt angle for fixed solar panel is the most important affecting factors on the amount of incident solar radiation intensity on the fixed solar panel yearly. The characterized solar street light change in working hours, relative to g on the change in daylight and night hours. By using PV systems Program to determine the optimum tilt angle of fixed solar panel solar street light to all the year in Baghdad city, and it is found that the optimum tilt angle values are ranging from 45 degrees to 65 degrees of average solar radiation that incident during a year period
