Comparison Between the Traditional and Solar System Street Lighting System

For more than five decades Iraq's people suffer from an increasing shortage of electric power due to the increased demand for electricity, and the disruption of electric power plants. Iraq is one of the countries that have a huge wealth type of renewable energy like more than 4000 sunny hours per year, one of the main loads of the national grid is the street lighting. This research made a full comparison between the conventional street lighting source sodium lamps (400 watts), Led lighting (200 watts), and Solar Street Lights. By using the Dialux program in lighting street which can show all the three types can give very good lighting and cover all the area required but in different wattage but same vision, even Solar Street Lights gives better vision. Using of Solar Street Lights will cut off huge loads from the national grid and cover the daily shortage of energy. Finally, this study shows a comparison among all the types depending on installation, energy consumption and running costs, safety, and warranty, maintenance and monitoring, a life span, and the cost for the same quality of lighting vision. And shows the Solar Street Lights is the best. Therefore, it will reduce electrical energy consumption in addition to its high operational life, which makes it superior to other traditional lighting types that consume electrical energy from the grid.
