Solar street lights are lighting systems that use solar panels to collect and store sunlight during the day, converting it into electrical energy to power LED lighting systems at night. This renewable energy source is environmentally sustainable and cost-effective as it eliminates the need for grid-connected electricity supply.They are also ideal for public parks, parking lots, and pedestrian walkways, providing improved safety for pedestrians and motorists.A road is a thoroughfare for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, whose primary function is to serve as public spaces, the main function of roads is transportation.A street light, light pole, lamp pole, lamppost, street lamp, light standard, or lamp standard is a raised source of light on the edge of a road or path. Similar lights may be found on a railway platform.
