Solar street lights are outdoor lighting systems that use solar panels to collect and convert sunlight into electricity. This electricity is then used to power LED (Light Emitting Diode) lights during the night. Solar street lights are becoming increasingly popular as they are eco-friendly and cost-effective. They don't require any external power source or electricity grid connection, making them ideal for remote areas where access to electricity is limited. They are also easy to install and require minimal maintenance. Solar street lights usually consist of solar panels, rechargeable batteries, LED lights, a controller, and a pole. During the day, the solar panels collect sunlight and convert it into electricity, which is stored in the batteries. At night, the controller automatically turns on the LED lights using the stored energy from the batteries. Solar street lights are suitable for a range of applications, including residential streets, parking lots, highways, and rural areas. They provide a reliable source of lighting, which improves safety and security for pedestrians and motorists. They also reduce energy consumption and carbon emissions, making them a sustainable and environmentally friendly lighting option.
