A solar street light is an eco-friendly lighting solution powered by solar energy. It uses solar panels to convert sunlight into electricity, which is stored in rechargeable batteries. These lights automatically turn on at dusk and off at dawn, conserving energy. They operate independently of the power grid, making them ideal for remote or off-grid areas. Solar street lights reduce electricity costs and contribute to a cleaner environment. They require minimal maintenance and have a long operational life. Modern designs include LED lamps for better brightness and energy efficiency. Built-in sensors and timers enhance functionality and reliability. Overall, solar street lights are a sustainable and cost-effective lighting option for public and private outdoor spaces.
