Solar street lights are self-sustaining lighting systems powered by renewable energy. They harness energy from the sun during daylight hours through photovoltaic panels, converting it into electricity and storing it in rechargeable batteries. At night, these stored energy sources are automatically utilized to illuminate the street or pathway, providing a safe and eco-friendly lighting solution. Solar street lights require no external power grid connection, making them ideal for remote locations or areas where traditional power sources are unavailable or unreliable. They also contribute to reducing carbon emissions and promoting sustainable development.
