Solar lights are outdoor lighting solutions that use energy from the sun to illuminate spaces. They typically consist of a solar panel, a battery, and LED bulbs. During the day, the solar panel absorbs sunlight and converts it into electricity, which is stored in the battery for use at night. These lights are popular for their eco-friendliness and ease of installation, as they do not require wiring or electricity from the grid. Solar lights come in various styles, including pathway lights, garden lights, and security lights, making them versatile for different outdoor settings.
