How Do Solar Lights Work?
Solar lights function by absorbing sunlight during the day and then converting it into electrical current. Solar panels located underneath the light are made from photovoltaic cells, which work to convert the natural light via a solar battery. Although it might be confusing to learn that solar lights come with a battery, it is actually a special rechargeable battery that essentially works as the middleman. The battery charges throughout the day while the panels conserve the energy from the sun, and when nightfall arrives, a photoreceptor is able to detect the darkness, activating the light until the next morning. During the summer, solar lights should be able to shine bright all night, but during the winter, you may want to look out for any trees or obstacles that block the daylight, due to the lack of sunlight during this season. Having said that, most good quality solar lights are weatherproof, and can still pick up solar energy on overcast days.
