During the day, the solar panel converts sunlight into electricity and recharges the battery . At night, the light turns on automatically using the electricity stored during that day. The number of hours the light stays on depends on your geographical location, weather conditions and seasonal sunlight availability. Place the solar light fixture in an area where it can receive direct sunlight for at least 8 hours each day. Shadowed locations will not allow the battery to charge fully and will reduce the hours of nighttime lighting. The selected location should not be near nighttime light sources, such as porch lights, street lights or pool lights , as these may cause the solar light to turn off prematurely.
