The solar energy, collected by a polycrystalline silicon photovoltaic cell, powers two rechargeable nickel cadmium batteries. After sunset, they can yield the energy accumulated from the sun to spontaneously turn on the high efficiency leds. The duration of the light when fully charged is between 13 and 15 hours. The sun exposure time necessary to reload the energy expended after 13 hours of lighting is about 5 hours.
