Solar-powered garden light. This garden light recharges a battery in daylight and switches on at night,sometimes wired up to a motion sensor. The photovoltaic cell is the black area on top of the light. Photovoltaic cells convert the energy in sunlight into electricity. They are an economical and efficient power source,and do not pollute or add to global warming | |
