Solar lantern

A solar lamp or lantern is a portable light fixture composed of an LED lamp,
a photovoltaic solar panel, and a rechargeable battery. Outdoor lamps may have lamp,
solar panel and battery integrated in one unit. Indoor solar lamps with separately-
mounted solar panels are used for general illumination where centrally generated power is
not conveniently or economically available. Solar-powered household lighting may
displace light sources such as kerosene lamps, saving money for the user, and reducing
fire and pollution hazards.
