A solar lantern also known as solar lamp or solar light, is a lighting system composed of an LED lamp, solar panels, battery, charge controller and there may also be an inverter. The lamp operates on electricity from batteries, charged through the use of solar photovoltaic panel. Solar-powered household lighting can replace other light sources like candles or kerosene lamps. Solar lamps use renewable energy with infinity supply which is cheaper than standard lamps.

Solar lamps for use in rural situations often have the capability of providing a supply of electricity for other devices, such as for charging cell phones.
