A Solar lantern is a simple application of solar photovoltaic technology, which has found good acceptance in rural regions where the power supply is irregular and scarce. Even in the urban areas people prefer a solar lantern as an alternative during power cuts because of its simple mechanism.

Principle of Operation:
Photovoltaic cells are solid-state semiconductor devices that convert Solar Energy into Electricity (direct current). These Solar cells are connected in series or in parallel to obtain desired output and are called Solar modules.

How a Solar Lantern Works?
A solar Lantern is made of three main components - the solar PV panel, the storage battery and the lamp. The operation is very simple. The solar energy is converted to electrical energy by the SPV panel and stored in a sealed maintenance-free battery for later use during the night hours. A single charge can operate the lamp for about 2-8hours depends on the model.

A Solar Photovoltaic Lantern is a lighting system consisting of a lamp, battery and electronics all placed in a suitable housing. Made of metal, plastic or fiber glass and a PV module The battery is charged by electricity generated through the PV module. The lantern is basically a portable lighting device suitable for either indoor or outdoor lighting. covering a full range of 360 degrees. A lighting device which provides only unidirectional lighting will not be classifies as a solar lantern in the present context
