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.
India is a nation in transition. Considered an "emerging economy," increasing GDP is driving the demand for additional electrical energy, as well as transportation fuels.India is blessed with vast resources of renewable energy in solar, wind, biomass
and small hydro. In fact, the technical potential of these renewable exceeds the present installed generation capacity. Unique in the world, India has the only Ministry that is dedicated to the development of renewable energies: the Ministry of New and Renewable Energy. This bodes well for the acceleration of renewable development throughout the nation –both to meet the underserved needs of millions of rural residents and the growing demand of an energy hungry economy.
