Technology for making the solar lantern

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. Solar lantern provide higher quality light than the candles or kerosene lamps. The possible applications for the system are emergency light source, light source in remote unelectrified villages, light source for the field, Adult education centre and other mass communication programmes. Solar Lantern designed to make solar energy more accessible. The lantern can provide up to six hours of high quality light, or a combination of light and radio output to bring news and information to households. 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 4-5 hours CEL has already developed the LED based solar lantern technology that comprehensible the specifications as standardised by Ministry of New & Renewable Energy (MNRE), Government of India. The company in a position to transfer the technology for possible buyers.
