S Solar system is one of the alternative energy that can used as energy sources. Solar energy is very useful! energy because in emergency condition where electricity often expeience power shortage due to excessive use of electricity while its revenues slightly. Therefore the author had the idea to make a Mp3 Player that uses solar cell module / solar cell that does not depend on state electricity. Solar cells is an active elemenent that can capture and convert sunlight into elecritical energy. The components used are PV modules,batettries,BCR,and expences ( Mp4 player ).The study was conducted from 08.00 pm until 17.00 in a sunny weather conditions. On cloudy or rainy weather can not be done charging. The result of different meausurements can be caused by various factors including : measuring instruments in use, components used, the weather, or human error itself. Suggestions from this study is a solar cell Mp4 player this is an alternative, innovative, and effective emergency and not used in the community because of the price of solar cells are relative large. Solar Mp4 player charger is used effective in a state of no better source of power or sources of electricity.
