Off-grid systems are stand-alone photovoltaic systems that offer a cost-effective mode of supplying amenity power for lighting and appliances to remote off-grid households. Off-grid can be used to meet a household’s energy demand fulfilling basic electric needs. The off-grid system provides power to hundreds of thousands of households in remote locations where electrification by the grid is not feasible. Off-Grid usually operate at a rated voltage of 12 v direct current(dc) and provide power for low power dc appliances such as lights, radios, and small TV’s for
about three to five hours a day.
