A solar-home-system uses a photovoltaic (solar-electric) module to provide power for lights and small appliances. The system also needs a rechargeable battery, so that power is still available at night and on cloudy days. Solar home systems (SHS) are stand-alone photovoltaic systems that provide isolated off-grid households with amenity electricity for lights and appliances at a low cost. SHS can be utilized to meet a household's energy demand in rural locations that are not linked to the grid, providing basic electric necessities.
