Solar home systems (SHS) are stand-alone photovoltaic systems. In rural areas that are not connected to the grid SHS can be used to meet a household's energy demand fulfilling basic electric needs. SHS 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 TVs for about three to five hours a day.
SHS typically include one or more PV modules consisting of solar cells, a charge controller and at least one battery.
They can contribute to the improvement of the standard of living by
- reducing indoor air pollution as SHS replace kerosene lamps,
- providing lighting for home study,
- giving the possibility of working at night and
- facilitating the access to information and communication (radio, TV, mobile phone charging).
