5W Solar home light is one kind of solar home system, supplying electricity for family lighting.
A solar-home-system uses a photovoltaic module to transfer solar energy to electricity to provide power to lights and small appliances in house. The system also needs a rechargeable battery, so that power is available at night and on cloudy days.
Solar-home-system brings huge benefits to homes in developing countries which are not connected to the main electricity grid.
They replace smoky, unsafe kerosene lamps with brighter lights, allowing work, study and social activities in the evening. They also power radios and cellphone chargers, enabling families to be in contact with the wider world. The smallest systems are solar lights, which can be moved around the home or carried outdoors.
Solar-home-system and solar lights already provide power to millions of homes in Asia, Africa and Latin America. Similar systems are also used in off-grid schools and health centers.
