A Solar Home System is the simplest system, usually with a 12 V DC circuit, one or more solar panels, a control panel, one or more batteries, several lamps and power sockets. It is a stand-alone system for small houses and businesses without regular power. It is suitable for lights, charging phones, a water pump and other small 12 V DC appliances. A Solar Home System can either be a “plug-and-play” packet or can be designed according to the needs of power.
A Solar Residential System is a more advanced system that can be used for homes, offices, clinics, as well as for hotels and larger buildings, usually with several solar panels, a controller unit, batteries and an inverter (converter) that transforms the low DC voltage into 220 V (or 110V) AC, meaning that it can be used with ordinary applications and combined with regular power. It can therefore also serve as a supplement and a back-up system in locations with frequent power cut (load shed). The system should be designed according to the specific needs for power.
