Stand-Alone Solar Powered Systems

In a stand-alone system, there is no connection to the regional electricity supply, and the system provides all the electrical needs of the property.  Stand-alone systems are used in rural properties and out-buildings and by remotely sited equipment used in communications and instrumentation, broadcasting, navigation aids and environmental monitors when it is impossible or uneconomic to connect to the utility company. 

A bank of batteries is charged by the solar array during the hours of daylight and the energy stored is utilised whenever required, even at night.  The system is often enhanced by a diesel motor-generator to supply peak demands or during periods of poor light conditions.
