A Stand Alone System is a solar system that operates completely independent from any mains power grid. The biggest advantage of such a system is the huge saving you will have on the cost of power grid connections or generator fuel costs. Furthermore you will never suffer problems like black-outs, brown-outs or power surges, which can occur in some areas.

Where a Grid Interactive System feeds power to the mains grid, a Stand Alone System feeds power into a bank of storage batteries, therefore making you fully self sufficient. With the use of an Inverter, the electricity from the storage batteries is converted to 240 Volts, enabling you to live exactly as you would from mains power.

Depending on the size of a solar system, the battery storage can maintain your household's power requirements for several days without sunshine. However, many people prefer to invest in a diesel generator or wind generator to act as a backup. This is called a Hybrid System, a system that incorporates more than one source of power generator (e.g. solar modules, diesel generator and wind generator or even hydro power).
