Grid connect solar power means that you can generate your own clean energy and feed it back to the electricity grid. The surplus that you feed back will be credited against what you have used and thus save you money.

A grid connect system includes the solar photovoltaic panels and an inverter that changes the voltage of the power produced to match your mains electricity voltage, thereby allowing it to synchronise with mains power. You can then run household appliances from it and run the power meter backwards if you are generating more than you use.

The price that your solar generated power is sold at depends on your power retailer and the agreement you sign with them. Currently in Victoria all energy retailers must offer you a feed in tariff of at least 60cents/kWh for energy exported from your home though some offer higher rates of 66 and 68cents/kWh. This is more than 3 times what you currently pay for power.
