Trevor makes a good point about feed in tariffs.
I got the system when the tariffs were 60c feed in. I think the Vic Govt has dropped that rate to 20-30c. You also need to consider using electricity during off peak times, which means programming dishwashers and washing machines to run btw midnight and 7am or during weekends. Off peak rates are significantly cheaper than peak rates (weekdays btw 7am and midnight).
