Just be careful with that retailer buy back rate, it can change at any time (unless your one of the lucky few on the 60 cents or 20 cents regulated rates).. Energy Australia just decided to drop the buy back rate from 7.7 cents per KWHr to 5.2 cents. They sent out letters saying that this was due to the IPART report recently released which sets the recommended 'range' for buy back. The 'range' recommended was anywhere from 4.9 cents to 9.3 cents, so there was no reason for Energy Australia to change their rate, they just did it because they can improve their margins ahead of the carbon tax hand back - and blame IPART.
As a result of that I'm going off-grid, I have had enough of them buying my generated power for next to nothing and then billing the guy next door 30 cents KWHR in peak for my contribution (assuming he is their customer).
I just bought a new panel for my shed system, which is totally off grid now (1Kw of panels), with a 400 amp/hr battery storage bank and inverter. It feeds the house (via a separate cable) and at night I can run most everything off that system.
I am looking for a supplier now to integrate my rooftop return to grid system with the shed system and create a totally off grid system. I know it will cost money but it will be my system and I will be independent of the politics, money grabbing, and Grid Charges. Backup generator of course.
Anyone care to recommend a system integrator?
