Hi, I live in the UK! But I like reading about the systems available and the costs for Australia. Certainly you guys get great low price deals and are well subsidised by your government…unlike here in the UK where quotes are typically around A$25K for a basic 8.64kWp system using REC 320w panels and a SolarEdge 6000H inverter and no government subsidy!
I installed an East facing Enphase micro inverter system with 10 Panasonic 335w panels and IQ7X inverters. By doing all the work myself it cost me A$8.5K so far.
Next spring will be a further 10 panels facing south so eventually total system cost will be A$17K for a 6700wp system!
…then there will be the battery storage system @ +/- 9.6kW … $$$$$$$
