We're in the greater suburbs of Brisbane, this is a suburb called New Beith. This customer is looking for a larger system, there's three-phase supply to the property, larger shed, bigger house, more people in the house. So we've gone oversize on this location, so 17 kilowatts of solar on a 15 kilowatt inverter. We're maximising return on investment here, these guys being credit each quarter, the solar is a long game. So this is a long-term investment for them to give them the benefits of the system for longer. So 330 watt panels, 52 panels which gets them just to touch over 17 kilowatts. So we've got a 15 kilowatt three-phase inverter limit. This site also does have a single-phase Tesla Powerwall 2 to give a bit more self consumption, and also give single phase blackout protection for the property.

This is a forever house, the end game here is the solar in its own right, without the battery would probably be a four or five-year payback. As soon as you include a battery, you lengthen that payback period. So we're lengthening the solar and battery together to a six or seven year payback. Excellent savings here though. This is a large home, ducted air, you know it could be looking to bill of $800 to $1,200 a quarter. With the system we've got the battery we've got here, we can get that down to zero.

It's a win-win for the network as well. You know, this is distributed solar within this estate. The demand that this estate creates on the network during the day is a lot less than it would be without solar. So it's a win for the network, it's also a win on the carbon footprint of the property. Now these are big houses out here with big loads, we're reducing their dependence on the grid, we're reducing their dependence on fossil fuel, and we're producing our own power within our own property to make us more self-sufficient.
