What the spread is
The low and high columns are the same equipment doing the same job. What separates them is the installer's overheads, how full their diary is that month, and what they think you will agree to. It is the largest number on this page that has nothing to do with your house.
What moves the price legitimately
A switchboard upgrade, a meter change, a two-storey install, a tile roof rather than tin, scaffolding, and travel outside a normal service area. All of those are real and all of them should be quoted as line items rather than absorbed into a number. Ask for each in writing before you sign, because they are the variations that turn up afterwards.
What does not
A separate charge for system design and engineering, which is part of quoting the job. A monitoring subscription, when the inverter already monitors. An extended warranty that duplicates cover the manufacturer already provides. Those three are where padding usually lives.
$2,000 difference.
That is the gap between two quotes for the same 6.6kW system in New South Wales, in the same week. Not build quality, not a better job. Overheads, how full the diary is that month, and what the person at your kitchen table thinks you will agree to. On solar with a battery the same gap is $7,900.
Closing that gap is what I do. I already know what installers in your area are quoting this month for this equipment, so I get you the bottom of that range for the same system other companies charge thousands more for. It costs you nothing. The installer pays me, and only if you go ahead, which is why there is no reason for me to push you at a bigger system than you need or at a dearer installer.
