Solar panels
Solar quotes move with roof shape, switchboard condition and whether you want a battery. The only system price on this page is the range NSW Climate and Energy Action publishes for a typical 6.6 kW system. It is not a national price list, and it is not a price for a battery.
Ask each installer to price the same panel size, the same inverter and the same roof, in writing. A cheaper quote that leaves off switchboard work is not the same job.
Published figures
Typical 6.6 kW solar PV system
$5,000–$10,000 AUD
The NSW page states this price for a typical 6.6 kW system and says the price already includes the large upfront discount through the Australian Government incentive. It also says the cost depends on system type and size, how easy the roof is to install on, and whether other electrical work is needed. Maintenance can be extra.

What the publisher says about running costs
Bill saving stated for a 4-person household with a 6.6 kW system
$1,400 AUD
A savings claim on the same NSW page, not a price for the system. The page also says the system would pay for itself in 5 years.

Payback stated for that 6.6 kW example
5 years
The NSW page says the system would pay for itself in 5 years. This is the publisher's statement, not a calculation by Tradie Guide.

What changes the price
- System size. The cited range is for a typical 6.6 kW system. A smaller or larger array is a different job. Compare kilowatts, not just the dollar line.
- The government discount already inside the range. NSW says the published price already includes the large upfront discount through the Australian Government incentive. A quote that adds that discount again, or strips it out without saying so, is hard to compare.
- Roof and access. Tile versus metal, storeys, shade and how the installer gets onto the roof all change labour. NSW says ease of install is one of the things that moves the cost.
- Other electrical work. An old switchboard, extra cabling or a meter change may be outside the panel price. Ask for those lines separately.
- Batteries and maintenance. A battery is not part of the cited 6.6 kW range. NSW also notes that maintenance can cost extra, and that you should check your home insurance.
Questions to ask
- What array size, panel model and inverter are in this price?
- Does the price already include the Australian Government incentive, the way the NSW range does?
- What switchboard or cabling work is excluded?
- Who lodges the connection paperwork with the distributor?
- What warranty is on panels, inverter and workmanship, and who honours each one?
- Is a battery quoted separately, with its own size and warranty?
Common questions
Does this range apply in every state?
No. It is the figure NSW publishes for a typical 6.6 kW system. Use it as a cited benchmark, then get local quotes. Other states are not given a dollar figure on this page.
Is the yearly saving a promise?
No. It is the savings line NSW prints for a 4-person household with a 6.6 kW system, next to a 5-year payback statement. Your bill depends on how much power you use while the sun is out.
