What a 10kW solar system costs in the Northern Territory

What is different about the Northern Territory
At 32c a unit the Northern Territory sits 3rd of 8 on retail price, but it has one of the highest feed-in tariffs in the country at 9.3c, so exported power is worth something real here in a way it is not in most of Australia. It gets more sun than anywhere else on this list at 6 peak hours a day, so the same panels simply make more here. and its time-of-use peak is the flattest here, so a battery earns its keep on self-consumption and backup rather than on shifting power between rates.
The price, and the spread
$7,800 to $12,800 after rebates. The gap between those two numbers is $5,000 for the same equipment doing the same job on the same roof.
| Household uses | Their bill a quarter | System | After rebates | Saves a year | Pays for itself |
|---|---|---|---|---|---|
| 10 kWh | $391 | 5–6.6kW solar | $5,270 to $7,300 | $930–$1,110 | 5–7 years |
| 15 kWh | $537 | 6.6kW solar | $6,050 to $8,050 | $1,190–$1,560 | 5–6 years |
| 22 kWh | $741 | 10–13kW solar | $7,800 to $12,800 | $1,930–$2,400 | 4–6 years |
| 30 kWh | $974 | 10–13kW solar | $7,800 to $12,800 | $2,170–$2,970 | 3–5 years |
Where a 10kW system sits against the other sizes, in the Northern Territory.
Is this the right size for you?
A 10kW array suits a household using about 30 kWh a day, which in the Northern Territory means a bill around $974 a quarter at 32c a unit. Using much less than that and you are paying for generation you will export at 9.3c, which is close to giving it away.
Using more, or planning an EV, and you should be looking at the row below. An EV alone adds about 4.8 to 9 kWh a day.
What moves the price
Legitimately: a switchboard upgrade, a meter change, a two-storey or tile roof, scaffolding, and travel outside a normal service area. Each should be a line item you can see. Not legitimately: a separate charge for system design, a monitoring subscription the inverter makes redundant, and an extended warranty duplicating the manufacturer's.
$2,000 difference.
That is the gap between two quotes for the same 6.6kW system in the Northern Territory, 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.
