Solar prices in Darwin by system size
Installed prices are before rebates. The federal STC rebate is worked out at Darwin's own STC zone (zone 2, postcode 0800) and comes off at the point of sale.
| System | Panels | Installed, before rebates | Federal STC rebate | After STC rebate |
|---|---|---|---|---|
| 6.6 kW | about 15 | $6,900-$9,200 | 50 STCs, about $1,983 | $4,917-$7,217 |
| 10 kW | about 23 | $10,500-$13,900 | 76 STCs, about $3,013 | $7,487-$10,887 |
| 13.2 kW | about 30 | $13,900-$18,300 | 101 STCs, about $4,005 | $9,895-$14,295 |
STCs valued at $39.65 each, the price used across this site, verified 10 October 2026. Zone from the Clean Energy Regulator's postcode zone table. Panel counts assume the 440 W panels the size pages use. How the installed bands are built is on solar panel installation cost.
What a fair Darwin quote looks like
We don't sell packages or specials, so there is no Darwin deal to advertise here. The low end of each band is budget panels and a budget inverter; the high end is premium brands and more complex roofs. A quote well under the low end usually leaves something out, such as a switchboard upgrade, tile work, network fees or a smaller inverter. Ask for every item in writing, with the STC rebate shown as its own line, using the solar quote checklist.
Is the solar rebate dropping in 2027?
Yes. The STC rebate is calculated from deeming years, which fall from 5 to 4 on 1 January 2027. A 6.6 kW system in Darwin earns 50 certificates (about $1,983) if it is installed in 2026, and 40 certificates (about $1,586) from 1 January 2027: about $397 less at today's certificate price. The federal battery discount also steps down on 1 January 2027; see the Cheaper Home Batteries page for the schedule.
What's different about solar in Darwin
Darwin's STC zone has the highest rating of any capital city, so a system here earns more certificates than the same system in Sydney or Melbourne. Jacana Energy pays a higher Super Feed-in Tariff for exports between 3pm and 9pm, which suits a battery. The NT's Home and Business Battery Scheme closed in June 2025.

Which solar installer is best in Darwin?

Are solar rebates dropping in 2027?
Yes. The STC rebate is based on deeming years, which fall from 5 to 4 on 1 January 2027. A 6.6 kW system in Darwin earns 50 certificates if installed in 2026 and 40 from 1 January 2027, about $397 less at today's certificate price. The federal battery discount also steps down on 1 January 2027.
How long does solar installation take in Darwin?
The install itself is usually one day on site. From signing the quote, expect around 4 to 6 weeks, most of it waiting for the network operator's connection approval and the installer's schedule. Ask for both dates on the quote.
What's the best feed-in tariff in Darwin?
Jacana Energy pays 9.33 c/kWh for exports at any time, plus an 18.66 c/kWh Super Feed-in Tariff for exports between 3pm and 9pm (confirmed for 2026-27). The NT's evening premium is the strongest formal time-of-export signal in the country, which makes battery-shifted exports unusually valuable.
Is 10 kW solar enough to run a house?
In total energy, usually: a 10 kW system produces about 40 kWh on an average day (national average; Darwin averages about 5.2 peak sun hours a day). Compare that with the daily usage on your power bill. The gap is timing: panels produce in the middle of the day, so without a battery you still buy power in the evening.
Do solar panels work well in Darwin's climate?
Yes. Darwin averages about 5.2 peak sun hours a day. Output scales with sun hours, so the same system produces less in a lower-sun city, but the STC rebate is set by your postcode's zone rating, not by what the system actually produces.
