ACT Solar Rebate in 2025
Reviewed by
Leigh McInerney
The ACT solar rebate gives you a ripper of a discount right off the bat on your solar setup costs. What you see price-wise for these systems is what you cough up, no more, no less because the installers get the rebate and knock it off your final bill.
The solar rebate in the ACT for a 6kW system (most popular) is $1,955. This rebate may change based on the current STC trading price.
The amount of solar rebate you receive depends on the size of the solar system you install. For example:
Installing a 6kW Solar system in Canberra would cost:
Gross cost: $9,342 ( the actual cost of the system)
Rebate amount: $1,955
Net cost: $7,387 (price after deducting the rebate offered)
The table below provides you with the rebate amounts offered for solar system sizes of up to 100kW.
Rebate by System Size

|---|---|---|
| 1.5kW | 12 | $479 |
| 2kW | 16 | $638 |
| 3kW | 24 | $958 |
| 4kW | 33 | $1,317 |
| 5kW | 41 | $1,636 |

| 20kW | 165 | $6,584 |
| 30kW | 248 | $9,895 |
| 40kW | 331 | $13,207 |
| 50kW | 414 | $16,519 |
| 100kW | 829 | $33,077 |
If you wish to calculate the exact rebate amount you could get for your system, you will have to know the tradable small-scale technology certificates you can get for your system using this formula.
kW solar system x Deeming period in years x zone rating.
Canberra is in zone 3 with an STC rating of 1.382.
So, the number of STCs for a 5kW solar system bought in 2025 would be:
5 x 7 x 1.382 = 48 STCs.
To know the rebate amount you will get for your 5kW solar PV system, you need to multiply the tradable small-scale technology certificates by the current STC value in the market.
48 STCs x $39.90 (current STC value) = $1,915 (actual rebate you can claim for your 5kW system).
Note:
*The STC value is not fixed, and it varies depending on the solar retailer or installer you choose.
*The deeming period refers to the time interval (in years) between the time you install your solar system to the year 2030 ( when the government rebate scheme will end).
