The rebate is mainly calculated through the STC (Small-scale Technology Certificates) scheme, and the value of your rebate depends on the size of your solar system and its location. The number of STCs assigned to a system is influenced by factors like system size and sunlight exposure (which is divided by zone).
Here’s an approximate estimate of the STC rebates for various solar system sizes in NSW based on current market trends (assuming an STC value of $35):
1. 1.5kW System: $990 – $1050 (28-30 STCs)
2. 2kW System: $1320 – $1400 (38-40 STCs)
3. 3kW System: $190 – $2100 (58-60 STCs)
4. 4kW System: $2640 – $2800 (78-80 STCs)
5. 5kW System: $3300 – $3500 (98-100 STCs)
6. 6.6kW System: $4356 – $4620 (129-132 STCs)
7. 10kW System: $6600 – $7000 (198-200 STCs)
8. 10.56kW System: $6969 – $7392 (209-212 STCs)
9. 13.2kW System: $8712 – $9240 (261-264 STCs)
