NSW benefits from strong solar radiation across most of the state, with Zone 2 STC multipliers for northern and central regions.
NSW commercial solar installations can access the following incentive schemes.
Adjust system size to see your NSW incentive breakdown at current certificate prices.
The zone multiplier determines how many STCs are generated per kilowatt of installed capacity. A multiplier of 1.536 means a 100 kW system in NSW generates 614 STCs over the remaining deeming period (4 years to 2030), worth approximately $23,962 at current certificate prices.
Large-scale Generation Certificates provide annual recurring revenue for solar systems above 100 kW in New South Wales. Unlike the one-time STC discount, LGCs generate income every year based on actual electricity production.
One LGC is created per megawatt-hour (MWh) of generation. At current prices of $47/LGC, a 150 kW system in NSW generating approximately 378 MWh per year would earn roughly $17,786/year in LGC revenue.
