STC Solar Battery Rebate Calculator
Find out how much you could save on a solar battery with the Australian Government STC rebate using our Solar Battery STC Calculator. At ND Solar Group, we help homeowners and businesses across Sydney understand exactly how many Small-scale Technology Certificates (STCs) their battery system may be eligible for and how this reduces the upfront cost of installation.
The federal battery rebate works in a similar way to solar panel rebates. Eligible battery systems generate STCs based on system type, capacity, postcode zone, and the remaining deeming period. These certificates are then traded for an upfront discount, lowering the price you pay for your battery.
How the Solar Battery Rebate Works
Solar battery STCs are calculated based on:
Battery system type and usable capacity
Your postcode zone and performance rating
The year the system is installed
The remaining deeming period until 2030
The deeming period represents how many years the system is expected to generate renewable energy benefits. This period decreases each year until the scheme ends in 2030, which means the number of STCs available reduces over time.
Installing a battery sooner can result in a higher rebate and greater overall savings.
