How the battery rebate estimate works
The calculator uses battery size and a hidden STC value assumption to provide a practical estimate before you request a site-specific quote.
1. Choose your battery size
Use the slider from 5 kWh to 50 kWh. Larger batteries may receive a higher rebate, but the calculated benefit is weighted by capacity bands.
2. Check the estimate
The calculator shows an estimated upfront battery rebate using the current 2026 factor and a hidden STC value assumption of $37.
3. Confirm eligibility
A final quote needs to confirm battery model eligibility, solar compatibility, switchboard condition, site access and current program rules.
