* Based on current STC price of ~$40, Zone 3 (Perth). Values decrease each year until 2030.
STC spot price: ~$40 (as of June 2026). Prices fluctuate — check the CER STC clearing house for current rates.
How to claim: Applied at point of sale — your installer handles the STC paperwork and deducts the rebate from your invoice.
How to claim: Apply via Synergy after installation (typically 2-4 weeks processing). You must have an approved battery from the Supported Solutions List installed before applying.
A 6.6kW system in Perth exporting 15kWh/day on DEBS could earn approximately $285/year (based on 40% peak at 10c + 60% off-peak at 2c). With a battery to shift exports to peak hours, earnings could be significantly higher.
How to claim: Apply via the WA Department of Communities. You will need your concession card details and Synergy account number. Credits are applied directly to your electricity bill.
Best combination for most homeowners: Federal STCs (upfront discount) + WA Battery Scheme (battery rebate) + DEBS (export earnings) + any eligible concessions.
