| SAA Certified Installers | SAA certification verifies that every installer on site holds the required Australian electrical licences and has been independently audited for workmanship quality and safety compliance. |
| VEU Approved Provider | VEU accreditation allows GES to offer eligible households additional discounts on heat pumps and hot water systems alongside the solar installation. |

11kW Solar with 40kWh Battery – Projected Energy Production & Bill Savings
Beyond rebates, the real financial benefit comes from long-term energy production and the ability to avoid grid electricity prices.
This Cranbourne East system is estimated to generate:
- Annual production: 15,298 kWh
- Annual bill savings: Approximately $1,940.85
These savings don’t include potential bill reductions from battery usage during peak hours, blackout protection, or feed-in tariff credits. When combined, the total financial benefit becomes even more significant.
Why Smart Homeowners in Victoria Are Securing Their Solar & Battery Rebates Before They Drop
The federal Small-scale Technology Certificates (STCs) program has been gradually reducing every year. Because of this steady decline, smart homeowners across Victoria are taking action now—locking in their rebates, reducing their power bills, and securing long-term energy independence.
Recently, our team completed the installation of an 11kW GoodWe solar inverter paired with a 40kWh Growatt battery storage system in Cranbourne East, VIC 3977. This installation perfectly demonstrates how Victorians are leveraging today’s rebates before they shrink.
Why the Drop in STCs Matters
Federal STCs act as an upfront discount when installing solar and battery systems in Australia. The number and value of STCs gradually decrease each year until the scheme phases out in 2030. This means that the longer homeowners wait, the smaller their rebate becomes—and the more they end up paying out of pocket.
Why You Must Act Before 2026
The anticipated 2026 STC reduction will impact both solar and battery rebates.
Solar STCs (2025 vs. 2026)
- 2025: 78 STCs for an 11kW system
- 2026: 65 STCs
Battery STCs (2025 vs. 2026)
- 2025: 372 STCs
- 2026: 336 STCs
This drop is confirmed and will take effect starting January 2026. Homeowners who delay until next year will simply not receive the same level of financial support.
Secure Your Rebate Before It Drops
If you’ve been considering solar or battery storage, now is truly the best time to act. By installing before the 2026 STC reduction, you could save thousands of dollars that will not be recoverable once the rebates drop.
