A lot of Victorians are already taking our warning seriously — and honestly, good on ’em. We’ve been saying for months that the current federal solar and battery STC incentives won’t stay the same heading into the end of 2025. That’s why we’ve been urging homeowners to get in early with Green Electric Solutions, lock in today’s higher rebates, and pocket the maximum savings while they still can.
And here’s a perfect example: an Attwood homeowner (Paul Karroum) has just had their 11kW solar system with 48kWh battery installed, right on time — and they’re now set up to save a heap on their energy bills. In this blog, we’ll walk you through the real difference that timing made… and what would’ve happened if they waited until next year, even as early as January 2026, when STCs are expected to take another hit.
Real Savings Breakdown: Rebates Earned from This 11kW Solar with 48kWh Battery Install
| Rebate Type | Amount |
|---|---|
| 94 Solar STCs @ $38.00 each | – $3,572.00 |
| 446 Battery STCs @ $37.00 each | – $16,502.00 |
| Solar Victoria PV Rebate | – $1,400.00 |
| Solar Victoria Interest-Free Loan | – $1,400.00 |
| Total Rebate Value | $22,874.00 |
When you add it all up, this Attwood homeowner secured a massive $22,874 in rebates and incentives—just by installing their system before the expected STC reductions. These rebates won’t stay this generous for long, which is why acting early pays off big time. By locking in their 11kW solar system and 48kWh battery now, they’ve maximised every dollar of government support available. If you’re considering solar in Victoria, this is exactly the kind of saving you could still grab—but only if you move before the incentives drop.
Rebates 2025 vs 2026: How Much You’ll Lose If You Wait
For this exact GoodWe 11kW solar system with a 48kWh battery, here’s the blunt truth: waiting until next year — even January 2026 — will cost you real money. On the battery alone, you’d miss out on $1,994 in rebates ($16,502 today vs just $14,508 next year).
And on the solar side, you’d lose another $912 ($3,572 now vs $2,660 next year).
All up, that’s $2,906 straight out of your pocket just for delaying. This is exactly why so many Victorians are locking in their systems now. If you want to keep that money in your bank account — not lose it to shrinking incentives — now’s the time to move.
Technical Overview of 11kW Solar Plus 48kWh Battery Installation
Here’s a quick look at the professional, high-standard technical work that went into this installation:
SAA-Certified Installers & Compliance Standards
Our installation was carried out by fully SAA-certified and Clean Energy Council–accredited installers, ensuring every part of the job met strict Australian standards. From safety checks to grid compliance, everything was done by the book. You’re guaranteed a system that’s legally compliant, reliable, and built to last.
Optimised Solar Panel Placement for Maximum Output
The solar panels were positioned to capture the strongest sunlight throughout the day, taking roof angle, shade zones, and local weather patterns into account. This smart layout boosts daily energy production and ensures the homeowner gets the maximum return from their solar investment.
Professional Wiring, Protection Devices & System Safety
All wiring was completed using high-quality cabling, protected conduits, and safety devices to meet Australian electrical regulations. This not only keeps the system safe but also improves long-term performance. Clean workmanship means fewer issues, better airflow, and easier servicing in the future.
Battery Cabinet Setup, Ventilation & Monitoring Configuration
The 48kWh battery was installed in a well-ventilated, secure location to maintain temperature stability and extend battery life. We also configured the monitoring system so the homeowner can track energy use, charge levels, and savings in real time from their phone.
Inverter Positioning & Grid Connection Quality Checks
The GoodWe inverter was mounted in a shaded, protected spot to avoid heat stress and ensure consistent efficiency. After installation, we completed full grid-connection tests, safety isolation checks, and system calibration so everything runs smoothly from day one.
