SOLAR BATTERY REBATE CHANGES FROM MAY 2026: WHAT YOU NEED TO KNOW
Solar Battery Rebate Changes from May 2026: What You Need to Know
There’s been growing confusion around solar battery incentives in Australia, with many people believing the rebate is ending at the end of April 2026.
That’s not correct.
The rebate isn’t ending - it’s evolving.
From 1 May 2026, amendments to the Renewable Energy (Electricity) Regulations 2001 will come into effect, changing how solar battery incentives are calculated under the Small-scale Renewable Energy Scheme (SRES).
Quick answer: Is the solar battery rebate ending in 2026?
No - the solar battery rebate is not ending.
From 1 May 2026, the way the rebate is calculated is changing. The number of STCs (Small-scale Technology Certificates) will gradually reduce over time and vary depending on battery size, but the incentive will still be available.
WHY THE CHANGES ARE HAPPENING
Battery costs have been steadily decreasing. To keep incentives sustainable and aligned with the market, the government is adjusting how the rebate is applied.
The goal is to maintain a consistent discount of around 30% across battery systems - whether small, medium, or large, while gradually reducing support over time.
WHAT’S CHANGING?
1. More frequent reductions
The STC (Small-scale Technology Certificate) factor will now:
- Be reviewed and reduced every 6 months
- Decline at a faster rate than before
This means the level of incentive will gradually decrease over time rather than staying static for long periods.
2. System size will impact your rebate
The rebate will now taper based on the usable capacity of your battery system:
- 0–14 kWh → 100% of the STC factor applies
- 14–28 kWh → 60% of the STC factor applies
- 28–50 kWh → 15% of the STC factor applies
In simple terms, larger batteries will receive a lower rebate per kWh compared to smaller systems.

WHAT THIS MEANS FOR HOMEOWNERS
These changes don’t remove the incentive - they reshape it.
- Solar batteries are still supported under the SRES
- The rebate remains a meaningful cost reduction
- But system design and timing now play a bigger role in maximising value
For many people, this shift reinforces the importance of choosing a battery size that matches actual energy usage, rather than simply installing the largest system possible.
SHOULD YOU ACT NOW?
With the first round of changes beginning 1 May 2026 - and further reductions scheduled every 6 months — the value of the rebate will gradually decline over time.

THE KEY TAKEAWAY IS SIMPLE:
The solar battery rebate isn’t ending, but it is becoming more structured and gradually reducing over time.
As the market matures, incentives are being adjusted to reflect falling costs while still supporting uptake.
If you’d like tailored advice on how these changes impact your home or business, it’s worth speaking to a professional before making a decision.
