Commercial solar rebate · Systems from 100 kW to 1 MW

The solar rebate now covers systems up to 1 MW

Until now, the upfront solar rebate (small-scale technology certificates, or STCs) stopped at 100 kW. From 1 October 2026, systems between 100 kW and 1 MW can earn them too. That puts warehouses, factories, clubs, schools and farms in line for the same rebate homes and small businesses already get.

01 · What changed

How the 1 MW change works

Mid-scale systems used to fall into the large-scale scheme, with ongoing certificates rather than an upfront discount. That's what has changed.

What changedSolar systems with a total onsite capacity between 100 kW and 1 MW can now create STCs, the certificates behind the upfront solar rebate.
From whenSystems installed from 1 October 2026. The Clean Energy Regulator expects to open applications in mid to late November 2026.
Who it suitsCommercial, industrial and agricultural sites with the roof space and daytime load for a system over 100 kW.
How it's paidSTCs are usually assigned to the installer's registered agent in return for a discount on the price.
Still to comeThe regulator has said it is considering extra design, installation and compliance requirements, and will publish them. We'll design to them.
Existing large systemsSystems already accredited under the large-scale scheme stay there and keep creating large-scale certificates.

02 · Why it matters

What this changes for a commercial roof

01

Size to the load, not the cap

With the rebate stopping at 100 kW, the limit often set the system size. Now the system can be designed around your roof and your daytime load.

02

Stack it with a battery

The NSW battery discount can be combined with the federal solar rebate, so solar and storage together can come off the price upfront.

03

Mid-scale is an electrical project

At this size the supply, switchboard, export limits and network connection decide the job. That's our core trade.

03 · Scope of works

One contractor, whole job

We design and install commercial solar from site assessment and feasibility through to commissioning, and check rebate eligibility as part of every quote.

Answers before you enquire

Anything else, send us an enquiry or call Tim on 0409 986 882.

Is there a government rebate for commercial solar?

Yes. Commercial solar systems can create small-scale technology certificates (STCs), which are usually taken as an upfront discount. From 1 October 2026 this covers systems up to 1 MW, up from 100 kW.

What size solar systems qualify for STCs now?

Systems with a total onsite capacity up to 1 MW. The change covers the mid-scale range between 100 kW and 1 MW, for systems installed from 1 October 2026.

When can we claim for a system over 100 kW?

The Clean Energy Regulator expects to open applications in mid to late November 2026, for systems installed from 1 October 2026.

Can we combine the solar rebate with the NSW battery discount?

Yes. The NSW Government has confirmed its business battery discount can be combined with the federal solar rebate for commercial rooftops.

What happens to large systems already accredited?

Systems already accredited under the large-scale scheme stay there and continue to create large-scale generation certificates.
