If you live in Australia, you might have heard the rumours that commercial solar rebates are being phased out.

Just got thinking if your business has missed its chance to cash in on government support?

Hold on! Let’s set the record straight: the government rebates and incentives are still active, and in 2026, they’re more strategic than ever.

Australia remains a global leader in rooftop solar, but the rules of the game have evolved. It’s no longer just about covering your roof with solar panels and exporting cheap power to the grid.

In 2026, the smart move is pairing commercial solar with battery storage, demand management, and tax planning to maximise savings and control when and how your business uses energy.

From small cafes and warehouses to large manufacturing facilities and corporate headquarters, businesses of all sizes can still unlock substantial rebates, tax incentives, and funding opportunities.

The main goal is to understand how the current program works and how to stack them correctly before the rebates end.

Therefore, this guide breaks down how to maximise government rebates for commercial solar in 2026 in Australia, so you can slash power bills, boost energy independence, and make every incentive dollar count.

Let’s dive in!

In this blog post:

Understand the Federal Government’s Core Incentive Options

At the national level, Australia’s federal government continues to support commercial solar through several key programs. The rebate program includes:

Small-scale Renewable Energy Scheme (SRES)

This is one of the most popular commercial solar rebates across Australia. Under the SRES, eligible solar systems that are up to 100 kW generate Small-scale Technology Certificates.

These certificates are tradable and provide upfront discounts when you install solar. Your installer usually handles the paperwork, and the value is passed as a discount during installation.

Why does this matter for business owners?

STCs can directly reduce your upfront costs by tens of thousands, making solar a much more affordable long-term investment. This might sound exciting to many. But act sooner rather than later.

Why?

Because the value of STCs gradually decreases as we approach the RET (Renewable Energy Target) end date in 2030.

So, planning a 2026 installation can secure more certificates at higher values.

Large-scale Generation Certificates (LGCs)

For bigger commercial solar systems above 100 kW, it’s a different story. These systems fall under the Large-scale Renewable Energy Target and generate LGCs based on the electricity they produce each year.

These certificates are sold in the market, generating ongoing revenue, not just an upfront discount.

Why are LGCs a great option?

  • Provide cash flow over many years.
  • Can often outweigh STC savings for larger systems.

If your roof can support a system over 100 kW, you can easily scale up to access LGCs and create an annual income stream rather than just an upfront rebate.

New Federal Battery Rebate

From mid-2025, the federal government introduced battery rebates under the SRES framework, which continue into 2026.

In this battery home program, systems paired with solar can receive rebates for each usable kWh of storage installed up to 50 kWh.

This helps to:

  • Reduces battery cost by approximately 30%.
  • Enhances the value of your solar by allowing you to use more of the energy you generate rather than exporting it at a discount.

Pair solar with batteries wherever profitable. Solar alone saves you money, but paired with batteries, your business becomes more resilient and less exposed to low grid pricing.

How Can You Stack State & Territory Rebates and Grants?

Federal incentives are powerful, but stacking them with state-level rebates and grants can multiply savings.

Here’s what’s active or expected to continue in 2026:

New South Wales (NSW)

NSW supports commercial solar and batteries with:

  • STC rebates on solar.
  • Reset Peak Demand Reduction Scheme (PDRS) rebates for batteries. $1,600–$2,400 in addition to bonuses for VPP participation.

Here’s a pro tip! If you add a VPP-ready battery to existing or new solar installations, you can claim both state and federal rebates.

Victoria

Victoria continues its Solar for Business initiatives with:

  • Rebates for smaller commercial systems.
  • Interest-free loans and technical support.
  • Extra funding to encourage SME solar adoption.

You can pair your Victorian rebate with federal STCs and depreciation allowances for the best stack.

Queensland

Queensland has regional programs such as:

  • Energy audits for businesses.
  • Co-contribution grants.
  • Targeted agricultural support to reduce daytime energy costs.

Regional businesses often qualify for multiple small grants, so schedule an audit early in your planning to identify all available incentives.

Turn Australian Tax Deductions into Business Advantage: Here’s How!

Government support isn’t just limited to rebates; tax incentives can be just as valuable.

Instant Asset Write-Off & Temporary Full Expensing

Businesses installing solar can often write off the full cost of the system in the year it is installed, resulting in significant reductions in taxable income. This also:

  • Improves cash flow in the year of investment.
  • Can stack with rebates.

Before installing, consult your solar installer to ensure you’re claiming the maximum allowable deduction and that the structure aligns with your business’s tax year.

Standard Depreciation

Even if you don’t qualify for instant write-offs, solar is still a depreciating asset. You can claim deductions over its useful life, typically 20+ years, blending your return through ongoing tax savings.

Let’s Explore Strategic Funding & Innovative Financing Methods

You don’t have to own the system outright to enjoy the benefit:

Environmental Upgrade Agreements (EUAs)

There are councils, such as Environmental Upgrade Agreements (EUAs), that link loans to your property, allowing you to finance energy upgrades through your rates rather than traditional debt, often at better rates and longer terms.

In this method, solar starts saving money immediately, and a new cash-flow strategy makes solar accessible even without large upfront capital.

Power Purchase Agreements (PPAs)

With a PPA, a third party installs and owns the solar system, and you buy the energy at a reduced rate for 7–15 years.

What are the benefits:

  • Zero upfront cost.
  • Consistent electricity pricing.
  • Reduced risk.

A PPA may not generate STCs for you, but it can reduce out-of-pocket costs and be more financially advantageous for smaller businesses or those with constrained budgets.

Plan Your Install with Timing & Market Awareness

If you plan to install solar on your commercial property, timing is very crucial. The reason is simple and straightforward.

  • The rebate values decline over time. The SRES scheme reduces the number of certificates annually as 2030 approaches.
  • The battery rebates also step down periodically.

Therefore, all you need to do is book an appointment early, obtain free quotes, sign contracts, and schedule installations early in the financial year to secure the highest possible rebate.

How To Qualify for Maximum Returns?

In Australia, if you want to qualify for federal incentives, you must follow these two rules:

  • Panels and inverters must be Clean Energy Council (CEC) approved.
  • Installer must be accredited (Solar Accreditation Australia or equivalent).

Be aware! Skipping an accredited installer or choosing low-quality equipment can disqualify you from getting rebates, so always verify credentials and approvals.

Financial Metrics That Matter: Cash Flow, ROI & Payback

Understanding your commercial solar project isn’t just about grabbing rebates; it’s about making them count. Here’s how to approach it:

Build a 10-Year Financial Model

Include:

Upfront costs before rebates
Rebate cash inflows (STCs, state grants, battery subsidies)
Tax deductions
Avoided electricity purchases
Revenue streams (LGCs for large systems)

Then calculate:

  • Payback period
  • Net Present Value (NPV)
  • Internal Rate of Return (IRR)

In most cases, businesses with high daytime usage see paybacks in 3–6 years, which is far better than traditional capital investments.

End Notes

Beyond rebates and tax savings, commercial solar boosts your business in ways that don’t show up on a spreadsheet instantly. It brings:

Brand credibility: Customers increasingly want sustainable partners.

Energy resilience: During peak grid pricing or outages, solar + battery keeps the lights on.

ESG leadership: If you report on environmental goals, solar is a visible, measurable contribution.

By 2026, Australia’s commercial solar incentives will still be robust, but navigating them takes strategy:

Do this first:

  • Understand federal incentives (STCs, LGCs, battery rebate)
  • Explore state rebates and stacking opportunities
  • Talk to your accountant about tax deductions
  • Get multiple quotes and install early in the year
  • Choose an accredited installer and products

And then:

Consider financing alternatives like EUAs or PPAs
Build a financial model before signing on the dotted line
Look beyond dollars to brand and operational resilience

Finally, the clean energy transition isn’t just an environmental choice; it’s a smart commercial move. With thoughtful planning and the right rebate stack, commercial solar in 2026 can be one of the most lucrative sustainability investments your business makes.
