New Commercial solar rebate
In 2026, federal incentives for commercial solar in Cairns received a major expansion. The Federal Government expanded the Small-scale Renewable Energy Scheme (SRES) limit from 100 kW up to 1 MW, lowering upfront commercial solar installation costs by approximately 20%.
The New Commercial Solar Rebate Explained
What Is the Expanded Commercial Solar Rebate?
The Small-scale Renewable Energy Scheme (SRES) is Australia’s primary federal incentive for solar installations. Historically, the scheme’s upfront discount was strictly capped at 100 kW systems. Larger rooftop installations were forced into the Large-scale Renewable Energy Target (LRET), requiring businesses to claim Large-scale Generation Certificates (LGCs) gradually over years.
Under the expanded rules, systems up to 1 MW (1,000 kW) earn Small-scale Technology Certificates (STCs) upfront.
Core Benefits for Cairns Commercial Properties:
Immediate Capital Expenditure Reduction: Receive an upfront point-of-sale deduction equal to approximately 20% of your total commercial solar project.
No Waiting for Annual Certificates: Avoid the administrative friction and delayed returns of claiming annual LGCs.
FNQ Solar Zone 2 Advantage: Cairns and Far North Queensland sit in Solar Zone 2, generating a higher ratio of STCs per kilowatt installed compared to southern states—yielding maximum cash-value savings.

How Replenishable Energy Delivers Your Commercial Savings
Navigating commercial tariffs, Ergon Energy grid capacity, and federal certificate registration requires local engineering expertise. Replenishable Energy provides turnkey commercial solar management across Cairns and FNQ.
Free Energy Audit & Feasibility Assessment
We evaluate your facility’s Ergon Energy interval meter data, roof capacity, and daytime operational profile to determine if a 100 kW, 250 kW, or 500 kW+ system yields the fastest ROI.
Transparent Project Pricing
Your custom proposal highlights the gross system cost, the exact federal SRES rebate discount, the net out-of-pocket figure, and your estimated payback timeline (typically 2.5 to 4 years).
Ergon Energy & Network Approval
Our engineering team manages all grid-connection applications, dynamic export controls, and network documentation with Ergon Energy.
Engineering & Tropical Compliance
Systems are engineered specifically for North Queensland’s tropical climate, featuring high-temperature resistance, humidity protection, and Cyclonic Region C mounting specs.
Batteries, Demand Reduction, and Corporate Tax Benefits
1. Eliminating Ergon Energy’s Peak kVA Demand Charges
In Far North Queensland, commercial electricity bills are rarely just about total kilowatt-hours consumed. Heavy air conditioning units, industrial chillers, and large electric motors draw massive surge current during hot, humid afternoons.
Ergon Energy assesses commercial tariffs based on peak kVA demand, charging high fees based on your site’s highest 30-minute power spike each month. By combining a large-scale commercial solar array with automated battery storage, Replenishable Energy configures smart peak-shaving systems that automatically discharge battery storage during heavy motor startups, capping your peak demand charges.
2. Tax Depreciation & Capital Asset Offsets
Transitioning your business from buying grid power to owning on-site power generation shifts electricity costs from a pure, unrecoverable Operating Expense (OpEx) to an appreciating, depreciable Capital Asset (CapEx):
Accelerated Asset Depreciation: Commercial solar infrastructure and energy storage systems qualify as depreciable capital equipment under Australian tax law, allowing your finance team to write down system value against company revenue.
Cash-Flow Neutrality: When structured via green commercial finance, monthly energy bill savings frequently exceed the monthly finance payment—delivering immediate positive cash flow from month one.

Any commercial, industrial, or agricultural entity with an eligible building or roof space in FNQ qualifies. This includes warehouses, retail centres, resorts, processing facilities, schools, and agricultural properties. The system must be designed and commissioned by an accredited commercial retailer like Replenishable Energy using Clean Energy Council approved equipment.
You do not need to apply to a government portal or trade certificates yourself. Replenishable Energy acts as your registered agent, calculating the total STC value and subtracting it directly as an upfront point-of-sale discount on your invoice.
Yes. Mid-to-large commercial solar projects (100 kW to 1 MW) require engineering design, structural roof assessments, and Ergon Energy grid connection approvals. Establishing your site audit and design early ensures your business is queued for immediate installation and bill reduction.
