Commercial Solar Rebates & Incentives in Melbourne
Commercial solar incentives could reduce your project cost by around 30% through Victorian VEECs, or around 20% through federal STCs, depending on the eligible pathway.
For Melbourne and Victorian businesses, Victorian energy efficiency certificates (VEECs) can substantially improve the financial return from an eligible commercial solar installation. Federal small-scale technology certificates (STCs) provide another opportunity to reduce the investment required, with eligibility now extending to qualifying solar systems up to 1MW. Lumenaus helps you assess which commercial solar rebates suit your site—so you can invest with a clearer understanding of installation costs, ongoing electricity savings and project payback.
Indicative percentages are estimates, not fixed government commercial solar rebate rates. Actual benefits depend on eligibility, certificate prices and project costs. Combined benefits require assessment and should not be assumed.
VEEC Commercial Solar Rebates
Commercial Solar VEEC Rebates in Melbourne
Turn your commercial solar investment into electricity savings—and a potential VEEC Commercial Solar Rebate. Victorian energy efficiency certificates (VEECs) reward eligible projects that reduce greenhouse gas emissions. For Melbourne and Victorian businesses, this incentive can improve project returns and reduce the effective cost of installing commercial solar.
Each VEEC represents one tonne of carbon dioxide equivalent emissions avoided under the program’s rules. An accredited provider creates the certificates, which can be sold to energy retailers required to meet Victorian Energy Upgrades obligations. The financial benefit is passed to your business through an agreed installation discount or payment.
How Is Your Commercial Solar VEEC Rebate Paid?
Eligible systems from 30kW up to and including 200kW: upfront discount
Under the standard commercial and industrial solar activity, eligible installations can receive an upfront discount through an accredited provider. Certificate entitlements use the activity’s prescribed calculations, avoiding the extended monitoring process required for larger projects. Your proposal should clearly identify the discount and eligibility conditions.
Systems above 200kW: payment after measured performance is verified
Larger installations may qualify through a project-based measurement and verification pathway. Energy savings are assessed using site data, typically involving around 12 months of post-installation monitoring. Payment follows the required assessment, certificate registration and agreed commercial arrangements—it is not automatically due on the installation anniversary. Assessing the project before construction helps protect eligibility and establish the necessary evidence.
What Determines the VEEC Price and Your Rebate?
The VEEC price changes with certificate-market conditions. Your actual VEEC Commercial Solar Rebate depends on the number of eligible certificates, the agreed certificate price, and any assessment, administration or trading fees. A quoted market price is therefore not necessarily the net amount your business receives.
Ask Lumenaus for a commercial solar assessment showing your potential VEEC entitlement, estimated net benefit and expected payment timing.
STC Commercial Solar Rebates
Commercial Solar STC Rebates Now Extend to Systems Up to 1MW
New STC Rebate Scheme
Federal STC incentives have expanded beyond 100kW, opening a new opportunity for businesses installing commercial solar systems above 100kW and up to and including 1MW.
Eligible systems installed from 1 October 2026 can access the expanded Small-scale Renewable Energy Scheme, helping reduce the investment required for larger commercial and industrial solar projects. One STC is generally equivalent to:
1 MWh of renewable electricity generated by a small generation Solar Panel System (up to 1MW in Capacity)
How Do STCs Reduce Your Commercial Solar Cost?
Small-scale technology certificates (STCs) represent eligible renewable electricity generation. Qualifying mid-scale solar systems receive a fixed five-year deeming period, allowing certificates to be created for an assessed quantity of future generation rather than waiting five years to earn them.
Businesses commonly assign their right to create STCs to a registered agent in exchange for an agreed discount on the system price. Your commercial solar proposal should identify the estimated STC benefit, eligibility conditions and when that benefit will be applied.
Each STC represents one megawatt-hour (MWh) of eligible renewable electricity generation.
For qualifying solar systems above 100kW and up to 1MW, STC entitlement is calculated using system capacity, location and a fixed five-year deeming period.
This allows the financial benefit of that assessed generation to be brought forward, helping reduce your installation cost.
What Determines Your STC Rebate?
Your potential benefit depends on your eligible system capacity, location, applicable certificate calculation and agreed STC price. Equipment, installation and scheme requirements must also be satisfied. Existing installations, extensions and staged projects require individual assessment.

Applications for the expanded mid-scale scheme are expected to open in mid-to-late November 2026. Eligible installation dates begin on 1 October 2026; certificate processing and payment are subject to application availability, approval and agreed terms. Information checked 19 October 2026.
