Commercial Solar in Melbourne: Incentives, Approvals and What to Expect
Putting solar on a Melbourne business involves more than choosing panels. Incentives depend on system size, the right electricity distributor has to approve the connection, and a few sites need extra planning approval. This guide covers what is specific to Melbourne, so you know what to expect before you ask for quotes.
Melbourne businesses can combine federal certificates with a Victorian Energy Upgrades discount on systems between 30 kW and 200 kW. Your local distributor must approve the connection before installation, and most commercial roofs need no planning permit, with heritage sites the main exception. An installer who handles the approvals and incentives for you saves most of the paperwork.
Incentives available to Melbourne businesses
Support comes from both the federal and Victorian governments, and the mix depends on how large your system is.
Systems up to 100 kW earn small-scale technology certificates, and larger systems have earned large-scale certificates. The Federal Government has announced plans to extend small-scale certificates to systems up to 1 MW.
A discount for solar on non-residential sites, for systems between 30 kW and 200 kW. It is delivered through accredited providers, and its value moves with the certificate market.
How the cost is treated for tax depends on your business structure and the rules at the time. Ask your accountant, since we do not give tax advice.
The 1 MW extension was announced for systems installed from 1 October 2026, subject to regulations. We confirm the current position before quoting.
What the Victorian discount requires
The Victorian Energy Upgrades commercial and industrial solar activity has set conditions, so not every system qualifies. They include:
- The system is at a non-residential site and connected to the network
- The system size is between 30 kW and 200 kW
- The inverter capacity is at least 30 kVA
- Only one system per National Meter Identifier
- Panels and inverters are on the Clean Energy Council's approved lists
- The system includes a monitoring portal that you can access
- An accredited provider installs the system
Which distributor approves your connection
Melbourne is served by five electricity distributors, and yours depends on the suburb. The distributor assesses your application and sets the conditions on export and protection.
Not sure which applies? Your electricity bill names your distributor, or we can confirm it from your address.
What network approval involves
- Pre-approval from the distributor is needed before installation
- Systems above about 30 kW of inverter capacity can need a technical assessment or a negotiated connection
- Larger or more complex systems take longer, and any network upgrade is an added cost
- Systems must meet Victoria's remote shutdown requirements, which rely on a reliable internet connection
- An independent electrical inspector checks the work, and the system stays off until it passes

Planning permits and heritage sites
Most commercial roofs in Melbourne need no planning permit for solar. The exceptions are properties with heritage protection.
- Heritage Overlay: panels that are visible from a street, other than a lane, or from a public park need a planning permit
- Victorian Heritage Register: changes need a permit or exemption from Heritage Victoria before work begins
- Neither: no planning permit is needed
We check your address against the overlays at the start, so a heritage requirement does not surface after you have signed.
What suits a Melbourne business
Solar works best for businesses that use most of their power during the day, such as warehouses, factories, workshops and offices. Those loads line up with generation, so more of the electricity is used on site instead of exported. Sizing to your daytime consumption usually gives a better return than filling every square metre of roof. Our commercial solar cost and ROI guide explains how payback is worked out.

Frequently asked questions
Incentives, council approval, the distributor and sizing.
Is there a rebate for commercial solar in Melbourne?
Yes. Melbourne businesses can receive federal certificates on eligible systems, and systems between 30 kW and 200 kW at non-residential sites can also qualify for a Victorian Energy Upgrades discount. The two can be claimed together. Eligibility depends on the system, the installer's accreditation and the site, so we confirm what applies before quoting.
Do I need council approval for commercial solar in Melbourne?
Usually not. Rooftop solar on most commercial buildings does not need a planning permit. The exception is a site under a Heritage Overlay where the panels would be visible from the street, or a place on the Victorian Heritage Register, which needs approval from Heritage Victoria. We check the overlays for your address before design starts.
Who approves a commercial solar connection in Melbourne?
Your local electricity distributor does. Melbourne is served by CitiPower, Powercor, Jemena, AusNet and United Energy, depending on the suburb. Pre-approval is needed before installation, and larger systems may need a technical assessment or a negotiated connection, which can add time.
What size commercial solar system suits a Melbourne business?
It depends on how much electricity you use during the day and how much usable roof you have. Sizing a system to your daytime load generally gives a better return than sizing it to the roof alone. Our 40kW Melbourne guide shows what a typical mid-size system involves.
Can I claim the Victorian discount and federal certificates together?
Yes. Victorian Energy Upgrades states that eligible commercial and industrial solar systems can claim small-scale technology certificates or large-scale generation certificates alongside Victorian energy efficiency certificates. The rules on which certificates apply depend on system size, so check the current position with us before you buy.
