Lighting Choosing a commercial solar installer in Melbourne is not like choosing a residential installer. The stakes are higher, the systems are larger, and the compliance requirements are stricter. A 100 kW system on a warehouse roof is a business asset with a 25-year lifespan. Getting the installer wrong means lost generation, failed rebates, and warranty disputes that stretch for years.
This guide explains exactly what to check, what to ask, and how to separate a legitimate commercial installer from one that will leave you with problems.
For a full breakdown of what your business can claim, see our guide to VEU commercial solar rebate eligibility.
Why Commercial Solar Is Different
Commercial solar systems are between 30 kW and 200 kW under the Victorian Energy Upgrades (VEU) program . They are not domestic systems scaled up. They involve:
- Three-phase power and larger switchboards
- Higher grid connection voltages and DNSP negotiated contracts
- Structural roof assessments and load calculations
- More complex compliance and safety requirements
- VEU accreditation specific to the commercial and industrial solar activity
A residential installer who fits 6.6 kW systems on suburban homes may not have the accreditation, insurance, or technical capability to deliver a 100 kW commercial project.
Accreditation: The First Filter
Any installer offering commercial solar in Melbourne must hold the correct accreditations. This is not optional.
VEU accreditation for the commercial solar activity
Only an accredited person approved for the commercial and industrial solar activity can create Victorian Energy Efficiency Certificates (VEECs) . Accreditation for other VEU activities, such as lighting or hot water, does not cover commercial solar. Your installer must be specifically accredited for Activity 47.
SAA Accreditation
The Essential Services Commission requires that installation of the solar PV system be undertaken by a person who holds current Solar Accreditation Australia (SAA) accreditation . All electrical work must be completed by a licensed electrician (A Grade).
CEC Approved Products
All panels and inverters must be listed on the Clean Energy Council approved products lists . For systems under 100 kW, panel manufacturers must also participate in the Solar Panel Validation Initiative .
How to verify accreditation
Search the ESC’s accredited provider register and confirm your installer is approved for the commercial and industrial solar activity specifically. Ask for their accreditation number in writing. If they cannot provide it, walk away.
VEU Eligibility Requirements Your Installer Must Meet
Your installer’s job is not just to install panels. They must ensure your system qualifies for the VEU discount. This means the system must meet all of these requirements :
- Installed at a non-residential premises
- System size between 30 kW and 200 kW (module capacity)
- Minimum inverter capacity of 30 kVA as installed
- Connected to the relevant DNSP under a negotiated connection contract
- Only one solar PV system per National Meter Identifier
- Supports a monitoring portal accessible by the end user
- Complies with product warranty minimums: 10 years on panels, 5 years on inverters
If your installer cannot explain how your system meets each of these, they are not qualified to deliver a VEU-eligible commercial installation.
What a Fair Quote Looks Like
A commercial solar quote should be detailed. Vague quotes are a red flag.
What must be included
- Exact panel brand, model, and quantity
- Exact inverter brand, model, and quantity
- Mounting system and roof attachment details
- Switchboard work and electrical scope
- DNSP connection application responsibility
- Monitoring portal included
- Warranty terms for panels, inverters, and workmanship
- VEEC discount shown as a separate line item
- Federal incentive (STCs or LGCs) shown separately
- Net price after all incentives
What to avoid
- Quotes that say “Tier 1 panels” without naming the brand
- Quotes that say “rebate included” without showing the value
- Quotes that leave switchboard work or DNSP approval as “to be confirmed”
- Quotes that are significantly cheaper than others with no explanation
- Installers who ask you to apply for the rebate yourself
Red Flags to Watch For
No VEU accreditation for commercial solar
General VEU accreditation is not enough. Your installer must be accredited for Activity 47 specifically.
Cold-calling or door-knocking
Under VEU rules, accredited providers are banned from using telemarketing and doorknocking for lead generation . If someone approaches you that way, walk away.
No site assessment
A legitimate commercial installer will inspect your roof, switchboard, and site conditions before quoting. Quotes based on satellite photos alone are unreliable.
No DNSP pre-approval discussion
Your installer should explain the DNSP approval process and confirm they will manage it. Without DNSP pre-approval, the installation cannot proceed under the VEU pathway.
Pressure tactics
Limited-time offers, “today only” pricing, or aggressive follow-up calls are signs of a sales-driven operation, not a quality installer.
No local presence
Ask how long they have operated in Victoria. Ask for recent commercial installations in Melbourne. Ask for references you can contact.
