5 Common Solar Scams in Australia — and How Melbourne Homeowners Can Avoid Them
Australians are no strangers to scams. From suspicious emails to fake phone calls, most are easy to spot. However, solar scams are often far more convincing. They’re usually disguised as genuine offers, wrapped in technical jargon, and backed by slick marketing — making them harder to detect.
With solar rebates, rising power prices, and strong demand across Victoria, opportunistic operators have entered the market. To help homeowners protect themselves, Climate Green has put together this guide outlining five of the most common solar scams — and how to avoid falling victim to them.
Solar Scam #1: The Product Swap
This scam occurs when you are sold a specific brand or model of solar panels or inverter, but cheaper or inferior products are installed instead.
While less common than it once was, product swapping still happens — particularly when homeowners don’t know what to check.
What to Look For
Before installation, make sure you clearly understand:
-
Manufacturer name – for example, well-known brands such as REC, LONGi, GoodWe, Sungrow, or similar
-
Model number – which defines the size, efficiency, and type of equipment
-
Contract inclusions – the exact products must be listed in writing
On installation day:
-
Ask to see the solar panel labels (usually on the back of each panel)
-
Check the inverter box and side label once mounted
-
Do not allow installation if the products do not match your contract
If the wrong equipment arrives, stop the installation immediately and request clarification before signing anything.
Solar Scam #2: Fake or Fly-By-Night Installers
This is one of the most damaging scams. Fake installers take deposits with no intention of completing the installation, or they disappear shortly after the job is done.
These operators often:
-
Request unusually large upfront payments
-
Have professional-looking websites and ads
-
Offer prices that seem too good to be true
How to Spot a Fake Installer
Check the ABN
Ask for the installer’s ABN and look it up online. Warning signs include:
-
Recently registered businesses
-
Frequent name changes
-
Refusal to provide an ABN
Check their online footprint
Search the business name and ABN together. Look for:
-
Long-term reviews
-
Consistent business history
-
Real customer feedback (not just recent or generic reviews)
Check accreditation
Reputable installers are accredited and trained to meet Australian standards. Accreditation alone isn’t everything — but a lack of it is a red flag.
If something feels off, trust your instincts and walk away.
Solar Scam #3: Shonky Solar Contracts
Solar contracts can be complex, especially when finance or power purchase agreements are involved. Some scams rely on homeowners not reading the fine print.
What to Check Carefully
-
Interest rates – Are they fixed or variable after a certain period?
-
Contract length – Are there exit fees or penalties?
-
Performance claims – What happens if the system underperforms?
-
Hidden fees – Are monitoring, maintenance, or admin costs included?
-
Maintenance responsibility – Who is liable if servicing is required?
Solar finance can be a useful tool, but only when the terms are clear and transparent. Never feel rushed into signing.
Solar Scam #4: False Promises and Inflated Claims
Over-promising is one of the most common tactics used to close a sale quickly. Some claims simply cannot be guaranteed.
Lies to Watch Out For
-
Unrealistic output claims
System performance depends on roof orientation, shading, panel quality, inverter size, and location. Inflated generation figures should always be questioned. -
Exaggerated warranties
Always verify warranties directly against the manufacturer’s official documentation. -
Guaranteed savings or zero bills
No installer can predict future electricity usage or energy prices. Promises of “zero-dollar bills” are misleading. -
Inflated feed-in tariffs
Installers do not control electricity retailer tariffs. Savings based on unrealistic rates are unreliable.
Ask for calculations, assumptions, and written explanations. If answers are vague, walk away.
Solar Scam #5: The “Going Small” Trap
This scam involves convincing homeowners to install a much smaller system than they actually need, purely to offer a cheaper headline price.
While it may sound like a bargain, it often leads to:
-
Poor coverage of household energy needs
-
Missed savings
-
Ineligibility for future rebates or upgrades
What to Look Out For
-
Your electricity usage
Review recent bills to understand your average daily consumption in kWh. -
Future needs
EV charging, air conditioning, heat pumps, and home offices all increase demand. -
Pressure tactics
Claims that “bigger systems are unnecessary” should be backed by data, not opinions.
A system that’s too small defeats the purpose of going solar in the first place.
What Should You Do If You’ve Been Scammed?
If you believe you’ve been affected:
-
Contact your bank or finance provider immediately
-
Secure your accounts and personal information
-
Report the issue to relevant consumer protection bodies
-
Keep all documentation, emails, and contracts
Acting quickly can reduce financial loss.
