While tempting cheap solar deals may appear to you, they often lead to high repair costs because of faulty solar pv systems and dodgy installation practices. Some companies cut corners by subcontracting work or offering minimal after-sales support. Cheap solar systems may also lack performance and have a short lifespan.
Additionally, uneducated sales tactics and government rebate loopholes can leave you with unexpected electricity bills and worse problems. Remember, solar is a long-term investment, so prioritise quality over price to avoid disappointment and financial loss. Always research and choose reputable installers for a reliable solar solution
Cheap Solar Systems: Why Going Cheap Will Cost You More in the Long Run
Investing in solar energy for your home or business is a smart move, but there’s one trap you need to avoid: cheap solar systems. While those bargain-bin deals might look appealing upfront, they can lead to disastrous costs down the line—from poor performance to outright system failure.
In this guide, we’ll show you why quality matters and how cheap solar systems could cost you far more than you bargained for. If you’re serious about long-term savings and reliability, keep reading.
The Hidden Costs of Cheap Solar Systems
Cheap solar systems flood the market with promises of massive savings, but at what price? Behind the low upfront costs are significant risks that many customers discover too late. Here’s what you’re really paying for:
1. Low-Quality Solar Panels
Not all solar panels are created equal. Cheap systems often use non-branded, low-quality panels that deteriorate rapidly under the harsh Australian climate. Here are some common issues with bargain panels:
- Yellowing and Corrosion: Panels lose efficiency as they degrade.
- Delamination: Layers of the panel separate, reducing output.
- Hotspots: These are dangerous and can lead to cell damage or even fires.
What’s the solution? Premium panels like AIKO are built to last and come with a long warranty, giving you long-term performance and peace of mind.
2. Unreliable Inverters
The inverter is the brain of your solar system, converting solar energy into usable electricity. Cheap inverters may save you a few dollars upfront, but they’re notorious for breaking down and are often impossible to repair.
High-quality inverters, such as Fronius, SolarEdge, or Enphase, are more efficient, durable, and come with dependable customer support. They cost more, but they’ll save you from headaches and costly replacements.
3. Weak or Misleading Warranties
Cheap solar systems might advertise warranties, but here’s the catch:
- Many installers disappear before you need support.
- Non-branded panels and inverters may have no representation in Australia.
- Hidden costs like labour and shipping aren’t covered.
With trusted brands like AIKO, Tesla, Sigenergy, warranties include parts, labour, and shipping. This ensures you won’t be left in the lurch if something goes wrong.
4. Poor Installation Practices
Some companies lure you in with branded components but cut corners on installation to keep costs low. Common issues with bad installations include:
- Exposed or poorly routed cabling.
- Incorrect inverter placement in full sun.
- Poor panel positioning, causing overshadowing and inefficiency.
- Roof damage, such as broken tiles or poor sealing, leading to leaks.
When installed poorly, even the best components can fail. That’s why choosing Clean Energy Council-approved installers with a proven track record is non-negotiable.
Why Investing in Quality Solar Systems Is Worth It
While cheap solar systems may save you money upfront, the long-term costs can be staggering. Repairs, replacements, and inefficiency quickly add up, erasing any savings you thought you were getting. Here’s why quality solar systems are worth every penny:
- Long Lifespan: Premium systems last 25+ years, delivering consistent performance.
- High Efficiency: Better components mean you’ll generate more electricity over time.
- Reliable Warranties: Trusted brands back their products with comprehensive coverage.
For example, a quality system like AIKO Solar, paired with a reliable inverter like SolarEdge, will pay for itself in savings and performance, while cheap systems cost you more over time.

Don’t Get Caught in the Cheap Solar Trap
Here’s what typically happens when you fall for those “too good to be true” deals:
- You pay $4,000 for a system that only lasts 5 years.
- Repairs and replacements cost $1,000+ per visit.
- Energy output drops, forcing you to rely on the grid (higher bills).
In contrast, a quality 6.6kW system might cost $8,000 upfront, but it will deliver reliable, efficient power for 25 years or more, saving you tens of thousands of dollars.
What to Look for in a Reliable Solar Installer
To ensure you’re getting a quality system, here are some tips:
- Choose installers with Solar Accreditations Australia (SAA).
- Look for positive customer reviews and testimonials.
- Verify that warranties cover parts, labour, and shipping.
- Avoid deals that seem too good to be true—they often are.
