The 6.6kW solar system has quickly become one of the most popular choices for households across Brisbane. With electricity prices continuing to rise and government incentives making solar more affordable, many homeowners are turning to this system as a smart way to reduce energy bills and gain long-term savings.
Brisbane’s sunny climate provides the perfect environment for solar panels to perform efficiently, making solar a strong investment for both medium and large households. However, with the growing demand for solar energy, the market has also seen an increase in low-cost providers and deals that look attractive at first but can lead to major problems later.
That’s why it’s important to know what to watch out for. In this blog, we’ll explore why a 6.6kW solar system is such a popular option in Brisbane and highlight five red flags to avoid when choosing your system.
Why Choose a 6.6kW Solar System in Brisbane?
For many Brisbane households, a 6.6kW solar system strikes the right balance between affordability and capacity. Here are the main reasons it has become a leading choice:
- Perfect for medium to large households: A 6.6kW system can generate enough electricity to cover the needs of a family with higher energy usage.
- Significant energy savings: Depending on your usage patterns, this system can greatly reduce reliance on the grid and cut power bills.
- Return on investment: With solar rebates and Brisbane’s favourable climate, many households see strong returns within just a few years.
- Optimised for Brisbane’s climate: Brisbane enjoys one of the highest levels of solar exposure in Australia, giving panels plenty of sunlight to work with year-round.
When chosen carefully, a 6.6kW system can provide consistent, reliable energy for decades. But to ensure that, it’s important to avoid some common traps in the solar market.
Red Flag #1: Suspiciously Cheap Prices

One of the most common mistakes homeowners make is being lured in by the cheapest price. While saving money upfront sounds appealing, “too good to be true” deals usually come with compromises.
- Inferior products: Low-cost packages often include panels and inverters from little-known brands that lack performance and durability.
- Poor installation standards: Cheap quotes may rely on subcontractors who aren’t properly qualified, leading to rushed or unsafe installations.
- Hidden extras: Some deals exclude essentials like monitoring systems or switchboard upgrades, which later add to the final bill.
How to spot genuine value:
- Check the panel and inverter brands included in the package.
- Ask for a detailed written quote with all inclusions listed.
- Research the provider’s reviews, particularly from Brisbane customers.
Paying a little more upfront often means a system that lasts longer and performs reliably.
Red Flag #2: No CEC Accreditation
The Clean Energy Council (CEC) is the governing body that sets industry standards for solar in Australia. Accreditation ensures both installers and systems meet safety and quality requirements.
- Why it’s important: Only CEC-accredited installers can connect your system to the grid and make you eligible for government rebates.
- The risks: Without accreditation, you risk poor workmanship, invalid warranties, and non-compliance with Australian standards.
- How to verify: The CEC website provides a public list of approved installers and products. Always ask to see proof of accreditation before proceeding.
Choosing a CEC-accredited installer is a must—it’s not worth risking your safety or investment otherwise.
Red Flag #3: No Warranty or Poor Warranty Terms
Solar is a long-term investment, and strong warranties provide peace of mind that your system will perform as expected for decades. Unfortunately, some providers offer limited warranties or make misleading claims.
- What to expect:
- Panels should include at least a 10–12 year product warranty and a 25-year performance warranty.
- Inverters typically carry a 10-year warranty.
- Common pitfalls: Some providers offer vague “performance guarantees” that don’t cover issues likely to occur in Brisbane’s conditions.
- How to protect yourself: Ensure warranties cover both defects and long-term performance, and check that they are backed by an Australian office or distributor, not just an overseas company.
A reliable warranty not only secures your investment but also reflects the provider’s confidence in their products.
Red Flag #4: Pushy Sales Tactics
Unfortunately, the solar industry has its share of aggressive sales tactics. Some companies focus on signing contracts quickly rather than helping you make an informed decision.
- Signs of pressure: Salespeople who claim a deal will “expire today,” constant follow-up calls, or offers that don’t allow time for comparison.
- Why it’s risky: Rushed decisions often lead to poor-quality systems that don’t suit your household’s needs.
- How to avoid:
- Request written quotes and take time to compare options.
- Ask providers to explain how the system matches your energy usage.
- Walk away if you feel pressured—reputable companies will let you decide at your own pace.
Solar is a long-term commitment, so decisions should be made based on research and trust, not sales pressure.
Red Flag #5: Lack of After-Sales Support
Installing solar is only the first step. Without proper after-sales support, you may struggle with maintenance, monitoring, or warranty claims.
- Why it matters: Solar systems should last decades, but occasional servicing or troubleshooting may be required. Without support, you could face higher costs and downtime.
- What to look for:
- Monitoring tools to track system performance.
- Clear customer service channels with local support.
- A Brisbane-based presence for timely response.
Reputable providers see solar as a long-term relationship, offering support throughout the lifespan of your system.
How to Avoid These Red Flags When Buying a 6.6kW Solar System in Brisbane
Here’s a checklist to guide your decision-making process:
- Confirm the installer is CEC-accredited.
- Compare quotes based on quality, not just price.
- Check warranty terms for both panels and inverters.
- Read customer reviews and testimonials from Brisbane homeowners.
- Ask about after-sales support and system monitoring.
- Insist on a transparent, itemised quote with no hidden costs.
Asking the right questions upfront will help you secure a solar system that’s reliable, efficient, and long-lasting.
