A Homeowner’s Guide to Solar Quotes in SA & QLD

Switching to solar in South Australia or Queensland is one of the smartest ways to cut your power bills, but not all solar quotes are created equal.

Before you commit, take a few minutes to check these 5 important things. It could save you thousands and prevent future headaches.

1. Check Who’s Installing Your System

Not every installer meets the same standards.

SAA Accreditation Make sure your installer is accredited by Solar Accreditation Australia (SAA). This is required for installers to be accredited to design and install systems under Australian standards and rebate eligibility frameworks.

NETCC Membership Look for the New Energy Tech Consumer Code (NETCC). This means the company is part of an approved seller framework focused on consumer protection, sales conduct, and quoting transparency.

If a company doesn’t meet both, it’s worth asking why.

2. How to Choose a Reliable Solar Company

Choosing the right solar company is just as important as choosing the system itself. A reliable installer should demonstrate long-term stability, real technical capability, and strong customer support.

Look for a company that has:

• Proven business history with consistent operation over several years

• SAA accreditation and NETCC approval

• Real installation experience, including residential and larger commercial systems

• Physical office or warehouse presence, not just online sales

• Qualified installers and proper supervision on-site

• Documented installations and project examples

• Strong after-sales support, including warranty handling and service response

  
  

It is also important to avoid companies that:

• Only operate as online sales businesses

• Have limited installation history

• Cannot provide clear documentation of past work or system performance

  
  

Because solar is a long-term investment, the company you choose should still be around to support your system years after installation.

3. Understand Your State’s Grid Rules (SA & QLD)

Each state has its own energy network rules, and they matter more than most people realise.

South Australia

SA Power Networks may require Flexible Export settings. This controls how much power you can send back to the grid at peak times. Make sure your inverter is compatible.

Queensland

If you live in a townhouse or apartment, you may need Body Corporate approval. Renters and landlords should also check eligibility for available rebates. Don’t assume this has been handled, confirm it is in writing.

4. Don’t Get Fooled by “Tier 1” Marketing

“Tier 1” sounds impressive, but it mainly refers to the manufacturer’s financial rating, not product quality.

A proper quote should clearly list:

• Exact solar panel brand and model

• Exact inverter brand and model

• System size (not just “standard system”) based on your usage and design requirements

Also check for:

• A monitoring app or smart meter

• Real-time tracking so you can see your energy production

If it’s not listed, it’s not included.

5. Watch for Hidden Costs

Some quotes look cheap upfront but don’t include everything.

Ask if the price includes:

• Switchboard upgrades (common in older homes)

• Roof type adjustments (tiles, steep roofs, multi-storey access)

• STC rebate (Small-scale Technology Certificates) already deducted

• Installation and paperwork handling

• Design adjustments required due to site conditions during installation

  
  

A good quote should be clear, fixed, and fully itemised.

6. Check Your Warranties (Corrected)

A strong solar system should come with three separate warranties:

• Panels (Product + Performance Warranty) – up to 25 years

• Inverter Warranty – typically 10 years

• Battery Warranty – typically 10 years

• Installation / Workmanship Warranty – typically 10 years

• 
  

The workmanship warranty is especially important, it protects the quality of the installation itself.

Final Word

Solar is a long-term investment, especially in sunny SA and QLD. But the quality of your system depends heavily on system design, correct sizing, and the quality of installation.

System sizing should always be based on your household’s energy usage, roof conditions, and future needs, not generic package sizes.

If you ever feel rushed to sign “today only,” take a step back. A good solar company won’t pressure you; they’ll focus on proper system design and clear explanations.

Take your time, ask questions, and make sure everything is in writing.

Your roof is an asset. Make sure the system you put on it is worth it.
