Choosing the right solar panel installer is the single most important decision you will make when going solar. The quality of your installation matters more than the brand on your panels, because a poorly installed system can underperform, void warranties, or even create safety risks. This guide explains how to find an accredited solar installer in Australia, the questions to ask, the warranties to demand, and the warning signs that should make you walk away.
Why Accreditation Matters
In Australia, accreditation is not optional if you want the financial benefits of going solar. To claim the federal STC rebate under the Small-scale Renewable Energy Scheme, your system must be designed and installed by an accredited professional using approved components.
There are two pieces of the puzzle to understand:
- Installer accreditation. Individual installers are accredited through Solar Accreditation Australia (which now administers the accreditation previously run under the Clean Energy Council). This confirms the person doing the work is trained and assessed to industry standards.
- CEC-Approved Retailers. Separately, the Clean Energy Council runs an Approved Retailer program. These businesses sign up to a code of conduct covering sales practices, documentation, and after-sales support. Choosing a CEC-Approved Retailer gives you an extra layer of consumer protection.
If an installer cannot show valid accreditation, you risk missing out on the rebate entirely and being left with a system that nobody will warrant. Always verify credentials before signing anything. You can compare solar companies on SolarCobber to find accredited operators in your region.
Questions to Ask Any Solar Installer
Before you commit, ask every prospective solar panel installer these questions:
- Are you accredited through Solar Accreditation Australia, and are you a CEC-Approved Retailer?
- Will the accredited person actually be on site, or is the job subcontracted?
- What panel and inverter brands do you use, and why?
- What warranties apply to the panels, the inverter, and your workmanship?
- Can you provide references or recent local installations I can check?
- How do you handle warranty claims and faults after installation?
- What export limits apply with my network, and how will you size the system?
A reputable installer will answer these clearly and in writing. Vague or evasive answers are a red flag.
Understanding Warranties
Solar warranties come in three distinct types, and you want all three to be solid:
| Warranty type | What it covers | Typical range |
|---|---|---|
| Product (panels) | Defects in the panels themselves | Around 12 to 25 years |
| Performance | Guaranteed minimum output over time | Often around 25 years |
| Inverter | Defects in the inverter | Around 5 to 12 years |
| Workmanship | The installer’s labour and installation | Often around 5 to 10 years |
The workmanship warranty is easy to overlook but vital. It only has value if the installer is still trading when you need them, which is one more reason to favour established, local solar installers with a track record rather than a business that may disappear next year.
Checking Reviews and Reputation
Online reviews are useful, but read them critically. Look for:
- A consistent pattern across many reviews rather than a handful of glowing comments.
- Detail about the actual installation and after-sales service, not just the sales pitch.
- How the company responds to complaints, which often tells you more than the praise.
It also helps to check how long the business has operated and whether it has a genuine local presence. SolarCobber’s directory lets you browse residential solar installers and read about companies operating in your area, so you can shortlist a few before requesting quotes.
Spotting Dodgy Operators
The solar industry has its share of poor operators. Protect yourself by watching for these warning signs.
Door-knockers and high-pressure sales
Be very cautious of unsolicited door-knockers or cold callers pushing “today only” deals. Quality installers rarely need to chase customers this way. High-pressure tactics, fake discounts, and demands for an immediate deposit are classic warning signs.
Deals that look too cheap
If a quote is dramatically cheaper than everyone else, ask why. Rock-bottom prices often mean budget components, rushed installation, subcontracted labour, or a business that will not be around to honour warranties. The cheapest system is rarely the best value over 25 years.
Pressure to sign before reading
Never sign a contract you have not read, and never feel rushed. A trustworthy installer gives you time, a clear written quote, and full documentation including system design and component details.
Missing accreditation or paperwork
If an installer cannot or will not provide proof of accreditation, walk away. Without it, you cannot claim the STC rebate and have little recourse if something goes wrong.
Local vs National Installers
Both local and national installers can do excellent work, so the decision comes down to what you value.
- Local solar installers often offer more personal service, quicker call-outs, and detailed knowledge of regional rules, network export limits, and weather conditions. They live and work in your community, which can mean more accountability.
- National installers may offer competitive pricing, established processes, and broad support networks, but service can feel less personal and call-outs slower in some areas.
Whichever you choose, the same fundamentals apply: accreditation, strong warranties, quality components, and a solid reputation. To find specialists near you, browse solar companies by state or jump straight to a region such as installers in Victoria.
A Simple Checklist Before You Sign
Run through this quick checklist before committing to any solar panel installation:
- Installer accreditation confirmed through Solar Accreditation Australia.
- Business is a CEC-Approved Retailer where possible.
- Written quote with full system design and component brands.
- Clear product, performance, inverter, and workmanship warranties.
- Genuine reviews and verifiable local installations.
- No high-pressure sales or unrealistic discounts.
- STC rebate applied transparently as an upfront discount.
Frequently Asked Questions
What is the difference between an accredited installer and a CEC-Approved Retailer?
An accredited installer is the qualified individual who designs or installs your system, accredited through Solar Accreditation Australia. A CEC-Approved Retailer is the business that sells you the system and has signed the Clean Energy Council’s code of conduct. Ideally you want both: an accredited installer working for an Approved Retailer.
Do I need an accredited installer to get the solar rebate?
Yes. To claim STCs under the Small-scale Renewable Energy Scheme, your system must be installed by an accredited professional using approved components. Using an unaccredited installer means forfeiting the rebate and likely your warranties too.
How many quotes should I get for solar?
Three is a sensible number. Comparing several quotes from accredited installers helps you gauge fair pricing, spot deals that are suspiciously cheap, and compare the components and warranties on offer.
Are cheap solar installers worth it?
Be careful. A much cheaper quote often signals budget components, rushed work, or a business that may not honour warranties. Over a 25-year system life, quality installation and reliable after-sales support usually deliver far better value than the lowest sticker price.
Should I choose a local or national solar installer?
Both can do great work. Local installers tend to offer more personal service and regional knowledge, while national companies may offer scale and competitive pricing. Focus on accreditation, warranties, and reputation rather than size alone.
Ready to Find an Accredited Installer?
The right installer turns solar into a reliable, decades-long investment, while the wrong one can cause years of headaches. Do your homework, insist on accreditation, and never let anyone rush you. When you are ready, compare solar companies on SolarCobber to request quotes from CEC-accredited installers in your area.
