SAA Accreditation Explained: What Solar Buyers Need to Verify Before Signing

Solar accreditation in Australia changed in 2024. The Clean Energy Council (CEC) used to run the accreditation scheme; the Solar Accreditation Australia (SAA) scheme replaced it. The change matters because federal STC rebates, typically $3,000–$7,000 off the cost of a residential solar install, require an accredited designer and installer. Without one, you don’t get the rebate.

What changed in 2024

The CEC accreditation program for solar installers, designers, and supervisors was discontinued in early 2024. A new scheme administered by Solar Accreditation Australia (SAA) replaced it. The change was driven by industry concerns about CEC governance, accountability, and complaint handling.

Practical implications:

• All solar installers and designers must now hold SAA accreditation (not CEC)
• Existing CEC accreditations were transitioned to SAA, but installers had to re-register
• The federal STC rebate scheme (run by the Clean Energy Regulator) now requires SAA accreditation
• Some installers who were CEC-accredited are not SAA-accredited. They didn’t transition.

This last point is important. Not every installer who was operating in 2023 still holds valid accreditation in 2026. Verification is your responsibility before signing.

Why accreditation matters for STCs

STCs (Small-scale Technology Certificates) are the federal rebate mechanism that makes residential solar affordable. A typical 6.6 kW system on the Gold Coast generates around 90–100 STCs at 2026 STC values, worth roughly $3,500–$4,000 off the system cost.

To claim STCs, the installation must be:

• Designed by an SAA-accredited designer
• Installed by an SAA-accredited installer
• Supervised by an SAA-accredited supervisor (often the same person)
• Using approved (CEC Approved Products List, still called by that name) panels and inverters
• Compliant with AS/NZS 5033, AS/NZS 4777, and the local DNSP’s connection rules

If any of these are missing, the STC claim fails. The buyer pays the full system price.

How to verify accreditation

Two checks before you sign anything.

1. Verify the installer’s SAA accreditation

The SAA maintains a public register at solaraccreditation.com.au. Search by the installer’s accreditation number (which they should provide. If they don’t, that’s a red flag.) or by their business name.

What to confirm:

• Accreditation is current, not expired
• The accreditation type matches the work: designer, installer, or supervisor as appropriate
• The category covers the install: Grid Connect Solar PV, or Stand-alone PV for off-grid, or Battery for storage
• No suspensions or warnings on the record

2. Verify the panel and inverter are on the CEC Approved Products List

The Clean Energy Council still maintains the Approved Products List (despite the accreditation scheme moving to SAA). The list is at cleanenergycouncil.org.au.

What to confirm:

• The exact panel model on your quote is on the list
• The exact inverter model on your quote is on the list
• Battery models, if applicable, are on the list

This catches a common scam: a quote specifying brand X panels at install but actually delivering brand Y. If the delivered product isn’t on the list, the STC claim fails.

What a legitimate quote looks like

A compliant solar quote includes:

• Designer’s SAA accreditation number
• Installer’s SAA accreditation number (often the same person, sometimes different)
• Exact panel make, model, and quantity
• Exact inverter make and model
• STC discount itemised: the value of the STCs being claimed and how it’s applied to the price
• DNSP connection process: usually included in the quote, with the application paperwork separate
• Schedule of works: site visit, install date, commissioning, handover
• Warranty statement: both manufacturer and workmanship
• Standards compliance statement: explicit reference to AS/NZS 4777 and AS/NZS 5033

Be wary of quotes that:

• Don’t list the accreditation number
• Use vague panel descriptions (“tier 1 panels,” “premium inverter”)
• Claim “we’ll handle the rebate paperwork” without itemising the STC value
• Have no clear schedule or warranty terms

The STC math, simplified

STC value fluctuates with the market. They’re tradeable certificates. As of 2026, STC values are around $35–$40 each (down from peaks of $40+ in 2023, slowly declining as the scheme winds down toward its 2030 end date).

For a 6.6 kW system on the Gold Coast in 2026:

• Generated STCs: approximately 90 (system size × deeming period × zone rating)
• Value at $37/STC: $3,330
• This is the “discount” the installer applies to your quote in return for assigning the STCs to them

You don’t see the STC paperwork directly. The installer assigns the STCs to themselves at install, then sells them on the STC market. The “discount” you see on the quote is the value, minus the installer’s margin on the STC trade (typically 5–10%).

What changes for off-grid systems

Off-grid systems don’t generate STCs the same way. Off-grid eligibility is more limited and the STC value is calculated differently. For off-grid installs:

• STCs are still available but at significantly lower values per kW
• Stand-alone Power System (SAPS) accreditation specifically may apply
• Battery storage component is separately calculated
• Many off-grid installs run without STCs because the paperwork burden outweighs the rebate value at small system sizes

For grid-connected systems, the STC rebate is essentially mandatory. For off-grid, it’s a calculation worth running but not a deal-breaker.

Red flags in solar sales

Common patterns that should make you walk away:

• High-pressure sales. “This price is only good today.” Accreditation requires reasonable consumer protection, including a cooling-off period.
• Unbranded “tier 1” claims. Tier 1 isn’t a quality rating; it’s a financial classification by Bloomberg. Real panel quality is judged on warranty, manufacturer reputation, and product specs.
• Cash-only or “off-the-books” pricing. STCs require formal paperwork. A cash-only deal doesn’t qualify for STCs.
• No physical address. Australian Consumer Law requires identifiable trading details.
• Quotes that arrive within 30 minutes of an inquiry. Real quotes require some site assessment, even if just from satellite imagery.
• Promised production figures with no caveats. A quote that says “this system will produce X kWh/year” without context (worst-month, best-month, average) is misleading.
• Inverter brand swap on delivery day. A real concern. Quote specifies one brand, install team substitutes another. This is fraud.

Iron and Air’s position

Iron and Air operates as a licensed Queensland electrical contractor. SAA accreditation is in process. Until SAA issues, grid-connected solar work and battery installation that fall under SAA scope are coordinated through accredited partner installers under one project umbrella. The integration layer (monitoring, automation, network) and all general electrical work is delivered directly by Iron and Air; SAA-required work is delivered by accredited partners, disclosed in writing on every proposal.

When you receive an Iron and Air solar proposal, the partner installer’s accreditation number is listed alongside Iron and Air’s own ABN and licence details. You can verify both before signing.

Common questions

My existing solar was installed under CEC accreditation. Does that affect me? No. Old CEC accreditation was valid at the time of install. STCs already claimed are not retrospectively affected. Only new installs and modifications require SAA-accredited workmanship.

Can a regular electrician install my solar if they’re not SAA-accredited? Technically they can do the work, but you won’t get the STC rebate. Without the rebate, a typical 6.6 kW system costs $3,000–$5,000 more than with it. For nearly all residential cases, the answer is “no, find an SAA-accredited installer.”

What if my installer’s accreditation lapses between quote and install? Their accreditation must be current at the time of install for STCs to be claimable. If it lapses, the install can’t proceed under their accreditation. Check before signing, and consider asking for a clause in the contract addressing this risk.

Is SAA accreditation harder to get than CEC was? The accreditation requirements are similar. The main difference is governance. SAA is intended to be more responsive to consumer complaints and have clearer accountability. Practically, the accredited installer pool is similar to the previous CEC pool, with some installers having dropped out during the transition.
