SAA accreditation for Perth solar installers: why it matters

If a Perth installer isn't SAA-accredited, you don't get your STC rebate and you don't get Synergy's DEBS export credits. That's why nearly every installer's brochure says "SAA-accredited", and why it's quick to check before you sign.

What is SAA accreditation?

Solar Accreditation Australia (SAA) accredits solar installers and designers one person at a time. It sits alongside a normal electrician's licence and doesn't replace it. Not every licensed electrician holds it, because it needs its own solar training and assessment.

The person holding it (the installer, or the supervising licensee at the company) has finished nationally recognised training in solar PV design and installation. They've shown they know the wiring rules in AS/NZS 3000 and the grid-connected inverter rules in AS4777.2. They also hold a current WA electrical contractor's licence, which the law requires for any electrical work here. And they keep up annual professional development to stay on the register.

Why you can't get STCs or DEBS without it

Two of the incentives that pay a Perth household back, the upfront STC rebate and the export credits, depend on an SAA-accredited installation.

The federal STC rebate takes roughly $1,400–$3,600 off your upfront cost, depending on system size and zone. It only applies if an SAA-accredited installer or supervisor designs and installs the system. A non-accredited job gets no STCs at all.

Synergy's DEBS (Distributed Energy Buyback Scheme) works the same way. Synergy only grants export credits on a system installed by an SAA-accredited installer, and the Western Power network connection approval (NCN) has to be in place too. Skip either and the system can't access DEBS.

In practice, a genuine Perth installer can't afford to work outside accreditation, because customers would lose the rebate and wouldn't buy. Checking is still worth it, especially when one quote comes in suspiciously cheap.

How do I check an installer is accredited?

SAA keeps a public register. Go to saaustralia.com.au, use the installer search, and look up the company or the specific installer's name. The entry shows their status and expiry date.

You want to see "accredited", not "expired" or "suspended". The accreditation should cover solar PV, since some are for solar hot water only. And it should be in the name of the supervising installer at the company, not just a generic company listing.

If an accreditation has expired or isn't on the register at all, treat that as a serious red flag. Genuine installers keep it current, because losing it means losing access to STC processing.

Accreditation is one of several credentials a Perth installer needs. Our solar installer licensing guide covers the WA electrical licence side. On find installers, each WattMate Member's profile has a Credentials section. Items marked ‘Sighted by WattMate’ were checked against an official register or sighted by us. Everything else there is declared by the installer.

Is "NETCC Approved Seller" the same thing?

No, and people mix them up all the time. They're two different designations from two different bodies.

SAA accreditation is about the person doing the physical installation. It's the mandatory one, required for STCs and DEBS.

NETCC Approved Seller is about the business. It means the company has signed the New Energy Tech Consumer Code. The Clean Energy Council (CEC) has administered that code since 2023, when it replaced the older CEC Approved Solar Retailer scheme. Signing is voluntary. What it does is hold the business to a written standard on sales conduct, product claims and complaint handling.

You'll find companies that are both, and companies that employ SAA-accredited installers without being NETCC Approved Sellers.

Installer or designer: who signs off what?

Larger systems, typically over 10kW, need an SAA-accredited designer to certify the design, separate from the accredited installer doing the work. On a standard 6.6–13.3kW home system, one person typically holds both accreditations and covers both roles. On commercial or complex residential projects the roles may be separate.

When you read a quote, look for who the accredited installer is, since they must supervise the physical work, and who signed off the design, since they must be SAA-accredited for that system size.

What else does WA require on top of SAA?

SAA is a national standard, but electrical work in WA also has to meet state rules. The company doing the work needs a WA electrical contractor's licence (through the Electrical Licensing Board, ELB). Afterwards, the licensed electrician sends an Electrical Certificate of Compliance (ECC) to Western Power. And the grid connection needs NCN approval from Western Power.

An SAA-accredited installer from another state can't legally install solar here without a WA licence. So confirm they're licensed in WA too. National accreditation alone isn't enough.

What are the red flags?

Start with the quote itself. A genuine one includes an "STC assignment" showing the rebate is built into the price. If there's no mention of it, the installer may not be accredited, or the quote may simply leave the rebate out. Either is unusual and worth asking about.

Price is the next giveaway.

If one quote sits 40% below the others with no explanation, it may mean lower-quality panels, unlicensed labour or no STC processing.

Then watch how they react to questions. Any genuine installer will happily give you their accreditation number to verify, so resistance is a bad sign. The same goes for the NCN: a real Perth installer will explain the process and timeline and handle the application for you, and dodging the topic is a concern.

The product side of the same check is in our CEC Approved Products List guide, which shows how to verify panels, inverters and batteries against the CEC lists.
