Solar installer licensing in Perth: what's required and how to verify
Perth solar installers need multiple licences and accreditations to install legally. Understanding what each means helps you choose a genuinely qualified installer, not just one who claims to be.
Perth solar installation legally requires two separate credentials: a current Western Australian (WA) electrical contractor licence for the business, and current Solar Accreditation Australia (SAA) accreditation for whoever designs or installs the system. The Clean Energy Council (CEC) badge many installers still advertise is not the same credential. On WattMate's installer directory, each WattMate Member's profile shows what WattMate has checked under Credentials.
The licensed electrician who does the physical work on your roof operates under that business's licence. The electrician does not hold a personal "contractor" credential. The licence and the accreditation can each be checked in a few minutes on a public register. Skipping those checks is how homeowners end up with an ineligible rebate. It is also how they end up with a system no licensed contractor stands behind. Several overlapping requirements are stacked on top of those two. Some operators lean on the confusion to look compliant when they aren't. Here's what each credential covers and how to check it yourself.
Does a Perth solar installer need a WA electrical licence?
Yes, always. In WA, all electrical installation work, including solar, must be performed by a licensed electrical worker. Building and Energy is a division of the WA Department of Energy, Mines, Industry Regulation and Safety. It registers electrical contractors and workers across the state. It took over the role previously branded EnergySafety WA.
What to check:
- Ask for the company's WA Electrical Contractor Licence number. That licence belongs to the business, not to an individual worker.
- Verify it through Building and Energy's online licence and registration search.
- Confirm the licence is current and classified for electrical contracting work. Also confirm that the person on your roof is a licensed electrician working for that business.
An unlicensed electrician who installs solar in WA is committing an offence under the Electricity (Licensing) Regulations 1991. Insurance claims about installation defects may be void if an unlicensed worker performed the work.
What accreditation does a Perth solar installer need for STCs and DEBS?
Individual solar installers and designers in Australia are accredited by Solar Accreditation Australia (SAA). SAA took over that role from the Clean Energy Council (CEC). The CEC still approves the panels, inverters and batteries themselves. That product-approval register has not changed. The CEC no longer accredits the people doing the work.
Why SAA accreditation matters.
- STCs (Small-scale Technology Certificates). The federal rebate that reduces your quote price is only available for systems installed by an SAA-accredited installer.
- DEBS (Distributed Energy Buyback Scheme). Western Power requires an SAA-accredited designer to sign off on the system design. This happens as part of the Embedded Generation Connection application. You submit that application as the homeowner, or you authorise your installer to lodge it on your behalf.
- WA Battery Incentive: the $130/kWh battery incentive, capped at $1,300, requires the battery to be paired with an inverter approved for DER Storage on Synergy's Supported Solutions List and installed by an SAA-accredited installer.
Two separate schemes sit alongside SAA accreditation.
SAA-accredited installer. The person doing the physical installation. Assessment covers solar photovoltaic (PV) design, electrical safety, and installation standards under AS/NZS 5033 and AS 4777.
NETCC Approved Seller. The company selling the system. The New Energy Tech Consumer Code (NETCC) Approved Seller program is run by the Clean Energy Council. It requires the retailer to provide a compliant installation warranty. It also requires the retailer to use accredited installers.
How to verify:
- Check the installer's SAA accreditation on the Solar Accreditation Australia public register. You can search by name or accreditation number.
- Confirm the accreditation is current. Check its scope too. Some cover PV only; others cover PV plus battery.
- Separately confirm the retailer's NETCC Approved Seller status through the Clean Energy Council's website.
On find installers, each WattMate Member's profile shows what we've checked under Credentials (items marked ‘Sighted by WattMate’ were checked against an official register or sighted by us); everything else there is declared by the installer. Run the checks above yourself either way.
Does battery storage need separate accreditation?
Yes. A PV-only SAA accreditation doesn't cover battery storage installation. An installer quoting on a solar-plus-battery system needs accreditation that specifically covers battery storage.
Ask directly: "Does your accreditation cover battery storage?" Then confirm it on the SAA register, which shows the categories each accreditation covers.
What is the Western Power connection application, and why does installer experience matter?
Every Perth solar system needs an Embedded Generation Connection application before Western Power approves the connection. As the homeowner, you're the responsible applicant. You can authorise your installer or retailer to lodge it for you. An SAA-accredited designer still has to sign off on the system design. It isn't a separate licence.
It is a process that experienced Perth installers handle routinely on their customers' behalf. Newer or unqualified operators sometimes fumble it.
Ask: "How many of these connection applications have you lodged for customers in the past 12 months?" A Perth installer handling residential solar regularly should have lodged dozens. An installer who answers vaguely, or seems unfamiliar with the process, is a warning sign. That is worth taking seriously.
What does "Master Electrician" actually mean?
Some Perth installers advertise membership in Master Electricians Australia (MEA). That is a trade association, not a regulatory licence. MEA members agree to a code of conduct and get access to MEA support. But membership does not substitute for a WA electrical licence or SAA accreditation.
Master Electrician status is a reasonable positive signal. It points to a business with some standing in the industry. Still, verify the electrical licence and SAA accreditation separately. Those are the two credentials the law actually requires.
What about fly-in, fly-out or door-to-door installers?
Perth periodically sees interstate operators running door-to-door campaigns, with crews flown in from the eastern states. Some of these are entirely legitimate. Check three things before you sign. The checks cover the WA electrical licence, the SAA accreditation of the people on site, and who handles warranty claims.
- Is the WA electrical licence current? A company doing electrical work in WA needs a WA electrical contractor licence. An interstate electrical licence does not automatically satisfy that requirement on its own. Confirm the WA licence specifically. Do not assume mutual recognition covers it.
- Who's actually installing it? Confirm the individuals on site hold their own current SAA accreditation, not just the company's.
- Who handles a warranty claim in three years? A company with no ongoing WA presence can be hard to reach for warranty work well after the installation crew has gone home.
Does Perth solar need a building permit?
Usually not. If they comply with standard installation requirements, are mounted on existing roof framing and stay within permitted inverter sizes, residential systems typically don't need a separate building permit beyond the Western Power connection application. Ground-mounted systems and installations that need new structures can require a council building permit. So can some heritage-listed properties.
Your installer should raise permit requirements during the site assessment. If that conversation does not happen and your installation looks like it might need one, ask.
Solar installer verification checklist
Before signing a Perth solar contract, confirm:
- WA Electrical Contractor Licence number obtained and verified through Building and Energy.
- SAA accreditation number obtained and verified on the SAA public register, including current status and scope.
- Battery storage accreditation confirmed, if the quote includes a battery.
- NETCC Approved Seller status checked for the retailer.
- Connection application process discussed, and the installer is clearly familiar with lodging it on your behalf.
- Company has a genuine WA business address, not a fly-in operation.
- Post-installation warranty contact is a WA entity.
