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, not one. The business carrying out the electrical work needs a current WA electrical contractor licence, and the licensed electrician who does the physical work on your roof operates under that business's licence rather than holding a personal "contractor" credential. Separately, whoever designs or installs the actual system needs current accreditation from Solar Accreditation Australia (SAA), not the Clean Energy Council (CEC) badge many installers still advertise. Both are checked in a few minutes on a public register, and skipping that check is how homeowners end up with an ineligible rebate, or a system no licensed contractor stands behind.
The industry has several overlapping requirements stacked on top of those two, and 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, the WA Department of Energy, Mines, Industry Regulation and Safety division that took over the role previously branded EnergySafety WA, registers electrical contractors and workers across the state.
What to check:
- Ask for the company's WA Electrical Contractor Licence number, since 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, and that the person on your roof is a licensed electrician working for that business.
An unlicensed electrician installing solar in WA is committing an offence under the Electricity (Licensing) Regulations 1991. Insurance claims relating to installation defects may be void if the work was performed by an unlicensed worker.
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), which took over that role from the Clean Energy Council. The CEC still approves the panels, inverters and batteries themselves, that product-approval register hasn't changed, but it no longer accredits the people doing the work.
Why SAA accreditation matters:
- STCs: the federal rebate that reduces your quote price is only available for systems installed by an SAA-accredited installer.
- DEBS: Western Power requires an SAA-accredited designer to sign off on the system design as part of the Embedded Generation Connection application, which you as the homeowner submit, or authorise your installer to lodge 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 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 Approved Seller program, administered by the Clean Energy Council, requires the retailer to provide a compliant installation warranty and use accredited installers.
How to verify:
- Check the installer's SAA accreditation on the Solar Accreditation Australia public register, by name or accreditation number.
- Confirm the accreditation is current, and check its scope. 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.
For a shortcut, the installers listed on find installers have these credentials verified up front.
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, though you can authorise your installer or retailer to lodge it for you, and an SAA-accredited designer still has to sign off on the system design. It isn't a separate licence. It's a process that experienced Perth installers handle routinely on their customers' behalf, and one that newer or unqualified operators sometimes fumble.
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 worth taking seriously.
What does "Master Electrician" actually mean?
Some Perth installers advertise membership in Master Electricians Australia (MEA). That's a trade association, not a regulatory licence. MEA members agree to a code of conduct and get access to MEA support, but membership doesn't 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. Verify the electrical licence and SAA accreditation separately regardless, 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, installing with crews flown in from the eastern states. Some of these are entirely legitimate. Check three things before you sign:
- Is the WA electrical licence current? A company doing electrical work in WA needs a WA electrical contractor licence. An interstate electrical licence doesn't automatically satisfy that requirement on its own, so confirm the WA licence specifically rather than assuming 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. Residential systems that comply with standard installation requirements, mounted on existing roof framing and within permitted inverter sizes, typically don't need a separate building permit on top of the Western Power connection application. Ground-mounted systems, installations needing new structures, and some heritage-listed properties can require a council building permit.
Your installer should raise permit requirements during the site assessment. If that conversation doesn't 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
