Best solar installers in Stirling, Osborne Park & Scarborough (2026)
Table of Contents
The City of Stirling has the densest concentration of solar businesses in Perth, and the Osborne Park light industrial estate is the reason why. Howe Street, Leeway Court and Pitino Court sit within a few hundred metres of each other and between them hold three of the four operators on this page. That density cuts both ways: it means real warehouses and real crews, but it also means a lot of trading names sharing a suburb without sharing a standard. We ranked on the New Energy Tech Consumer Code register first and the Google score second, which is the only order that makes sense for work that is legally electrical work.
Featured installers
This slot is reserved for a Blue Collar Business member operating in Stirling, Osborne Park, Balcatta or Scarborough. It is a paid placement, it sits outside the ranking below, and we label it every time so you always know which is which.
Get a Featured spot ▸Positive Energy Solutions
Four hundred and thirty reviews at 4.9 is the strongest combination of rating and volume anywhere in the Stirling corridor, and the register backs it up: Positive Energy Solutions has been a signatory to the New Energy Tech Consumer Code or its ACCC-authorised predecessor since May 2021, which puts it among the longer-standing approved sellers in Western Australia. Its register entry lists Western Australia as its only region of operation, and the head office address on the register, Level 1 at 59 Howe Street in Osborne Park, matches its Google listing exactly. That kind of agreement between an independent national register and a Google pin is the single cleanest locality signal we get, and it is rarer in solar than you would expect. The register also records solar PV, energy storage and EV charging, so a battery or a charger added later does not mean finding a second contractor. The weighted score of 4.8245 is the highest on this page by a clear margin, and unlike most leaders in this trade the gap is driven by volume rather than a small number of perfect reviews.
Claim or update this listing ▸Australis Solar
Australis Solar is the only operator on this page with two addresses inside the cluster, and both of them come from the NETCC register rather than from a marketing page. The head office is Unit 5 at 1 Pitino Court in Osborne Park and the register separately lists a Western Australian branch at 169A Scarborough Beach Road in Scarborough. That matters for a coastal job: Scarborough, Trigg and North Beach roofs get salt exposure that inland Balcatta roofs do not, and an operator with a branch on the coast has a shorter callback trip. Its signatory date of 16 November 2018 is under the predecessor ACCC-authorised code, meaning it has been operating under an external consumer-protection standard for roughly seven years. At 4.9 across 153 reviews the weighted score lands at 4.7419, a genuinely small distance behind first place. If your job is in Scarborough or Innaloo rather than Osborne Park proper, this is arguably the more practical first call.
Claim or update this listing ▸Solahart Balcatta
A clean 5.0 across 41 reviews with a Balcatta workshop at 1A/8 Booth Place, listed at that address on the NETCC register as well as on Google. Solahart is a franchise network, which means the brand tells you nothing on its own: each dealer is separately assessed, and we have already found northern-corridor Solahart dealers that do not appear on the register at all. This one does, with a signatory date of 16 June 2025. That date is recent, so the code obligations are newer here than at the two operators above it, and the weighted score of 4.6454 reflects a review count that is still building rather than any complaint pattern. Worth noting for anyone weighing hot water against panels: Solahart dealers typically carry solar hot water alongside PV, which is a different conversation from the panel-and-battery pitch you will get elsewhere on this page, and occasionally the better answer for a household with high water use.
Claim or update this listing ▸Clean NRG Solar
The longest register history of any operator in this cluster, by a wide margin: Clean NRG Solar has been a signatory since 26 March 2015, roughly eight years before the New Energy Tech Consumer Code replaced the Approved Solar Retailer program it started under. Eleven years of continuous participation in an ACCC-authorised code is a meaningful signal in a trade with a long history of operators trading briefly and disappearing. Its Osborne Park address at 1/7 Leeway Court appears twice on the register, as both head office and Western Australian branch, and matches Google. At 4.8 across 91 reviews the weighted score is 4.6429, which places it fourth here by the narrowest margin on the page, twenty-five ten-thousandths behind Solahart Balcatta. Treat positions three and four as a tie in practice and choose on which one answers the phone and turns up to quote.

Every business on this page had to clear the credential gate before its Google score was even calculated. We searched the New Energy Tech Consumer Code Approved Seller register by name for each candidate and kept only the ones that returned a match with a Western Australian address. That filter removed several operators with better raw ratings than the ones we ranked, including a 5.0 with 326 reviews at a Perth CBD address and a 5.0 with 27 reviews on Scarborough Beach Road. It is a deliberately harsh filter and we would rather publish four verified operators than eight unverified ones. After the gate, we score with a weighted formula that pulls low-volume ratings toward the trade average, so a perfect 5.0 from nine reviews cannot outrank a 4.9 from four hundred. Addresses were confirmed against the Google place page rather than the search result card, because the category label on a search card in this trade is wrong often enough to be useless.
What a WA solar installer must actually hold
Solar is not a general trade. Grid-connected rooftop solar is electrical installing work, and three separate requirements stack on top of each other. Most homeowners only ever hear about the third one, which is the weakest of the three.
- A Western Australian electrical contractor’s licence, held by the business. Under the Electricity (Licensing) Regulations 1991, electrical work in WA may only be carried out by a person holding the appropriate electrical worker’s licence, and electrical installing work must be carried out by a licensed electrical contractor who employs licensed electricians. A solar company without a contractor’s licence of its own must engage one. Building and Energy at the Department of Energy, Mines, Industry Regulation and Safety administers this.
- Solar Accreditation Australia accreditation, held by the individual installer and designer. The Clean Energy Regulator requires that a small-scale system be designed and installed by an SAA-accredited designer and installer to be eligible for small-scale technology certificates. SAA replaced the Clean Energy Council as the accreditation scheme operator in 2024 and the CEC’s accreditation services have ceased.
- An unrestricted electrical licence in the state of installation. The Clean Energy Regulator states that accredited installers must also hold an unrestricted electrical licence in the state or territory where the system is installed. A restricted licence is not enough for grid-connected work.
- New Energy Tech Consumer Code approval, held by the retailer. This one is voluntary. It is ACCC-authorised and administered by the Clean Energy Council, and it covers sales conduct, contracts, deposits and complaint handling rather than technical competence. It replaced the Approved Solar Retailer program in February 2023.
- A written compliance statement at handover. The Regulator requires the installer and designer to confirm in writing that accredited design and installation requirements were met, that local and state requirements were met, and that a licensed electrician completed the work and provided their accreditation details.
The schemes that change what you actually pay
We do not publish price estimates for solar because we cannot verify them, and a number invented for a page like this would be worse than no number at all. What we can verify is the scheme framework, because it is published by the bodies that run it. The table below is drawn from Synergy and the Clean Energy Regulator directly, checked on the date shown at the foot of this page. Rates are not listed here because they are reviewed annually and any figure we printed would date.
| Scheme | Who runs it | What it changes for you |
|---|---|---|
| Small-scale technology certificates | Federal | Reduces the upfront cost, but only if the design and install are SAA-accredited |
| Distributed Energy Buyback Scheme | WA | Pays a credit for exported electricity on new and upgraded systems |
| Renewable Energy Buyback Scheme | WA | The older scheme, closed to new systems but existing customers may stay on it |
| Battery technical requirements | WA | From 1 May 2026, new and upgraded battery systems up to 30 kVA must comply |
| NETCC approval | National | Sets sales, contract and complaint-handling standards, and it is voluntary |
DEBS was launched by the State Government on 31 August 2020 and replaced REBS for eligible new and upgraded systems. Synergy states it is available to households, schools, educational institutions and not-for-profits in WA who are installing a new eligible system, upgrading an existing one, moving into a property with an existing system, or switching across from REBS. Existing REBS customers may choose to stay on REBS subject to its terms.
What we cut from this ranking, and why
- Fritts Solar, 5.0 from 326 reviews. The best raw record in the whole sweep, and cut twice over. Its Google address is Level 25 at 108 St Georges Terrace, a Perth CBD tower rather than a Stirling workshop, and a name search of the NETCC register returned no match. We would revisit it immediately if either changed.
- Solar Repairs Perth, 4.4 from 277 reviews. A real Balcatta address at 15 Delawney Street and a substantial review history, but no match on the NETCC register when searched by name. Cut on the credential gate alone.
- Aus Energy Solar, 4.8 from 305 reviews. Passes the credential gate cleanly, a signatory since 18 June 2025 operating across four states. Cut on locality only: its Google address is Mount Hawthorn and its register head office is Subiaco, both outside the City of Stirling. We will not stretch a cluster boundary to import a good operator.
- Fusion Sun Solar, 5.0 from 27 reviews, and Advanced Solar Technology, 4.7 from 28 reviews. Both hold genuine addresses inside the cluster, on Scarborough Beach Road and Mumford Place respectively. Neither returned a NETCC register match. Re-check next cycle.
- MaxSolar 5.0 from 117 reviews, SMC Energy 4.8 from 19, Mt Solar WA 5.0 from 39 and Clean Solar Planet 5.0 from 21. No verifiable street address between them. MaxSolar in particular is a large stranded record and the strongest paid-placement target in this corridor.
- PV Spark, SolarGrid Perth, Perth Solar Force and Solaire Connect. All real operators, all outside this cluster. PV Spark is Malaga, SolarGrid Perth is on Bulwer Street, and the last two are Wangara and Landsdale businesses already ranked on our Joondalup and northern suburbs page.
Questions to ask before you sign
- Who holds the electrical contractor’s licence? If the salesperson cannot name the licensed contractor doing the work, you are talking to a reseller rather than an installer, and you need to know that before you sign.
- Will the SAA-accredited installer be physically on site? On-site attendance is an accreditation requirement, not an optional extra, and it is the single most common failure point in the trade.
- Is the quoted price before or after the certificate discount? Small-scale technology certificates are usually assigned to the retailer and shown as an upfront discount, so a headline price can mean two very different things.
- Am I moving from REBS to DEBS, and do I want to? Upgrading an existing system can change your buyback arrangement. Ask before the quote is signed, not after the meter is reconfigured.
- If I add a battery, does it meet the requirements that apply from 1 May 2026? New and upgraded battery systems up to 30 kVA must comply with the WA Government technical requirements from that date.
Signs of a poor operator
- A price that expires today. Deposit pressure and same-day discounts are exactly the conduct the consumer code exists to constrain, and an approved seller has agreed not to do it.
- No physical address, only a phone number and a service-area map. Four of the businesses we assessed for this page have no address anywhere, one of them carrying 117 reviews. That is a warranty problem waiting to happen.
- Vagueness about which brand of panel and inverter you are actually getting. A quote that names a wattage but not a manufacturer lets the specification move between signing and installation.
- An installer who has never mentioned accreditation. If nobody has raised SAA accreditation or the electrical contractor’s licence by the time you are being asked for a deposit, raise it yourself.
- Reviews that all landed in the same fortnight. Check the distribution over time, not just the average. A genuine eleven-year operator has a long tail of reviews, not a spike.
Common questions
Do I need an accredited installer, or is a licensed electrician enough?
You need both, and they are separate things. The electrical licence is a Western Australian requirement administered by Building and Energy, and it is what makes the work lawful: under the Electricity (Licensing) Regulations 1991 electrical installing work must be done by a licensed electrical contractor employing licensed electricians. Accreditation from Solar Accreditation Australia is a federal requirement that sits on top of it, and it is what makes the system eligible for small-scale technology certificates. The Clean Energy Regulator is explicit that accredited installers must also hold an unrestricted electrical licence in the state of installation. So a licensed electrician without SAA accreditation can wire your house but cannot give you a certificate-eligible solar installation, and an accredited installer without an unrestricted WA licence cannot lawfully do the work here at all.
What is the New Energy Tech Consumer Code and does it actually mean anything?
It is a voluntary code, authorised by the ACCC and administered by the Clean Energy Council, that covers how solar is sold rather than how it is installed. Approved Sellers commit to standards on advertising, sales conduct, contracts, deposits, warranties and complaint handling. It replaced the Approved Solar Retailer program in February 2023, and sellers with a signatory date before then were participants in that earlier ACCC-authorised code. What it does not do is certify technical competence, which is what accreditation and licensing are for. We use it as our first filter for a practical reason rather than a philosophical one: it is the only register in this trade that can actually be searched by business name, and it returns street addresses, which doubles as a locality check.
How do I check a WA electrical contractor’s licence myself?
Through the WA Online Licence Search operated by the Department of Energy, Mines, Industry Regulation and Safety. Be warned that it is a number-only search: it requires an exact licence number with the correct prefix and will not accept a business name. In practice that means you have to ask the operator for its electrical contractor’s licence number and then verify that number, rather than looking the company up cold. Any legitimate contractor will give you the number without hesitation. If you are quoted by a business that will not provide one, that refusal is your answer.
What does DEBS pay, and am I eligible?
We do not publish the rate because Synergy and Horizon Power review it annually and any figure printed here would date. Check the current DEBS pricing schedule on your retailer’s site. On eligibility, Synergy states DEBS is open to households, schools, educational institutions and not-for-profits in Western Australia who are installing a new eligible renewable or distributed energy system, upgrading an existing one, moving into a property that already has one, or switching over from REBS. All systems must be eligible under the DEBS terms and conditions, so confirm your specific system with your retailer before you commit to a design.
I already have solar. Does adding a battery change my buyback arrangement?
It can, and this is the detail that catches people out. DEBS replaced REBS for eligible new and upgraded systems, and adding a battery is an upgrade. Existing REBS customers may choose to stay on REBS subject to its terms and conditions, but an upgrade is exactly the trigger point where the question arises, so raise it with your retailer before the work is scheduled rather than after. Separately, from 1 May 2026 all new and upgraded household and small business rooftop solar battery systems installed up to 30 kVA must comply with new WA Government technical requirements, so a battery added now is not specified the same way one added two years ago was.
Why is a company with 326 reviews and a perfect score not on this list?
Because it failed both of our filters rather than either one. Fritts Solar carries a 5.0 across 326 reviews, which on raw numbers would top this page comfortably. Its listed address is a Perth CBD tower rather than a premises in the City of Stirling, so it fails the locality test for a Stirling cluster, and a name search of the NETCC Approved Seller register returned no match, so it fails the credential gate as well. Neither of those is an accusation about the quality of its work, and we say so plainly. It means we could not verify what we require before ranking a business, and we would rather show you four operators we could verify than pad the list.
