What to Look for in Reliable Solar Installers in Perth: The Essential Checklist

Solar is not a one-night stand, it’s years of relationship built on experience, transparency, and trust. If you’ve ever felt ghosted by a tradie, buckle up because you’re definitely not the only one.

Here’s what reputable installers in Perth offer:

✅ Reputation & Positive Reviews

Before you hand over your hard-earned dollars, do some detective work. Look up installers on independent review sites (Google, Facebook, etc.), not just their own website.

Genuine customer feedback is gold. Ask neighbours, friends or family who’ve installed solar for recommendations. Established, local installers with years in Perth tend to have consistent 4–5 star feedback and CEC/SAA accreditation.

✅ CEC Accreditation & Licensing

Solar is technical and heavily regulated. First, accreditation! Make sure your installer is certified by Solar Accreditation Australia (SAA) for both design and installation. This is the new scheme replacing the old CEC accreditation. SAA accreditation means they’ve passed rigorous training and meet the national standards. It’s mandatory for you to get any federal rebate (STCs).

Likewise, an installer must hold an unrestricted electrical contractor’s licence in Western Australia. After all, solar systems involve high-voltage wiring and must comply with WA’s safety rules.

Beyond that, look for extra badges of trust: many quality companies are members of the Clean Energy Council’s Approved Solar Retailer program or the New Energy Tech Consumer Code (NETCC). These are voluntary codes requiring ethical sales, clear contracts, and solid warranties.

Finally, check that the company actually has a local Perth address or showroom. A genuine local office (or warehouse) means they’re in it for the long haul.

✅ Transparent Quotes & Fair Pricing

A clear, itemised quote is essential. Never sign anything vague or handwritten. Demand a professional breakdown that lists exactly what you’re getting.

A good quote should specify the make and model of each solar panel and inverter, the mounting equipment, labour, monitoring setup (if any), permit fees, and the total system cost including GST. It should even show the value of the small-scale technology (STC) rebate being deducted. This way you can compare offers apples-to-apples, not just by the bottom-line price.

✅ On-Site Assessment

The best installers will insist on visiting your home for a roof inspection before quoting.

Every house is unique. Roof orientation, shading, tile condition and even future plans (like adding an EV or pool pump) affect the ideal system design. When they come out, they should measure your roof, check inverter placement, verify your switchboard, and discuss your power use. If a company tries to give you a binding quote over the phone or email without seeing your roof, move on.

A good installer will also ask smart questions: How much electricity do you use (and plan to use)? Are you thinking of adding major appliances later? They should explain how they size a system and address shading issues.

✅ Panel & Inverter Quality

Not all solar panels and inverters are created equal. You want high-quality, reputable brands that perform reliably in Perth’s harsh sun and heat. Insist your installer names the panel and inverter models.

Prefer Tier-1, high-efficiency panels and inverters known for reliability in WA’s climate Demand exact model numbers for both panels and inverters, and to verify that they appear on the official approved products list. Only CEC/SAA-approved panels and inverters can earn you the federal rebate, so this check is crucial.

✅ Strong Warranties & Guarantees

Your warranty is your safety net. Make sure you clearly understand what’s covered and for how long - and get it in writing. There are usually three warranties to check:

Crucially, ask who handles warranty claims. Some installers pledge to manage the claim on your behalf (liaising with manufacturers), while others might ask you to deal with the foreign manufacturer directly.

✅ After-Install Support, Monitoring, & Maintenance

A professional installer’s job isn’t done when the final panel is bolted down. Ask what kind of post-installation support they provide. Do they offer a monitoring platform so you can track your system’s performance? Will they help you troubleshoot if something seems off?

Good questions to ask:

Who is your go-to contact for problems?

What’s their typical response time for service calls?

Will they do any scheduled check-ups?

Some companies even offer maintenance contracts or performance guarantees. In any case, you want an installer who stands by their work and will be easy to reach if an inverter alarm or panel fault pops up.

✅ WA Battery Rebates & VPP Readiness (for Storage)

If you’re eyeing a home battery under WA’s rebate scheme, this step is critical. The WA Residential Battery Scheme requires that any eligible battery system be part of a Virtual Power Plant (VPP). This means your battery must be on the approved equipment lists (CEC clean energy council battery list, Synergy/Horizon supported solutions) and able to connect to a VPP network.

When talking to installers, ask if the battery they offer is VPP-capable. Also confirm they will handle all the paperwork as under the WA scheme, your battery vendor submits the rebate application on your behalf. Make sure they’re on the official approved vendor list, and that the products they propose are on the CEC/Synergy/Horizon approved lists.

In short: to get the WA battery rebate, ensure your installer makes your system VPP-ready and deals with the paperwork.

In the end, the most reliable solar installers in Perth are those who meet every one of these criteria. Pick a partner who’s upfront, experienced, and has your back for years to come, and you’ll be reaping the sunshine and savings well into the future.

Questions to Ask a Solar Installer Before You Sign Anything

Don’t get pressured! These questions reveal the truth. Before you ink any deal, make sure you get clear answers to these critical questions:

✅ Are the solar panels and components CEC approved?

Ask if the panels, inverter, system designer, and installer are Clean Energy Council (CEC) or Solar Accreditation Australia (SAA) approved. Proper accreditation is required for government rebates and grid connection in Australia.

✅ Are you a WA battery rebate approved installer?

Western Australia’s battery rebate program requires the installer to be on the approved vendor list, otherwise, you can’t claim the rebate. A reputable installer will apply for the rebate on your behalf and guide you through the process.

To learn more, see our in-depth guide: WA Residential Battery Rebate Scheme 2025.

✅ Do you handle the installation with your own team or subcontract?

This is where the cowboys reveal themselves. If the installer uses subcontractors, you risk inconsistent workmanship, mixed accountability, and zero after-care.

✅ Will I receive live data access on my phone after installation?

Non-negotiable. You should be able to track your solar production and battery storage in real time via a monitoring app installed before the installer leaves.

✅ If something goes wrong, who’s responsible for repair or replacement costs?

Warranties can be confusing, so get specific:

Most manufacturers do not cover labour costs. Make sure your installer offers a workmanship or service warranty so you aren’t stuck paying labour later.

✅ Who will submit the application for the grid connection?

In Perth, your system must be approved by Western Power and Synergy/Horizon Power.
A reputable installer will manage it for you, including all paperwork and approvals. If they tell you to figure it out yourself… run.

✅ What’s the warranty on the solar system?

Get all warranty terms in writing. As a rule of thumb:

FAQs

Q1: How do I find a trusted solar installer in Perth?

Verify local experience, CEC/SAA accreditation, a physical Perth office and independent reviews. Ask for references, an itemised quote and a site visit — and compare multiple quotes that use the same scope.

Q2: What accreditation should a solar installer have?

Choose installers with Clean Energy Council (CEC) or current Solar Accreditation Australia (SAA) accreditation, plus a valid electrical contractor licence in WA. Always ask for accreditation numbers and verify them online.

Q3: Do I need a WA battery rebate approved installer?

Yes — the WA scheme requires an approved vendor to apply for the rebate on your behalf. Use an approved installer (like Renostain) to secure state and federal battery incentives and to manage VPP enrolment.

Q4: How do I avoid getting ghosted by a solar installer?

Do your homework: meet at their office, check accreditation and reviews, insist on a signed contract with milestones and warranty details, and avoid full upfront payments. If they pressure you, walk away.

Q5: How can I check if a solar company is legit?

Confirm ABN/office address, CEC/SAA accreditation, itemised quotes, warranty terms (panel, inverter, workmanship) and independent reviews. Local referrals and transparent paperwork are strong legitimacy signals.

Q6: What should I expect in a professional solar quote?

A professional quote is itemised: panel & inverter brands, system size (kW), expected output, installation inclusions, lead times, fees, and warranty details. If it’s vague or “from $…”, ask for clarification or another quote.

Q7: How do I check if an installer is accredited?

To check if a solar installer is accredited, ask for their Solar Accreditation Australia (SAA) number and verify it on the SAA website. When they arrive, look for their digital ID card with photo and accreditation details. Also, make sure they hold a valid electrical licence for safe and compliant installation.
