Solar Panel Installer Questions to Ask in Two Rocks

Two Rocks sits at the northern edge of Perth's solar growth corridor, and more homes here are switching to rooftop power every year. That growth has a downside though. Western Australia's Consumer Protection agency has repeatedly flagged a rise in complaints tied to poor installs, misleading claims, and companies that vanish after taking a deposit. Picking the right Solar Panel Installer is less about finding the cheapest quote and more about asking the right questions before any contract gets signed.
This guide walks through exactly what to ask, in what order, and why each answer matters. It's built for homeowners in Two Rocks and the surrounding northern suburbs, but the same questions apply anywhere in WA.

Why Two Rocks Homeowners Need to Vet Their Solar Panel Installer
Two Rocks gets strong, consistent sun exposure most of the year, which makes it a genuinely good location for solar. That same popularity attracts a mix of experienced local trades and short-lived operators chasing volume. Consumer Protection WA has reported a steady rise in solar-related complaints over recent years, with issues ranging from underperforming panels to installers who become impossible to contact once the job is done.
The fix isn't complicated. A short list of direct questions, asked before signing anything, filters out most of the risk. Homeowners who compare answers across two or three solar panel installers, rather than accepting the first quote, consistently end up with better outcomes and fewer surprises after the crew leaves. Demand for Solar Panel for Western Australian homes keeps rising, and that growth is exactly why a careful selection process matters more now than it did five years ago.
Licensing and Accreditation Questions to Ask a Solar Panel Installer
Every legitimate Solar Service provider in WA should be able to answer these without hesitation:
Are your electricians licensed and working under a licensed electrical contractor? Ask to see the licence itself, not just a business card.
Will I receive an electrical safety certificate for the completed work? This is a legal requirement, not an optional extra.
Are you accredited to install the specific equipment you're quoting? Accreditation for panels and inverters isn't automatic across every product line.
Do your in-house teams do the installation, or is it subcontracted out? Subcontracted jobs can mean less accountability if something goes wrong later.
How long have you operated in Western Australia, and can I see recent local reviews? A company with a short history and no traceable reviews carries more risk if it closes down.

Why This Matters More Than the Price
A cheaper quote from an unlicensed or newly formed operator can end up costing more if the system underperforms or the company disappears. Around 13 percent of solar complaints reported to WA Consumer Protection involved homeowners who simply couldn't get back in touch with the trader or manufacturer once a problem appeared. Verifying licensing and track record up front is the single most effective filter against that outcome.
Equipment and System Design Questions Worth Asking
Once licensing checks out, move to the equipment itself. A generic system rarely performs as well as one designed around the specific roof, shading, and household usage pattern.
Question | Why It Matters |
What brand and tier of panel are you quoting? | Tier 1 panels have stronger manufacturer backing and track record |
What size inverter matches this panel array? | An undersized inverter clips output on sunny days |
Has the system been sized to my actual usage, not just my roof space? | A system that's too small or too large wastes money either way |
Is the system battery-ready for future Battery Storage? | Avoids costly rewiring if a battery gets added later |
Will conduit be run now for future EV Charger Installation? | Cheaper to install during the original job than retrofit |
Residential Solar Panel systems in Two Rocks generally perform best when the installer has actually visited the property rather than quoting from satellite imagery alone. Roof pitch, shading from trees, and orientation all affect real output more than the spec sheet suggests. A rushed solar panel installation booked purely on price rarely accounts for these details properly.

Cost, Contract, and Warranty Questions Before You Sign
This is where most disputes start, and it's also where a careful buyer avoids most of them. Ask for everything in writing, not verbally.
Warranty Type | Typical Length | What It Covers |
Panel performance warranty | Up to 25 years | Guaranteed minimum output over time |
Panel material warranty | 5 to 10 years | Manufacturing defects in the panel itself |
Workmanship guarantee | 5 to 10 years | Installation quality, mounting, and wiring |
Inverter warranty | 5 to 12 years | Inverter failure or performance issues |
Insight: A long panel performance warranty means little if the workmanship guarantee is short or the installer isn't likely to still be trading in five years. Ask specifically who honours each warranty type, the retailer, the installer, or the manufacturer, since WA rules make the retailer responsible for resolving issues rather than passing the homeowner between parties.
Other questions worth confirming before signing:
What's included in the quoted price, and what could add extra cost later, such as switchboard upgrades or meter changes?
Is there a clear start date and completion date written into the contract?
If I was approached at home without an invitation, do I have a cooling-off period before any money is taken?
What happens if the company stops trading before the warranty period ends?

Questions About Battery Storage and EV Charger Installation Add-Ons
Many Two Rocks households are pairing solar with a battery or planning for an EV charger down the track. A capable commercial solar panel installer or residential specialist should be able to answer these clearly:
Does the quoted battery qualify for current state and federal rebates, and has that been calculated accurately?
Can the battery be added later without rewiring, if I'm not ready to buy one now?
What brands of EV charger do you install, and are they compatible with the inverter you're recommending?
Will adding a battery or EV charger later affect my existing panel or inverter warranty?
Getting clear answers here avoids a common and expensive mistake: installing solar now, then discovering the switchboard needs a costly upgrade before a battery or charger can be added.
Red Flags That Mean It's Time to Walk Away
A few warning signs are worth taking seriously, according to WA Consumer Protection guidance and common complaint patterns:
High-pressure sales tactics or a deadline that expires "today only"
Refusal to put verbal promises into the written contract
Vague answers about who holds the electrical licence
No fixed start or completion date offered
Reluctance to provide local references or recent customer contacts
Chart: WA Solar Complaints Reported to Consumer Protection (Year on Year)
2021 ███████████████████████████████████ 57 complaints
2022 ██████████████████████████████████████████ 67 complaints
The upward trend reflects both a growing number of installations across WA and a real increase in reported problems, reinforcing why the questions above are worth the extra ten minutes at quote stage.
FAQs
What questions should I ask before hiring a solar panel installer?
Ask about electrical licensing, accreditation for the specific equipment quoted, warranty lengths for panels and workmanship, and who is responsible if something goes wrong. Also confirm whether the crew doing the work is in-house or subcontracted, since this affects accountability later.
How do I know if a solar installer in WA is legitimate?
Check that their electricians are licensed under a licensed electrical contractor, ask to see the licence, and confirm you'll receive an electrical safety certificate. Reading recent local reviews and confirming how long they've operated in Western Australia also helps.
What warranty should I expect on a solar system in Australia?
Most systems carry a panel performance warranty of up to 25 years, a material warranty of 5 to 10 years, and a workmanship guarantee of 5 to 10 years from the installer. Ask specifically who honours each warranty type before signing.
Can a solar installer pressure me into signing on the spot?
No. WA rules prohibit forceful or high-pressure sales tactics, and if you were approached at home without an invitation, you're entitled to a 10 business day cooling-off period before any money can be taken or installation started.
What happens if my solar company goes out of business?
Your contract is generally with the retailer, so they're responsible for resolving issues, not the manufacturer. If the retailer has closed, you may need to approach the manufacturer directly or seek help through the company's external administrators.
