Solar Panel Brands
We install five panel brands in Perth — and only five. Each one earns its place on a roof for a different reason: outright efficiency, value per watt, heat performance, or warranty backing that will still be answered in 2050.
- Tier 1 brands only
- Australian warranty support
- CEC-accredited installers
- WA-owned since 2018
Solar Panels We Install
Five brands, ranked below by what they’re actually good at. Click through for full specs, datasheets and Perth pricing on each.
Aiko Solar Panels
Highest efficiency
Aiko’s ABC (All Back Contact) cells put every busbar on the rear of the panel, so nothing shades the front. The result is the highest module efficiency you can currently buy in Australia and genuinely better output when a vent pipe or gable throws a shadow across the array.
- Up to 24.2% module efficiency — market leading
- Best-in-class shade tolerance from ABC cell design
- 25-year product and 30-year performance warranty
- Most watts per square metre on a small roof
Jinko Solar Panels
Most installed in WA
The world’s largest panel manufacturer by volume, and the brand we fit most often in Perth. Tiger Neo N-type TOPCon panels sit in the sweet spot — strong efficiency, low degradation, a mature Australian support office, and pricing that makes a 6.6kW system easy to justify.
- Tiger Neo N-type TOPCon, 440–475W
- Australian office and stocked warranty replacements
- 25-year product / 30-year performance warranty
- Best all-round value for a standard Perth home
Trina Solar Panels
Best for tight roofs
Vertex S+ is a compact dual-glass module — smaller and lighter than most 440W panels, which matters when you’re working around a hip roof, a skylight, or an awkward tile run. i-TOPCon cells keep efficiency high and the dual-glass build shrugs off Perth’s salt air and UV.
- Vertex S+ dual glass, 425–450W
- Compact 1762mm frame fits more panels per roof
- Salt-mist and ammonia certified for coastal suburbs
- 25-year product / 30-year performance warranty
Canadian Solar Panels
Best value per watt
Twenty-plus years of manufacturing and one of the lowest cost-per-watt figures we can quote without dropping to a brand we don’t trust. TOPHiKu6 gives you N-type cell technology at a mid-tier price — the right call when the system size matters more than squeezing the last percent of efficiency.
- TOPHiKu6 N-type, 440–460W
- Manufacturing since 2001 — long bankability record
- Lowest cost per watt of the five brands we install
- 25-year product / 30-year performance warranty
REC Solar Panels
Best in Perth heat
Norwegian-engineered HJT panels with a −0.24%/°C temperature coefficient — the number that decides how much output you keep on a 42°C February afternoon. Easy Solar is an approved REC ProTrust installer, so your warranty is backed on both the panel and the installation.
- Alpha Pure HJT cells, 410–430W
- −0.24%/°C — least output lost on hot days
- ProTrust warranty covers panel and installation
- Lead-free build, lowest carbon footprint of the five
Premium or Best Value — Where Each Brand Sits
There is no single best panel. Aiko and REC are the premium end — worth it on a small or shaded roof where every watt counts. Jinko and Canadian Solar deliver more kilowatts for the same spend, which usually generates more electricity over 25 years. Trina sits between the two.

Specifications are for the flagship residential module in each range and change as manufacturers release new versions. We'll confirm the exact model and datasheet on your quote.
How Does Panel Efficiency Actually Work?
Efficiency is the share of the sunlight hitting a panel that comes out as electricity. A 22% panel and a 24% panel both produce the wattage on their label — the difference is how much roof they need to do it.
So efficiency only matters when roof space is the limit. If you have a clear north-facing roof, buying more kilowatts of a mid-tier panel almost always beats buying fewer kilowatts of a premium one.
The number that does matter everywhere in Perth is the temperature coefficient. Panels lose output as they heat up, and roof temperatures here routinely pass 60°C in summer. A −0.24%/°C panel keeps meaningfully more of its rating at that point than a −0.34%/°C one.
Worked example
A 32m² north-facing roof
Aiko at 24.2%
15 panels × 470W = 7.05kW — highest output the roof can physically hold.
Canadian Solar at 22.5%
14 panels × 450W = 6.30kW — around 11% less, at a noticeably lower price.
If the roof isn’t full, spend the difference on more panels. If it is full, spend it on better ones.
Solar Panel Brand FAQs
It depends on your roof. Aiko is the best panel we sell on efficiency, REC on heat performance, Canadian Solar on price, and Jinko is the best all-rounder for a standard Perth home. Tell John your roof size, shading and budget and he’ll narrow it to one or two.
A 25-year warranty is only as good as the company behind it and the installer who lodges the claim. These five all have Australian warranty support and stock we can actually get hold of. We’d rather know five products properly than list forty.
On a small, shaded or complex roof, yes — you can’t add more panels, so each one has to work harder. On a large clear roof, usually not: the same money buys a bigger mid-tier system that generates more over its life.
N-type silicon degrades more slowly, runs cooler and handles low light better than the older P-type PERC cells. Every panel on this page is N-type or HJT — we no longer quote P-type for residential work.
Fifteen 440W panels, or fourteen 470W panels. A 6.6kW system needs roughly 30–34m² of unshaded roof and suits a household using 20–25kWh a day.
No. The rebate is calculated on system size and your postcode zone, not the brand — all five are CEC-approved. See our solar rebate page for current WA figures.
We do. You call John, we lodge the claim with the manufacturer and we do the swap. Our own workmanship warranty runs 10 years on top of the panel warranty.
Not Sure Which Brand? Ask John.
Send your last power bill and a roof photo and we’ll come back with one recommendation and the reason for it — not a five-option price list designed to confuse you. Same-day turnaround for most Perth addresses.
