Australian-made solar available in WA by Perth Solar Warehouse

Western Australian homeowners have long trusted Perth Solar Warehouse for reliable, high-quality solar solutions. Today, we’re excited to share one of our most significant announcements yet—one that strengthens local manufacturing, boosts supply security, and gives WA families access to some of the most rigorously built solar panels in the country.

Beginning in 2026, Perth Solar Warehouse will offer Australian-made Tindo solar panels as part of our product lineup.

As Director Derek McKercher shared when announcing the partnership on LinkedIn:
“I’m bringing Australian-made solar panels to Western Australia.”

And we couldn’t be prouder to do exactly that.

Tindo panels stand out because they’re designed and manufactured specifically for Australian conditions, built locally under some of the strictest quality standards in the world. Unlike many imported alternatives, these panels undergo controlled, transparent, Australian-based production processes that ensure exceptional durability and performance, even in WA’s harsh summer heat and coastal environments. For homeowners, this translates directly into long-term reliability and the confidence that your solar investment is built for our climate rather than adapted to it.

Just as important are the warranties and performance guarantees behind the product. Tindo panels offer a locally backed 25-year product warranty and a strong long-term power output guarantee, underscoring their durability and expected lifespan. With support handled here in Australia rather than offshore, homeowners also benefit from quicker, more responsive service throughout the life of the system. These protections give families the peace of mind they deserve when making a significant energy decision.

The move to introduce Australian-made solar panels also represents a major leap forward for supply chain security in Western Australia. In recent years, global disruptions have affected solar availability worldwide. By partnering with a domestic manufacturer, we’re ensuring a more stable and predictable supply of premium panels, reducing the risks of shipping delays, shortages, or sudden market fluctuations. It’s a shift that not only supports Australian jobs and industry but also directly benefits WA families planning ahead for a reliable solar installation.

With over 20 years of local energy expertise, Perth Solar Warehouse has consistently provided homeowners with reliable and well-supported solar solutions. By incorporating Tindo into our offerings, we align perfectly with our mission to deliver quality installations backed by products we truly trust. This partnership not only expands our range but also represents a significant step toward offering better local choices, higher standards, and long-term confidence for residential customers throughout the state.

Tindo solar panels will be available starting in 2026 through Perth Solar Warehouse. We encourage homeowners who value Australian manufacturing, strong warranties, and reliable supply security to begin exploring their options now. If you’re interested in learning more or want to register your interest ahead of the launch, our team is here to assist you every step of the way. Together, we can support Australian innovation while providing Western Australian homes with quality you can rely on.

Sigenergy voluntary product recall explained for concerned customers

Affected Sigen Energy Controller under the Sigenergy Voluntary Product recall highlighted representing the affected component within the stack

In October 2025, Perth Solar Warehouse’s parent company, McKercher Corporation, published the details of a Product Change Notice for Sigenergy SigenStor EC and Sigen Hybrid inverters, addressing improvements to the AC output interface. Due to further field observations and consultations with regulatory bodies, this notice has escalated to a voluntary product recall affecting specific single-phase models distributed throughout Australia.

The recall, initiated by Sigenergy Technology Co., Ltd., is being conducted under the supervision of the Australian Competition and Consumer Commission (ACCC), with support from the Clean Energy Council (CEC), the Clean Energy Regulator, and state-based electrical authorities.

Sigenergy has identified isolated occurrences of damaged AC plugs on certain 8 kW, 10 kW, and 12 kW single-phase Sigen Energy Controllers/Inverters. While the issue originates from incorrect installation practices rather than a product defect, the company has opted for a voluntary national replacement program to ensure the highest standards of safety and reliability.

This measure follows Sigenergy’s proactive engineering response and firmware updates designed to safeguard system performance while replacement units are distributed.

Models Affected

Single-Phase (SP) – 8 – 12 kW

SigenStor EC 8.0 SP / 10.0 SP / 12.0 SP
Sigen Hybrid 8.0 SP / 10.0 SP / 12.0 SP

Note: No three-phase models are affected.

Affected units can be identified by production before October 2025 and may lack the green-dot packaging mark introduced with the updated AC plug design.

Sigenergy is initiating a voluntary product recall due to issues with the sensitivity of the AC plug connection, which is linked to improper installation methods. The original design of the plug required the use of ferrules and crimping to create a stable electrical connection. If these steps were either omitted or incorrectly executed, it could lead to localised heating and mechanical degradation of the plug during prolonged high-power use.

Although there is no systemic defect with the product, Sigenergy has redesigned the AC plug to align with the three-phase connector system. This new design eliminates the need for ferrules or crimping, ensuring consistent installation quality and reducing the chances of variations in the field.

Firmware Safeguard: All installed 8–12 kW single-phase models have received a firmware update enabling real-time monitoring and temporary power reduction during high-load conditions. This ensures continued safe operation until hardware replacement.

New AC Plug Design: A ferrule-free, pre-moulded connector has been introduced to standardise installation practices and prevent overheating risks.

Verification: Regulatory bodies have confirmed that the inverters remain compliant when installed according to manufacturer instructions.

The Sigenergy voluntary product recall is being undertaken as a precautionary safety initiative.

For homeowners:

Safe to Operate: Your system remains operational and safe under the firmware safeguard.
Replacement at No Cost: Sigenergy will replace affected inverters free of charge, including installation.
Extended Warranty: Each replaced unit receives an additional 2-year warranty.
No Action Required: Customers will be contacted directly to schedule their replacement through Sigenergy’s service network or Perth Solar Warehouse.

For installers:

Check Model & Serial Number: Verify if installed single-phase units fall within the 8–12 kW range delivered prior to October 2025.
Replacement process: Perth Solar Warehouse will perform replacements for our affected customers, Q1 2026.
Stop Use of Previous Versions: The previous AC plug version must no longer be installed in Australia.

The Sigenergy voluntary product recall is conducted in coordination with the ACCC’s Product Safety Australia, the Clean Energy Regulator, and the Clean Energy Council. Authorities have verified that the recall addresses installation-related concerns only and maintains the Sigenergy range’s eligibility for Battery Small-Scale Technology Certificates (BSTCs).

New and replacement SigenStor EC and Sigen Hybrid single-phase inverters can be identified by:

Green dot marking on the outer packaging label, and
Revised product documentation noting the “Updated AC Plug (OT-type)” connection.

For further clarification, please contact: service@sigenergy.com

Alternatively, Perth Solar Warehouse customers and installers may contact the PSW technical support team for assistance regarding scheduling or documentation.

Perth Solar Warehouse and Sigenergy remain committed to engineering excellence, safety, and customer confidence. This voluntary recall demonstrates the shared priority of maintaining the integrity, reliability, and compliance of all Sigenergy systems operating across Western Australia.

To date, there are no recorded occurrences of Sigenergy AC plug failures in Western Australia. This is widely attributed to a more conservative grid operation under VPP conditions.

Our responsibility is to minimise PSW customer exposure to this minor interruption in Sigenergy supply.

If my installation occurs in 2026, is there a change in my out-of-pocket system costs?

No.

PSW customers with a delayed installation date affected by the Sigenergy voluntary product recall will not in-cure additional expense if affected by the subsidy reduction.

Can the old version still be installed?

No.

Under the Sigenergy voluntary product recall, the previous version Inverter/Energy Controller models of single-phase (8, 10, 12 kW) must no longer be used in Australia.

When am I likely to be be re-scheduled to?

We’ll touch base with affected PSW customers for an ideal revised installation date in Q1 2026.

Please note: alternative Australian geographic regions receive stock at different times. Stock prioritisation will most likely be in order of highest demand Australian regions.

Clean Energy Regulator report ›

Will the new models remain eligible for BSTCs (battery rebate)?

Yes.

A product recall would make Sigenergy ineligible to further claiming BSTC’s. However, Sigenergy is conducting a voluntary product recall, which is being overseen by the ACCC’s Product Safety Australia to aid consumer confidence appeasing the CEC product listing requirements.

Can I still operate my Sigenergy single-phase 8, 10 or 12 kW inverter if installed already?

Yes.

Sigenergy has already remotely output limited supply of your 8, 10 or 12 kW Sigen Energy Controller in high-current scenarios through an over the air update. This method ensures time under safe lower-current operating conditions while all parties address the Sigenergy voluntary product recall.

We’ll touch base with affected PSW customers for an ideal replacement date in Q1 2026.

The ideal LONGi solar panels for Perth homes

LONGi is one of the world’s largest solar panel manufacturers by shipped volume. That scale alone doesn’t tell you whether their panels are a good fit for your roof. What does: the technology inside, how it performs in Perth’s climate, and what warranty protects it when you’re not watching.

This guide covers the LONGi panels that actually matter for residential installations in Western Australia. Not every model in the catalogue suits a home. We’ve narrowed it to the residential-format panels, with the specs, warranty details, and WA-specific context you need to make a confident decision.

LONGi is the world's largest solar panel manufacturer by shipment volume and the only panel brand holding a AAA bankability rating from PV ModuleTech. Important because a 25-year warranty is only as good as the company standing behind it.
LONGi's HPBC cell technology moves all electrical contacts to the rear of the cell (no front busbars), which improves light capture and efficiency while running cooler. The -0.29%/°C temperature coefficient matters on 38°C+ Perth days when cell temperatures can exceed 60°C.
Coastal context matters: if your home is within 5km of the ocean, the Guardian's dual-glass and anti-corrosion design gives real protection over a 25-year service life. Within 50m of the beach, additional anti-corrosion treatment is required regardless of panel choice.

LONGi shipped over 63GW of solar cells and modules in the first nine months of 2025 alone. They’ve held the top manufacturing position globally since 2020, and they’re one of only few panel brands to hold a AAA bankability rating from PV ModuleTech.

Bankability matters because it signals financial stability. A 25-year warranty is only as good as the company standing behind it. LONGi’s vertically integrated manufacturing (they make everything from raw silicon ingots to finished modules) gives them cost control that most competitors can’t match, and that control shows up in the price you pay without sacrificing cell quality.

For Perth homeowners, three things stand out. LONGi only uses monocrystalline silicon, which is more efficient than the polysilicon some budget brands still use. Their HPBC cell technology (more on that below) is purpose-built for rooftop applications. And they maintain an Australian office with a local warranty claims process, which matters more than you’d think until you need it.

HPBC stands for Hybrid Passivated Back Contact. It’s LONGi’s alternative to N-type TOPCon cells, which dominate the rest of the market. The difference you can see: no busbars on the panel’s front. The difference you can’t see: the entire electrical contact structure is moved to the rear of the cell.

That front-side busbar-free design does two things. It captures more light (no metal strips blocking the cell surface), and it produces a cleaner, more uniform appearance on your roof. LONGi’s HPBC cells exceed 25% cell efficiency in mass production, with the upgraded HPBC+ cells pushing past 25.8%.

Perth-specific benefit: HPBC cells handle temperature better than older P-type PERC panels. With a temperature coefficient around -0.29%/°C, output drops by roughly 5.8% when cell temperature climbs from 25°C to 45°C. On a 38°C Perth summer day, panel cell temperatures can easily exceed 60°C, so every fraction of a percent in temperature coefficient performance counts toward real energy yield.

LONGi recently rebranded its distributed generation (rooftop) modules under the Hi-MO X6 banner. If you’ve been researching and see references to “Hi-MO 6,” it’s the same platform with incremental cell upgrades. The X6 is the current generation.

Three sub-models matter for Perth homes. All use HPBC cells in the M10 (182mm) wafer format, and all come in the residential-standard 54-cell configuration (108 half-cells) that fits standard Australian rooftops without the weight and size penalties of commercial-format 72-cell panels.

*Product warranty varies by specific model code. Always confirm the warranty tier on the datasheet for the exact panel quoted to you. Perth Solar Warehouse will confirm this during the quoting process.

Explorer

The volume residential pick

The Explorer is LONGi’s highest-volume residential panel globally, and it’s the one most Perth homeowners will end up with. Available in both standard white-backsheet (HTH) and all-black (HTB) variants, it hits the sweet spot between HPBC performance and sharp pricing.

At 440W in the HTH variant, you need 15 panels for a 6.6kW system. That’s roughly 27 square metres of roof space. The all-black HTB variant tops out at 435W, so you’d need the same 15 panels but with a slightly cleaner aesthetic on street-facing roof planes.

If your decision comes down to budget and you’re not in a coastal or high-humidity location, the Explorer is the right starting point.

Scientist

When maximum efficiency matters

The Scientist uses LONGi’s upgraded HPBC Pro cells with efficiency exceeding 25.3% at the cell level and up to 23.2% at the module level. That’s among the highest for any panel in this form factor available in Australia.

Where this matters most: constrained roof space. If your usable area is limited by hips, valleys, ventilation, or shading, every watt per square metre counts. The Scientist pulls more energy from the same footprint. It also carries a 25-year product warranty as standard, which removes the need to verify warranty tier against the datasheet.

Guardian

Built for coastal and harsh environments

Perth’s metro area stretches along 100+ kilometres of coastline. If your home is within a few kilometres of the ocean, salt mist, humidity, and UV intensity all accelerate panel degradation over a 25-year service life.

The Guardian addresses this with dual-glass construction (glass-glass instead of glass-backsheet), enhanced moisture sealing, and an anti-dust frame design. It carries a 30-year performance warranty, which is five years longer than the Explorer’s standard coverage. LONGi’s installation guidelines recommend anti-corrosion treatment for any panel installed within 50 metres of the beach, but the Guardian’s construction gives it a meaningful advantage in the 500m to 5km coastal band where many Perth homes sit.

LONGi makes 72-cell panels in the Hi-MO X6 range with power outputs exceeding 580W. They’re physically larger, heavier, and designed for commercial rooftops and ground-mount systems. Some installers will quote them for homes because the per-watt cost looks attractive.

We don’t. Here’s why.

Australian residential rooftops aren’t flat commercial expanses. They have hips, valleys, chimneys, whirlybirds, and satellite dishes. A 72-cell panel at roughly 2278 × 1134mm and 27kg can’t squeeze into gaps that a 54-cell panel at 1722 × 1134mm and 21kg fills comfortably. The larger panels also concentrate more weight per mounting point, which matters on older timber-framed roofs common across Perth’s established suburbs.

Fifteen residential-format 440W panels give you 6.6kW. The same capacity in 72-cell panels requires fewer panels but covers a larger total area once you account for the gaps created by panels that can’t work around roof obstacles. In practice, the 54-cell format almost always yields a better-optimised array layout on a real residential roof.

RESIDENTIAL: LONGi’s warranty structure in Australia has improved significantly since 2023, when they extended the Hi-MO 5m product warranty from 15 to 25 years for the Australian and New Zealand market. The Hi-MO X6 range continues this trajectory, though warranty terms vary by model.

Product warranty

Materials and workmanship

This covers manufacturing defects, materials, and processing faults. Depending on the specific Hi-MO X6 model, you’ll receive either 15 or 25 years. The Scientist and Guardian carry 25 years as standard. Some Explorer models carry 15 years. Always confirm the product warranty on the quoted panel’s datasheet before signing off.

Performance warranty

Power output degradation

All Hi-MO X6 panels in Australia carry a 25-year performance warranty guaranteeing no more than 1.5% degradation in year one and no more than 0.4% per year thereafter. By year 25, your panels are warranted to produce at least 88.9% of their original rated output. The Guardian’s dual-glass models extend this to 30 years at 86.9%.

These degradation rates are competitive but not exceptional by 2026 standards. What makes LONGi’s warranty more practical than some competitors is the local enforcement mechanism: LONGi maintains an Australian office (02 8484 5805) and a documented claims process. Your first point of contact for any warranty issue is your installer, but if the installer is no longer operating, you have a direct path to the manufacturer.

LONGi competes at the quality-value intersection. They’re not the cheapest panels available in Perth, and they’re not the most expensive. Their strength is delivering HPBC cell technology (a genuine performance advantage over older PERC panels) at a price point that undercuts most N-type TOPCon competitors.

The trade-off is cell architecture philosophy. Most of the industry has moved to N-type TOPCon as the baseline quality standard. LONGi has bet on HPBC (which uses P-type wafers) as an alternative path to high efficiency. Both approaches achieve similar real-world results in Perth’s climate. LONGi’s HPBC panels match or exceed the temperature coefficient, efficiency, and degradation rates of mainstream TOPCon panels. The debate between the two technologies is more relevant to manufacturers than to homeowners.

What should matter to you: the panel’s efficiency, its warranty terms, its temperature performance in WA conditions, and whether the manufacturer will still be around in 15 years. LONGi ticks every box.

LONGi panels are eligible for Small-scale Technology Certificates (STCs) in Zone 3, which covers Perth and most of the SWIS grid area. STCs are not a government rebate. They’re tradeable certificates created when you install an eligible solar system, and their value is deducted from your system price at the point of sale. Perth Solar Warehouse handles the STC paperwork and applies the discount directly to your quoted price.

Your LONGi panels will generate more electricity than you use during the day. Excess energy exports to the grid under Synergy’s Distributed Energy Buyback Scheme (DEBS), which pays variable rates depending on the time of export. Peak rates apply in the early morning and evening; midday rates are minimal. This is why pairing panels with a battery increasingly makes sense for Perth homes, but the panel choice itself doesn’t affect your DEBS eligibility or rates.

LONGi recommends a minimum 10° tilt to allow rain to clean the panel surface effectively. Most Perth rooftops naturally exceed this. North-facing arrays at 20–25° tilt produce the highest annual yield in Perth’s latitude, but west-facing arrays are increasingly popular to capture afternoon generation that aligns with evening consumption.

Is LONGi a Tier-1 solar panel manufacturer?

Yes. LONGi consistently appears on Bloomberg NEF’s Tier 1 module maker list and holds the only AAA bankability rating from PV ModuleTech. Tier 1 status reflects manufacturing scale and financial stability, not a quality grade, but LONGi’s independent testing results and bankability rating provide the quality signal Tier 1 doesn’t.

Where are LONGi solar panels manufactured?

LONGi operates manufacturing facilities across China (eight provinces), Malaysia (Kuching), and Vietnam. Panels sold in Australia are most commonly manufactured in China or Malaysia. The manufacturing origin doesn’t affect warranty coverage in Australia.

Is HPBC better than TOPCon?

They’re different approaches to the same goal: higher efficiency and better real-world performance. HPBC uses P-type silicon with back contacts and achieves efficiencies similar to or better than those of most TOPCon panels at a lower manufacturing cost. For homeowners, the practical performance in Perth’s climate is comparable. Choose based on warranty terms, pricing, and your installer’s recommendation rather than cell technology alone.

The best LONGi panel for your home depends on your roof layout, your proximity to the coast, and your budget. Perth Solar Warehouse installs LONGi Hi-MO X6 panels across the Perth metro area from two locations: Bibra Lake in the south and Neerabup in the north.
