Every budget panel on the market carries a 25-year performance warranty. That number is printed on the datasheet, it goes on the quote, and the customer nods along like it means something. The question I learned to ask a long time ago, after watching the same movie play out more than once, is simpler and harder: who is actually going to be standing behind that piece of paper in year 10?
That is not a consumer question. It is a business risk question, and it is yours, not the customer’s.
The warranty maths nobody runs
A 25-year product warranty from a company that has been trading in Australia for four years is a fundamentally different promise to the same warranty from a company that has been here for twenty. The document reads identically. The risk does not.
The customer cannot see this distinction, and frankly it is not their job to. They are comparing two quotes with the same headline warranty and a price gap. You are the one who knows that a warranty is a forward promise, and a promise is only as good as the entity making it. When that entity is a brand with no manufacturing history you can verify, the warranty is closer to a marketing line than a financial backstop.
I have watched panels go from 165W to over 600W, and I have watched the brand landscape churn the whole way through. Brands arrive with aggressive pricing, build volume fast, and some of them quietly fold or exit the market a few years later. When that happens, the warranty does not transfer to anyone. It just evaporates.
The disappeared-brand pattern, and why it lands on you
Here is the part that matters for your business. When a manufacturer disappears, the customer does not ring a head office in another country. They ring you. You sold it, you installed it, you are the face they remember.
Under the Australian Consumer Law, consumer guarantees apply to goods sold to consumers regardless of any separate manufacturer warranty, and the supplier in the transaction can carry liability for a product that fails to meet acceptable quality (Australian Competition and Consumer Commission, 2023). In plain terms: even when the overseas manufacturer is gone, the customer still has rights, and you are the closest party still standing. The manufacturer’s warranty was supposed to be the thing that reimbursed you for honouring that. No manufacturer, no reimbursement.
So the truck roll is yours. The labour is yours. The replacement panel, sourced from somewhere else because the original brand no longer exists, is yours. The paperwork and the awkward phone call are yours. That fifty-dollar-per-panel saving you booked at quote time disappears in a single callback, and then some.
Signs a brand may not last
I cannot name specific failed brands here, and I would not without a verified, attributable source in front of me. What I can do is give you the pattern, because the pattern repeats regardless of the badge on the panel.
Watch for a new entrant leading almost entirely on price with little verifiable Australian market history. A rock-bottom quote on its own is not a concern. But when low pricing comes packaged with no installation history and no local presence, you have three warning signs landing at once.
Watch for no Australian-based technical support. A distributor helpline that reads from a script is not the same as a manufacturer with local technical staff who can actually authorise and process a claim.
Watch for a warranty serviced by an entity that is not the manufacturer. Third-party warranty insurance can sound reassuring, but it introduces another company who has to still be solvent, still be holding the policy, and still be willing to pay when you lodge in year 8.
Watch for a distributor who gets vague when you ask about the manufacturer’s history, ownership, or how long the factory has been producing. Reluctance to talk about the people behind the brand tells you something.
And watch for the contract-manufacturing tell: a brand label applied to a panel built in a factory the brand does not own and will not name. There is nothing illegal about it, but it means the “brand” is a marketing layer that can be packed up and walked away from quickly.
What staying power actually looks like
The flip side is easier to assess once you know what you are looking for.
A meaningful Australian market presence, ideally in the order of five to seven years or more, so you can see how they behaved across at least one downturn. Local technical support staff, not just a distributor passing messages along. A clear ownership structure and a registered Australian entity you can verify. You can check an ABN and the registered business details through the Australian Business Register and ASIC’s company search before you ever place an order (Australian Securities and Investments Commission, 2024). That is ten minutes of due diligence that costs nothing.
Warranty backed by the manufacturer directly, not bounced to a third party. And a track record of actually honouring claims that you can confirm through your own peer network rather than taking on faith.
The Clean Energy Council maintains an approved products list and a Solar Retailer Code of Conduct, and while approval is about the product and the retailer rather than a guarantee the company will survive, checking that the products you stock are on the current approved list is basic hygiene (Clean Energy Council, 2024). The ACCC has also published guidance over the years warning consumers and the trade about underbacked solar warranties and operators who do not stand behind their products (Australian Competition and Consumer Commission, 2023). If the regulators are flagging the risk, it is real.
The peer-network check is your fastest tool
Before I stock a brand I have not used, I want to talk to three other installers who have run it for two years or more. Not two months. Two years, because that is roughly when the first real warranty claims start landing and you find out what the process is actually like.
I ask them one direct question: when you lodged a claim, what happened? Did the manufacturer respond, did they pay, how long did it take, and did they cover your labour or just ship a panel? Three honest answers from operators who have lived it will tell you more than any glossy distributor deck ever will.
This is the single fastest piece of due diligence available to you, and it costs you nothing but a few phone calls. The industry is smaller than it looks. Most of us are one or two contacts away from someone who has used whatever you are considering. Use that.
If you are already wary of leaning your whole business on a single supplier, the same instinct applies to brands, and I have written more on that in why you should not rely on one solar supplier.
Your reputation is the long fuse
Here is the thing that makes equipment selection a business decision rather than a purchasing one. A poor brand choice you make this month does not blow up this month. It blows up in year 8, when a panel fails, the brand is gone, and a customer who has not thought about you in seven years suddenly remembers your name and your number.
The customer does not remember the brand. They remember who sold it to them. Your reputation is the long fuse on this, and the cheap-equipment decision is the spark. Most of the time nothing happens. But across enough installs and enough years, the probability stops being theoretical, and one bad run of a folded brand can do more damage to your referral pipeline than a season of slow leads.
So when you run the margin on a budget product, build the real cost in. Take the price saving, then subtract the probability of a warranty claim multiplied by the cost of servicing it with no manufacturer behind you. That is the honest number. Often it is still fine. Sometimes the cheap option is quietly the most expensive thing on your shelf.
This is also one of those decisions that is far easier to make well when your supplier and brand history is actually recorded somewhere you can search, instead of living in your head and a pile of old invoices. Knowing which brands you have on roofs, how many, and from which supplier turns a panicked year-8 phone call into a two-minute lookup. That record-keeping discipline is a big part of why I am building CurrentFlow, the tool I wished I had when I was carrying these relationships myself. The idea is to keep the brand, supplier and job history in one place so the long-fuse risk is visible long before it goes off.
You do not need software to start, though. You need to ask the longevity question out loud before you commit to a brand, run the ten-minute entity check, and make three phone calls to people who have used it. Do that consistently and you will dodge most of the brands that were never going to be there when the claim came in.

FAQ
Is a 25-year solar panel warranty actually guaranteed for 25 years?
No. The warranty is a promise from the manufacturer, and it is only enforceable if that manufacturer still exists and is still honouring claims when you lodge one. A 25-year document from a brand with only a few years of Australian trading history carries materially more risk than the same document from a long-established manufacturer. Always assess who is standing behind the paper, not just the number on it.
Who pays for a warranty claim if the solar brand has left the market?
In practice, you often do. When the manufacturer is gone there is no one to reimburse your truck roll, labour, and replacement product. Under Australian Consumer Law the customer still holds consumer guarantee rights against the supplier, which is frequently the installer or retailer (Australian Competition and Consumer Commission, 2023). That is why a folded brand becomes your problem, not the manufacturer’s.
How can I check whether a solar brand is financially legitimate in Australia?
Start by verifying the Australian entity. You can check an ABN through the Australian Business Register and search company and director details through ASIC (Australian Securities and Investments Commission, 2024). Confirm the products are on the Clean Energy Council’s current approved list (Clean Energy Council, 2024). Then make three calls to installers who have used the brand for two years or more and ask what their warranty claim experience was.
Are STCs a rebate that covers warranty risk?
No, and the two are unrelated. Small-scale Technology Certificates (STCs) are tradeable certificates created from a system’s deemed generation, which liable entities must surrender to the Clean Energy Regulator under the Renewable Energy Target (Clean Energy Regulator, 2024). They reduce the upfront cost of a system. They do nothing to protect you against a brand disappearing and leaving the warranty unhonoured. That risk sits entirely with your brand selection.
Does cheap equipment really cost more over time?
It can. The honest margin on a budget product is the price saving minus the probability of a warranty claim multiplied by the cost of servicing it with no manufacturer behind you. Across enough installs and enough years, a folded budget brand can cost you far more in callbacks and lost referrals than the upfront saving ever delivered. Sometimes the cheap panel is fine. Sometimes it is the most expensive thing on your shelf.
