“Buy Now, Pay Later” Solar Tricks And Traps

You can have solar installed on your home with a Buy Now, Pay Later (BNPL) “0% interest payment plan” and pay nothing up-front – but should you?
Australia’s long-running solar rebate, and the home battery rebate starting in July 2025 are actually point-of-sale discounts and are really generous. However, it can remain challenging to find the cash needed to buy a power bill-busting solar system, energy storage or other home electrification products.
In recent years, “Buy Now, Pay Later” (BNPL) finance has sprung up everywhere and proved to be a pretty popular way of getting solar panels installed without having to find the cash upfront.
How Has BNPL Worked In Solar Sales?
It’s been pretty straightforward.
BNPL providers enter into arrangements with solar retailers, who then offer a “0% interest payment plan” in their marketing and during the sales process. When a customer expresses an interest, there’s been a pretty quick (and IMO, at times slack) pre-approval process by the BNPL provider that can take just minutes. Once pre-approved, you were good to go.
Aside from paying off the system over 6 months to 60 months depending on the arrangement, there’s usually only a monthly account keeping fee (e.g. $1.50 a week). And, of course, late fees if you should miss a payment – but these are often capped.
Sounds pretty good so far, right? But …
0% Interest? Really?
The marketing of BNPL products hinges on the so-called “0% interest payment plan” – and it really irks me. While it may be technically correct and legal, it clearly implies that the finance is almost zero-cost compared to a loan with a realistic interest rate.
There is no such thing as a free lunch, and that applies to any sort of financing.
The Truth About Most 0% Interest Schemes
Solar businesses offering “0% interest payment plan” options typically pay 15-25% of the system cost to the BNPL provider.
So if they were charging you $10,000 for a solar power system, they would have to pay $1,500 to $2,500 of that to the BNPL provider to give you that 0% interest deal.
For some solar installers, that could leave no profit margin.
So what do they do? They add the cost of finance to the price. Now the $10,000 system is $12,000.
But there’s a big problem.
The BNPL operator must be able to imply that their finance is at no-cost to the consumer for 2 reasons.
- Because their only marketing hook is that the finance is 0% – implying that the consumer is paying no penalty for not having the cash.
- If the cost of the BNPL finance is ‘a cost of doing business’ for the retailer – the BNPL operator has been able claim it is not a financial product and (until recently) avoided all that pesky financial regulation stuff.
So the BNPL operator has been prohibiting the retailer from advertising or quoting systems at a higher price with 0% finance.
The retailer can offer a discount for cash if you ask, but they can’t add a premium for 0% interest.
So what happens?
Either the retailer breaks the rules, or they put up their prices for everyone, or they have special product bundles that they only offer with 0% interest.
Can you see how the industry ties itself up in knots to imply that 0% finance is free or low-cost?
That’s why I hate it!
The bottom line is the cost of these “0% interest” payment plan deals is ultimately borne by those purchasing systems – and often not just on Buy Now, Pay Later sales.
BNPL Solar Raises Prices For All
So, as you have now learned, when solar businesses want to offer BNPL, among the *many* conditions imposed by the BNPL provider is the retailer cannot offer and advertise cheaper prices for cash-only.
The savvy cash customer will know to haggle on system pricing. But depending on how the business has spread the cost of their Buy Now, Pay Later obligations, there may not be much wriggle room for negotiation.
Dodging *Proper* Government Oversight
It’s these sorts of shady conditions and the general nature of Buy Now, Pay Later “0% interest” payment plans that previously enabled BNPL providers to avoid the same regulatory oversight as conventional credit providers.
Up until June 10, 2025, they haven’t been required to hold a credit licence, nor subject to observing consumer protections under the National Consumer Credit Protection Act 2009.
The other major issue – as repeatedly reported by major welfare and consumer groups – is buyers being approved for these payment plans who simply can’t afford them. And at times, dodgy solar companies have conned Australians into buying incredibly overpriced crap systems that don’t suit their circumstances under these plans.
In June 2022, Federal Financial Services Minister Stephen Jones said Buy Now, Pay Later providers should be regulated like other suppliers of credit services – and I totally agreed with him.
There was some talk a few years ago of this happening, but the BNPL sector saw the writing on the wall and banded together to come up with an industry-devised Code Of Conduct in an effort to keep proper oversight at bay. After some tweaking, this Code was approved by the Australian Competition and Consumer Commission (ACCC).
This was a case of the fox watching over the hen-house as the Code is severely lacking. For example, it only obliged BNPL providers to assess if a borrower can make the first payment; not subsequent payments.
BNPL Regulation Tightens Up In 2025
BNPL’s time away from increased scrutiny and oversight has thankfully come to an end. As of June 10, 2025, all BNPL providers must:
- Hold a credit licence (or have applied for one) and be members of the Australian Financial Complaints Authority.
- Check the customer can manage ongoing repayments — but they don’t have to verify this information.
- Clearly detail any fees, charges, or terms
- Offer customers doing it tough hardship support
While there are still some holes, these changes are for the better.
This means any quote you get for a BNPL financed system should contain:
- Information often you’ll be making payments
- How much each repayment will be.
- How many repayments there are over the course of the contract.
- The total you’ll end up paying for the system.
If any of these items are missing, then the quote in violation of regulatory requirements.
BNPL Has A New Sting In Its Tail
While consumer protections have been improved with these changes, because BNPL is now regulated like other credit products, more credit checks and reporting are involved. This means if you have too many BNPL arrangements on the go or start missing payments, it could affect your credit score negatively and lenders viewing you as high-risk.
Should You Avoid Installers Offering BNPL?
I found the whole “0% interest payment plan” approach of Buy Now, Pay Later as it stood unsettling, and it remains to be seen how it will evolve with the new requirements.
I’ve had BNPL providers approach me, wanting to offer their finance products via SolarQuotes. But given the nature of SolarQuotes – very different to that of installers – the terms and conditions were just horrid. And if it’s bad for SolarQuotes, then it’s bad for the many thousands of Australian solar buyers who trust my service and the information it provides.
While I have a low opinion of BNPL providers as they have been operating, that opinion doesn’t extend to (all) solar installers offering 0% interest payment plans. Many great solar businesses do. It’s a case of consumer demand – if these businesses don’t offer BNPL, they’ll lose sales.
A Caveat – Government-Funded No-Interest Finance
Some state governments—such as Victoria—offer genuine, taxpayer-subsidised, no-interest finance for part of the purchase price. For example, in VIC, the interest-free solar loan is only $1,400.
