Is Interest Free Solar too good to be true?

Certegy interest free solar loansWhy wouldn’t everyone be jumping at the chance? Get the solar power loan you need for installing solar and pay it off without the added cost of interest.  Well, it turns out that interest free solar loans are often too good to be true. In this blog, we will debunk the myths about interest free solar loans from the likes of Certegy and Brighte and explain why we choose to stay away from these types of loans. We’ll also discuss the reasons we use lenders like Green Loans and Classic Finance, and show how you could easily save over $1000 compared to a so-called “interest free solar” loan.

Interest Free lenders are everywhere!

Just when you think you’ve got on top of your expenses – BAM! – the fridge dies, or you need a new washing machine. Rather than using your credit card and paying some whopping interest rates, or taking out a personal loan, you decide to try out the interest free option you’ve been seeing all over the place.

You’ve probably heard of Certegy, who offer easily-approved finance for everything from jewellery, to electronics, to exercise equipment. Being able to walk into your store of choice, hand over a few details and walk out with a new purchase seems like a dream come true for a lot of consumers. But what’s the catch? How are these companies really making their money, if they’re not charging you any interest?

The reality with interest free lenders is that they make their money from fees and charges payable by you, the customer, as well as by charging the retailer a percentage of the sale which (surprise, surprise) are just added to the cost of the product. This is roughly how it works with purchasing Solar with Certegy.

Interest Free Solar charges to the Solar Sales company

Ok, fair enough. If I want to offer the services of Certegy “interest free solar” loans in my business, I would expect to pay for that service. How much?  It’s confusing, and it depends on the loan amount, the term of the loan, and the amount of the deposit. But as a rule of thumb, it is about …. 23 freaking percent of their sell price for the solar system! So a system that would have been sold for $7000 would have $1610 of charges to the company that sells it. Deceitfully, Certegy insists that the retailer cannot add the charges on to the cost of the system. But don’t be fooled. Any solar company that has to pay that does not just “absorb it”.   It gets factored into the cost of your system. So you would pay the retailer the inflated price of $8610 for a $7000 system.

That’s why they use the euphemism “a discount for cash”.

Interest free solar price:             $8610
Cash price:                             $7000

As the Good Guys sing so joyfully: ‘pay cash, and we’ll slash the prices.”

The reality: you are getting slugged 23 percent for “no interest ever”.

But wait, there’s more..

“Interest free Solar” charges directly to the customer

On top of the charges the Solar retailer passes on to the customer, the end customer also pays:

  • $3.50 monthly Revolving Credit Account fees (even after you have paid off the loan – until you close the account)
  • $2.95 Fortnightly Payment processing fees
  • $35 to $90 customer establishment fee (depending on the deal the retailer gets)
  • $15 Late payment fees
  • $15 Change of details fees (for changing any of the details around your arrangement, such as payment dates etc.)
  • $30 Collection fees (on top of a late payment fee!)
  • $22 Repeat purchase fees. (Consider it a customer loyalty fee).
  • Up to 40 months

Over three years, you have a minimum of $446 of fees to add on top the $1610 that the sales company will add on to your system.

A loan through Certegy of $7000 over 3 years will cost a total of $9056. 
Plus late fees, change of details, collection fees, repeat purchase fees, and revolving credit account fees because you forgot to cancel it.
(But don’t worry, there is no interest ever!)

How do they get away with it?

National Consumer Credit Protection Act

Australia has legislation in place to protect consumers who borrow money. It’s called the  “National Consumer Credit Protection Act.” However, because of the interest-free loophole, Certegy and Bright are not regulated by the NCCP Act. The Clean Energy Council explains that as a result:

  1. If you have a complaint about your agreement, you may not have access to the services of an external dispute resolution scheme that has been approved by ASIC. You may have to go to court to resolve a dispute with the provider.
  2. If you have trouble making periodic payments, you may not have the right to ask the provider for a hardship variation to help you get through your financial difficulty.
  3. If you have trouble making payments, your provider may take action against you for non-payment without giving you a chance to remedy the fault.


Our chosen lenders

At MC Electrical, we choose ethical lenders only. Making sure that solar customers can not only get the system that’s right for them, but get it at the best price, and with a finance solution that’s leaving them better (and not worse) off should be a number one priority for all solar retailers and installers. Furthermore, it’s crucial for ensuring the long-term viability of the industry. So, which lenders do we choose and why? Here, we’ll give you the experiences we’ve had with our chosen lenders and help you to understand why they’re our top picks.

Community First – Green Loans

Community First Green Loans

“Green Loans” is a loan offered by Community First Credit Union designed for financing residential solar systems. It will often be our first port of call for financing our client’s solar systems, and this comes down to a few key factors.

  • Interest rate 5.54% – 6.52% depending on fixed/variable or comparison rate
  • Making weekly, fortnightly or monthly repayments
  • Redraw payments in advance
  • Pay your loan out early (fees apply for early payout of fixed loans)
  • Fixed or variable loan terms between 1 and 10 years
  • Unsecured loan
  • $195 one-off application fee
  • $10 monthly fees
  • You can also include the cost of an EV charging station in your loan.

Community First explains that the reason they can make their Green Loan so competitive is because it’s great marketing for them. They’ll get your foot in their door, with the hope that further down the track, you’ll get a credit card or car loan off them. You might even end up doing all your banking with them.


Interest-free Solar Loans are not all they are cracked up to be. We’ve compared two loans and used the example of a $7000 solar system paid off over three years. In this example, Certegy is $1196 more expensive than a Green Loan through Community First Credit Union. So Certegy’s “interest-free” loan was more expensive than lenders that are honest and upfront about their charges. You should note that if you use Certegy, you are not protected under the National Consumer Protection Act. That’s why I cringe whenever I hear “interest-free solar”.

This blog should not be considered financial advice. I’m just a sparkie. Contact the lenders for accurate and up-to-date figures.

That sounds pretty expensive with 23%. But are you sure that is the number? I've heard it is much less by now, more like 10%. Could you give me some insights on that =)?

Hey Andrew, yes, and interest free loans usually works out to be more expensive. And, you have none of the protections granted to the more affordable interest loans under the law.

Andrew said : Guest Report 5 years ago

Another point to note is that there is no advantage in paying out the "interest free" loans early. The "interest" has already been paid to the supplier/retailer upfront in the form of a "fee". All financial products have their pros and cons and " interest free" has its place. The point being made if I understand it correctly is interest free is simply not interest free.

Hi Darren, To me, your article seems more like a promotion for Bright, because you didn't state what the charges to the retailer are. These charges are obviously passed on to the customer and work out to be more expensive than an honest and upfront low-interest loan that is regulated by the "National Consumer Credit Protection Act". The point of my blog is to say that the term "interest-free" is deliberately deceptive, more expensive, and these loans are not covered by the NCCPA. I've got no time for deceptive people. But maybe I'm wrong. Why don't you publish those numbers, and rebut the point about the NCCPA?

Great article Mark and I can see how debunking the interest free solar products gives consumers a better understanding of the fee's accociated with interest free retail finance. In my opinion, there is a place in the market for products like Certegy's Ezy-Pay and Brighte's no interest payment plan. I've reviewed the Brighte Capital no interest plan and although not directly comparing to the other loans on the market as you have done in this article, I've pointed out some of the benefits. You can read about it here.

Thanks Nigel, yeh it's a blog I should have done a long time ago. We often have to explain to customers that interest-free is not cost-free.

finn peacock said : Guest Report 6 years ago

Brilliant Mark. I've been advising people for years to avoid 'No Interest Deals' and just get a low rate loan. Great to see some real numbers from a real solar company! Keep up the good work. Finn

Wow - sensational work Mark. I think it's high time that these mythical, unicorn like offers are debunked for what they really are. Solar consumers take note - there's no such thing as a free lunch.

Last year I contacted my electricity retailer about their cost for installing a solar system. The consultant was all excited about offering me a new "interest free" product that I could pay with my electricity savings and quoted my a bit over $11,000 for my desired system. It was difficult for him to understand that I wanted to pay cash for my installation and expected a reduced price. He was adamant that their price was still $11,000 plus. After I insisted that he talk to his manager, he came back flabbergasted that his manager had priced my quote at $8500 for cash.
