5 Questions to Ask Before Signing a Solar Loan
A solar loan can make going solar affordable without draining your savings. But not every loan is worth signing. Some come with fees buried in the fine print, interest rates that wipe out your bill savings, or terms that cause problems when you sell your home. Before you put your name on anything, get clear answers to these five questions.
What Is the Interest Rate and Is It Fixed or Variable?
This is the first number to nail down. A low advertised rate sometimes turns into a variable rate that climbs after the first year. Ask the lender directly: is this rate fixed for the full loan term, or can it change?
On a $15,000 solar loan, even a 2% rate difference adds thousands of dollars over seven years. Get the rate in writing before you agree to anything else.
Also ask for the comparison rate, not just the headline rate. The comparison rate rolls in fees and gives you a truer picture of what you'll actually pay.
Are There Any Fees Beyond the Interest?
Origination fees, monthly account fees, early repayment penalties. These can quietly eat into the money you save on power bills.
Ask for a full list of fees in writing. Common ones to watch for include:
- Application or establishment fees charged upfront
- Monthly or annual account-keeping fees
- Early repayment fees if you want to pay the loan off faster
- Late payment penalties and how quickly they apply
Some solar financing products marketed to Brisbane homeowners look attractive on the surface but carry $300 or more in annual fees. That adds up fast over a five or seven-year term.
Does the Loan Attach to My Home or Just to Me?
Some solar loans are secured against your property. Others are personal loans tied to you as an individual. The difference matters more than most people realise.
A property-secured loan can complicate a home sale. The buyer may need to pay it out at settlement, or the loan might transfer to them. Either way, it can slow down or derail a sale if you don't flag it early.
A personal unsecured loan is simpler in that regard, but it often carries a higher interest rate. Know which type you're signing before you commit.
If you're unsure how your loan type interacts with your property, talk to your conveyancer or a financial adviser before signing.
What Happens If the System Underperforms?
A solar loan doesn't care whether your panels produce the power they were promised to produce. You make repayments whether your system performs well or barely at all.
This is why a proper solar assessment before installation matters. You want to know what the system is actually expected to generate based on your roof's angle, shading, and local weather patterns. An accurate estimate lets you judge whether the bill savings will genuinely cover the repayments.
Ask your installer what the production estimate is based on and get it in writing. Then ask what recourse you have if the system consistently falls short. A good solar warranty from the installer or manufacturer should cover equipment faults, but it won't cover a poorly designed system that was never going to hit those numbers.
Pairing your loan decision with a solid solar system design review is one of the smartest things you can do before signing.
Can I Pay It Off Early Without Penalty?
Feed-in tariff credits, lower power bills, a bonus at work. Sometimes you find yourself in a position to pay the loan off ahead of schedule. Some lenders charge a break fee or early repayment fee that makes that almost pointless.
Ask specifically: "Is there any cost to paying this loan off early?" If the answer is yes, ask for the exact figure or formula. A loan with no early repayment penalty gives you flexibility. That flexibility is worth paying a little more for upfront if you think there's a chance you'll want to clear the debt quickly.
Setting up feed-in tariff income through a proper feed-in tariff setup can sometimes generate enough ongoing credit to accelerate repayments over time. Factor that into your thinking when you compare loan terms.
Who Arranged This Loan and Do They Have a Credit Licence?
Some solar installers offer finance directly or push you toward a specific lender. That's not automatically a problem, but you should know who you're dealing with.
In Australia, anyone who provides credit assistance needs to hold an Australian Credit Licence or be an authorised representative of a licence holder. Ask to see it. You can also check ASIC's register online at no cost.
Be cautious if you're being rushed. A legitimate lender gives you time to read the contract and ask questions. Pressure to sign on the day of your quote is a red flag, not a sales tactic you should accept.
Getting solar right means getting the finance right first. Read the loan contract carefully, ask every question on this list, and don't sign until you have clear written answers.
