FAQs about loans for solar power

Can I get an interest-free loan for solar panels?

It’s worth checking with your relevant government authorities to see if they're offering interest-free loans for solar systems. Many interest-free offers for solar power have now closed, but it's still worth researching to find the best finance option for you. Because the solar industry continues to evolve, it's worth ensuring any sources of information you use are up-to-date.

What credit score do you need for solar?

Our Unsecured Personal Loan for solar has the same lending criteria as borrowing for something else. Our Before you apply section gives a more comprehensive outline of requirements.

Can I add solar panels to my home loan?

Some people choose to add the cost of their solar to their home loan. The benefit being they don't need to apply for another loan. However, unless you are disciplined, and repay that additional amount off in a shorter period than the rest of your home loan, you could end up paying more in interest. That's why many people choose to take out a separate loan (such as this one) for their solar system, and keep things separate. Ultimately you’ll need to do the numbers and be realistic about additional repayments. 

Are solar loans tax deductible?

Many installers will be aware if any tax deductions are available for installing a solar panel system – with or without a battery – and will build it into their quote. Having said that, it's definitely worth checking for yourself with the ATO as their information will be the most up-to-date.

What's a green loan?

Green loans are personal loans that focus on lending for energy saving, electricity production or other environmentally-friendly products that help reduce our need for fossil fuels. They are still personal loans offered by financial institutions. Our Unsecured Personal Loan is a general-purpose loan with the flexibility to use the funds for green products, something else, or a combination as suits you. Like any loan, it's worth checking all the details - including interest rates and repayment terms - to see what works best for you.

Can I borrow for the solar panels now, and the battery later?

Most people researching a solar panel system will at some point decide whether they should get a battery up-front, or later on. There's no one answer to this as it'll depend on what you want from the solar system you're planning. Getting a battery at the same time as your solar panels makes it possible to 'go green' sooner, relying less on the grid and fluctuating energy prices.

However, the upfront cost of a battery will mean a bigger loan (if you're borrowing) and a longer payback period. On the other hand, battery technology is constantly improving, and some electric vehicles (EVs) can be used as a night-time battery for the house. So there are good arguments either way. In the end, if you choose to get a battery later by buying it outright, getting a separate loan for the battery, or by refinancing the loan you have for the solar panels (saving you on the loan establishment fee) when the time comes.

The details

Our Unsecured Personal Loan comes with a fixed rate, meaning that you have the certainty of a set repayment amount throughout the life of the loan. You can also make extra repayments to pay off your loan faster, giving you the best of both worlds (prepayment fee may apply#).
