Loan products / Green loans
Finance the upgrade. Let the sun pay it off.
Solar, batteries, heat pumps, and home energy upgrades at discounted green rates. NIK Finance compares 130+ lenders, and for many households the energy savings outrun the repayments.
What Is a Green Loan?
A green loan is a personal loan with a discounted rate, reserved for energy-efficient purchases: solar panels, home batteries, heat pumps, EV chargers, insulation, and double glazing. Because the upgrade cuts your household running costs, lenders price these loans 1-3% below their standard personal loan rates.
You can borrow $2,000 to $80,000 over 1 to 7 years, with fixed repayments that make budgeting simple. Government incentives like Small-scale Technology Certificates (STCs) typically reduce a solar quote by $2,000-5,000 before you borrow, so you finance less than the sticker price.
The unusual thing about green finance is the cashflow math: for many households, the monthly energy saving is bigger than the monthly repayment. NIK Finance brokers compare 130+ lenders, check whether a green loan or a mortgage top-up costs you less, and structure the term so the upgrade pays for itself as fast as possible. The service is free.
What Can a Green Loan Finance?
Any upgrade that cuts your energy use can qualify, and most can be bundled into one loan
Solar Panel Systems
Finance a 6-13kW rooftop solar system and cut your electricity bill by 60-80%. STC rebates reduce the upfront cost before you borrow a cent.
Example: An $12,000 solar system financed over 5 years can save $200+/month on power, often more than the repayment itself.
Battery Storage
Add a home battery (Tesla Powerwall, BYD, Sungrow) to store solar power for the evening peak, or join a Virtual Power Plant for extra credits.
Example: Pair a $10,000 battery with existing solar and push your grid bill towards zero, with blackout protection included.
Heat Pumps & Hot Water
Replace gas or electric-resistive hot water with a heat pump system that uses up to 75% less energy, plus reverse-cycle heating and cooling.
Example: A $4,500 heat pump hot water system can save a family of four $600-900/year on energy.
EV Chargers
Install a home EV charger and charge overnight on off-peak rates, or free during the day from your own solar.
Example: A $2,500 wall charger plus solar can cut your driving costs to a fraction of petrol.
Insulation & Glazing
Double glazing, ceiling insulation, and draught sealing cut heating and cooling costs year-round and make your home more comfortable.
Example: A $15,000 insulation and glazing package can cut heating and cooling energy use by 40%+.
Full Home Electrification
Go all-electric in one project: solar, battery, heat pump, induction cooking, and EV charging, financed as a single package.
Example: A $35,000 whole-home package can eliminate gas bills entirely and slash your electricity costs.

Green Loan vs Personal Loan vs Mortgage Top-Up
Three ways to fund the same upgrade. The right one depends on your equity, timeline, and loan size.
| Feature | Green Loan | Personal Loan | Mortgage Top-Up |
|---|---|---|---|
| Interest Rate | Discounted (6.99% - 14% p.a.) | Standard (7% - 19.99% p.a.) | Lowest (5.5% - 7% p.a.) |
| Loan Amount | $2,000 - $80,000 | $2,000 - $50,000 | Limited by your equity |
| Approval Speed | 24-48 hours | 24-48 hours | 2-4 weeks (refinance/top-up) |
| Term | 1-7 years | 1-7 years | Up to 30 years |
| Best For | Eligible energy upgrades at a rate discount | Upgrades that don't meet green criteria | Large projects when you have equity and time |
A mortgage top-up has the lowest rate but stretches the debt over decades. A NIK Finance broker will show you the total cost of each path for your project.

Green Loan FAQs
Common questions about financing solar, batteries, and energy upgrades in Australia
Frequently Asked Questions
A green loan is a personal loan with a discounted interest rate, offered specifically for energy-efficient purchases: solar panels, home batteries, heat pumps, EV chargers, insulation, double glazing, and similar upgrades. Lenders offer lower rates because green borrowers tend to be reliable and the upgrades reduce household running costs. In Australia, green loan rates currently start around 6.99% p.a., typically 1-3% below the same lender's standard personal loan rate.
For many Australian households, yes. If your monthly energy savings exceed your loan repayment, you are ahead from the first month. For example, a well-sized solar system might cut a $300/month power bill to $60/month, saving $240/month. On an $18,000 loan over 7 years, that saving can cover most or all of the repayment, and once the loan ends the savings are pure gain. Use our free Green Upgrade Calculator to model your exact scenario before you commit.
The federal Small-scale Renewable Energy Scheme (SRES) provides Small-scale Technology Certificates (STCs) that typically knock $2,000-5,000 off the cost of a solar installation. States add their own programs, such as the Victorian Solar Homes Program and the Queensland Battery Booster. Rebates are usually applied by the installer at the point of quote, which means you borrow less and your repayments are lower. Always get quotes with rebates already factored in.
For fixed installations like solar panels and heat pumps, most lenders require you to own the property (or have the owner's consent for strata). Renters can still finance portable upgrades. If you have a mortgage, you may also have the option of a home loan top-up at an even lower rate. NIK Finance brokers compare both paths and show you which one costs less over the life of the upgrade.
Yes. Green loans are credit-scored like personal loans, so a stronger credit profile gets a lower rate, but there are lenders across the spectrum. If your credit history has bumps, we can match you with lenders who focus on your current income and repayment capacity. Expect a higher rate, and consider a smaller starter upgrade (like hot water) that improves both your energy bill and your credit profile before a bigger project.
