Funding solar panels without draining your working capital
Equipment finance lets you install commercial solar panels by spreading the cost over monthly repayments instead of paying a lump sum upfront. The solar system itself acts as security for the loan, which means you can access the technology without tying up cash reserves that your business needs for day-to-day operations.
In our experience, businesses often delay going solar because they assume they need $40,000 to $80,000 sitting in the bank account ready to spend. Equipment finance changes that equation. You arrange funding through a lender, the system gets installed, and you begin repayments at the same time your energy bills start dropping.
The loan amount typically covers the full installation cost including panels, inverters, mounting hardware, and labour. Some lenders will also roll in monitoring systems and battery storage if they form part of the initial setup. Repayment terms usually run between two and seven years depending on the size of the system and your business structure.
How a chattel mortgage works for solar installations
A chattel mortgage is one of the most common structures for financing commercial solar equipment. You take ownership of the solar system from day one, and the lender holds a mortgage over it until the loan is repaid. This structure allows businesses to claim depreciation and GST input tax credits where applicable.
Consider a logistics business that operates from a large warehouse with high daytime electricity usage. They arrange a chattel mortgage to finance a 100kW solar array. The business owns the system immediately, claims the GST back in the next activity statement, and begins depreciating the asset. Monthly repayments are structured as a business expense, and the reduction in grid electricity costs offsets a portion of those repayments from month one.
The chattel mortgage also gives you a residual or balloon payment option at the end of the term. You can choose a residual value of up to 20% on a five-year loan, which reduces the monthly repayment amount but leaves a final lump sum due at the end. For solar systems, most businesses opt for a low or zero residual because the equipment has already delivered its value through energy savings by that point.
Tax treatment and deductions on solar equipment
Solar panels installed for business purposes are classed as plant and equipment, which makes them tax deductible under depreciation rules. Depending on the size of your business and the date of installation, you may be eligible for instant asset write-off provisions that allow you to deduct the full cost in the year of purchase.
Interest charged on the loan is also tax deductible as a business expense. If you structure the finance as a chattel mortgage, your business claims both the depreciation on the solar system and the interest component of each repayment. This makes solar equipment finance particularly tax effective compared to paying cash, where you only claim depreciation and lose the ability to deduct interest.
A regional manufacturer installing a 50kW system might finance $60,000 over five years. The monthly repayments are an operating cost, the interest portion is deductible, and the business writes off the asset value according to the applicable depreciation rate. The combination often means the after-tax cost of the solar installation is considerably lower than the sticker price.

Comparing a chattel mortgage to a hire purchase arrangement
Hire purchase is another structure used for equipment finance. Under this arrangement, the lender owns the solar system during the loan term, and ownership transfers to you once the final payment is made. You still get to use the system and benefit from the energy savings, but the legal title stays with the lender until the agreement concludes.
The main difference is timing of ownership. With a chattel mortgage, you own the system from day one and the lender holds security. With hire purchase, the lender owns it until you finish paying. For solar installations, this affects depreciation timing and your ability to claim GST upfront. Most businesses prefer chattel mortgages for solar because immediate ownership unlocks the tax benefits sooner.
Monthly repayments under hire purchase are usually structured similarly to a chattel mortgage. Both options result in full ownership at the end, and both allow you to install the system now rather than waiting until you have saved the full amount. Your accountant can guide you on which structure suits your business tax position.
How lenders assess solar equipment finance applications
Lenders look at your business financials, credit history, and how long you have been operating. For equipment finance, they also consider the type of equipment being purchased. Solar systems are viewed favourably because they generate measurable savings and the equipment itself acts as collateral.
You will typically need to provide recent business financial statements, tax returns, and a quote from the solar installer. Lenders want to see that your business generates enough income to cover the monthly repayments comfortably. Because solar reduces operating costs, some lenders will factor the expected energy savings into their serviceability assessment.
Approval timeframes are usually faster than commercial loans for property because the security is straightforward and the loan amount is smaller. In many cases, you can have finance approved within a few business days, which allows you to lock in an installation date without delays.
Structuring repayments to match your cashflow
One of the practical benefits of equipment finance for solar is that you can align the repayment term with the expected payback period from energy savings. If your solar installer estimates the system will reduce electricity costs by $1,500 per month, you can structure the loan so monthly repayments sit below or close to that figure.
This approach means the solar system funds itself over time. Your business still has a monthly commitment, but the net impact on cashflow is minimal because the savings offset the repayment. Once the loan term ends, the full value of the energy savings flows directly to your bottom line.
Some lenders offer seasonal repayment structures for businesses with variable income throughout the year, such as agricultural operations or tourism-related enterprises. You pay more during high-income months and less during quieter periods. This flexibility helps manage cashflow while still upgrading to solar technology without waiting.
Why businesses choose finance over paying cash for solar
Even when a business has the cash available, financing solar equipment often makes more financial sense. Paying $60,000 upfront removes that capital from your business permanently. Financing the same amount over five years keeps that $60,000 available for stock, wages, or unexpected costs.
Interest rates on equipment finance are typically higher than home loan rates but lower than unsecured business loans. The solar system acts as security, which reduces the lender's risk and improves your borrowing terms. You are also leveraging the tax deductibility of interest and depreciation, which lowers the effective cost of borrowing.
Another factor is technology upgrades. Solar technology improves steadily, but the systems installed today still have a productive life of 20 to 25 years. Financing over five to seven years means you own the system outright well before it reaches end of life, and you have preserved working capital for other business improvements during that period.
How to move forward with solar equipment finance
Start by getting a detailed quote from a solar installer that includes system size, expected output, and installation costs. That quote becomes the basis for your finance application. Once you know the loan amount, you can compare lenders and structures to find the option that suits your business needs.
We work with lenders across Australia who understand commercial solar installations and can structure finance around your circumstances. Whether you operate a small office or a large industrial facility, there are finance options that let you move ahead with solar now rather than delaying until cash is available.
