The case for renewable energy equipment finance
Renewable energy equipment finance helps Australian businesses, farms and organisations pay for solar photovoltaic systems, battery storage, heat pumps, electric vehicle chargers, energy-efficient motors, LED lighting and other clean energy assets over time rather than with a single capital payment. Energy costs are a significant expense for manufacturers, cold storage operators, agricultural producers, hospitality venues and retailers. Investing in renewable energy can reduce exposure to grid prices and support sustainability commitments, yet the upfront cost can compete with other priorities. Financing spreads that cost so repayments can, in some cases, be partly offset by energy savings, although savings are never guaranteed.
Types of equipment commonly financed
- Rooftop and ground-mounted solar systems for commercial and industrial premises.
- Battery storage systems that store solar generation for use during peak price periods or outages.
- Heat pumps for water heating and space conditioning.
- Electric vehicle charging infrastructure and, in some cases, electric vehicles themselves.
- Energy-efficient equipment such as variable speed drives, compressors, refrigeration and lighting upgrades.
- On-farm systems such as solar pumping for irrigation and stock water.
Finance structures available
Chattel mortgage
Under a chattel mortgage, the business owns the equipment from the start and the lender takes security over it. Repayments may be structured with or without a final balloon payment. Ownership can affect how depreciation and GST are treated, which should be confirmed with a registered tax agent.
Finance lease
In a finance lease, the lender owns the equipment and leases it to the business for a set term, often with a residual value at the end. The business may have an option to buy the equipment, extend the lease or return it, depending on the agreement.
Operating lease or rental
Rental arrangements may include maintenance and allow upgrades. They can be useful for technology that changes quickly, though total costs may be higher over time.
Power purchase agreements
Under an on-site power purchase agreement, a third party installs and owns the system on the business's premises and sells the electricity generated to the business at an agreed price for a long term. The business avoids upfront capital costs but commits to buying power under contract terms. PPAs require careful legal review, especially for terms covering property sale, roof access and early termination.
Green or sustainability-linked loans
Some lenders offer discounted or specialised finance for eligible clean energy assets, sometimes supported by government-backed programs such as those historically involving the Clean Energy Finance Corporation. Eligibility rules and availability change, so businesses should check current offers directly.
Assessing the business case
Renewable energy equipment finance makes most sense when the business case is clear. Key steps include:
- Analysing at least twelve months of electricity bills and interval data to understand consumption patterns, peak demand and tariffs.
- Obtaining a system design that matches generation to on-site use, because energy consumed on site is often more valuable than energy exported to the grid.
- Modelling savings under several assumptions about electricity prices, system performance and degradation.
- Comparing the projected savings with finance repayments and the total cost of ownership, including maintenance, inverter replacement and insurance.
- Considering whether government incentives, such as small-scale technology certificates or state programs, apply and how they affect pricing.
Savings projections are estimates, not promises. Weather, tariff changes, equipment faults and changes in business operations can all alter actual results.
Documentation lenders commonly request
- Business details, including ABN, structure and directors.
- Recent financial statements and tax returns, or other evidence of trading history depending on the facility size.
- Supplier quotes, system specifications and installation details.
- Evidence of property ownership or landlord consent for installations on leased premises.
- Lodged business activity statements showing the business is up to date with its GST and PAYG obligations.
- Details of existing finance facilities.
For larger systems, lenders may want engineering reports, grid connection approvals and evidence that installers hold appropriate accreditations.
Leased premises and landlord considerations
Many businesses lease their premises, which creates complications. A landlord's consent is usually needed for roof-mounted systems, and the lease may need to address who owns the equipment, who maintains it, roof repairs and what happens at the end of the lease. Lenders may require the landlord to acknowledge their security interest. Aligning finance terms with lease terms helps avoid paying for equipment at premises the business no longer occupies. Some landlords install systems themselves and recover costs through green lease arrangements.
Alternatives to financing
Businesses can also pay cash, use an existing business line of credit, apply for grants where available, or join community energy arrangements. Some choose to reduce consumption first through efficiency measures, which can lower the size and cost of any renewable system. Others purchase renewable electricity through retail green power products without installing equipment. Each path has different costs, risks and control.
Costs and risks
Performance risk
Equipment may underperform due to shading, poor installation, dust, hardware faults or degradation over time. Warranties help, but claims can be slow, and a supplier that ceases trading may not honour them.
Technology risk
Battery technology and pricing are evolving quickly. Financing a system for longer than its useful life, or committing to equipment that becomes uneconomic, can leave the business repaying for outdated assets.
Regulatory and tariff risk
Changes to network tariffs, export limits, feed-in tariffs or incentive schemes can alter the economics of an installation.
Contractual risk
Power purchase agreements and leases often run for many years. Early termination fees, obligations on property sale and change of use clauses can be significant.
Security and guarantees
Equipment finance is usually secured by the equipment, but lenders may also ask for director guarantees. Removing equipment from a roof to repossess it is costly, so lenders consider the borrower's broader position too.
An illustrative scenario
Picture a hypothetical cold storage operator on the edge of Adelaide whose refrigeration runs day and night. Electricity is one of its largest costs. The business commissions an energy audit, which shows strong daytime demand and high peak charges. A solar installer proposes a rooftop system with battery storage.
The owners request separate quotes, ask for performance modelling under conservative assumptions and engage an independent engineer to review the design. They compare a chattel mortgage, a finance lease and an on-site power purchase agreement. Because they own the building and plan to stay for many years, they choose renewable energy equipment finance through a chattel mortgage with a term shorter than the expected life of the panels, and they add the system to their insurance policy. They also negotiate a maintenance contract and set up monitoring to compare actual generation against projections. This example is hypothetical; actual savings and finance terms depend on each project and lender.
Questions to ask suppliers, lenders and advisers
- What assumptions underpin the savings projections, and what happens if they are wrong?
- What warranties apply to panels, inverters and batteries, and who stands behind them?
- Which finance structure suits our ownership, tax and cash flow position?
- How does the finance term compare with the expected useful life of each component?
- What happens to the equipment and finance if we sell or vacate the premises?
- Are incentives or certificates already reflected in the quoted price?
- What maintenance is required, and who is responsible?
- Does the lender require landlord consent or additional guarantees?
Safeguards and repayment planning
Good safeguards include obtaining multiple quotes, verifying installer accreditations, insisting on clear warranties, installing monitoring systems, and insuring the equipment. Repayment planning should assume savings may be lower than projected in some years, so the business can still meet repayments from operating cash flow. Matching the finance term to the shortest-lived major component, often inverters or batteries, reduces the risk of paying for equipment after it needs replacement. Reviewing performance annually helps identify faults early and supports warranty claims.
Sizing the system to the business, not the roof
A common mistake is to install the largest system the roof can hold rather than the system the business can use. In many networks, energy exported to the grid earns relatively little compared with the cost of electricity bought from it, and some networks restrict how much a site can export. Oversized systems can therefore extend the payback period and leave the business repaying renewable energy equipment finance on generation it cannot use well. A system designed around measured daytime load, perhaps with battery storage to shift some solar output into evening periods, often produces a more reliable return. Where future electrification is planned, such as replacing gas equipment with heat pumps or adding electric vehicle charging for a delivery fleet, the design can allow for staged expansion so the business finances capacity as its demand grows.
Maintenance, monitoring and end-of-life planning
Clean energy assets are not set-and-forget. Panels benefit from periodic cleaning in dusty or coastal locations, inverters typically need replacement during the life of the panels, and batteries degrade with cycling and heat. A maintenance schedule, a monitoring platform that alerts the business to faults, and a reserve for component replacement help keep performance close to projections. Planning for the end of the asset's life also matters, including how equipment will be removed, recycled or replaced, and whether the finance agreement contains obligations at the end of the term such as a balloon or residual payment.
Linking finance to sustainability reporting
Larger businesses increasingly face customer, investor or regulatory expectations to measure and report emissions. Financing on-site generation and efficiency upgrades can contribute to those goals, and some lenders link pricing to sustainability outcomes. Businesses should ensure that any claims they make about emissions reductions are accurate and supported by data, because overstated environmental claims can attract regulatory scrutiny.
Frequently asked questions
Will savings cover the repayments?
Sometimes, but not always. Savings depend on usage, tariffs, system performance and weather. Businesses should plan to meet repayments even if savings fall short.
Can we finance solar on a leased building?
Often, with landlord consent and appropriate documentation. Lenders may require specific acknowledgements from the landlord, and the lease term should be considered.
Is a power purchase agreement better than buying?
A PPA avoids upfront cost and transfers performance risk to the provider, but it involves a long-term contract and may deliver lower lifetime savings. Ownership offers control but involves capital or finance commitments.
Are there government incentives?
Various federal, state and territory programs have offered incentives for renewable energy. Availability and eligibility change, so check current programs with official sources and qualified advisers.
Should batteries be financed over the same term as panels?
Not necessarily. Batteries and inverters usually have shorter expected lives than panels, so some businesses finance them separately or over a shorter term to avoid repaying for components that need replacing.
