Switching to solar power offers significant financial and environmental benefits for businesses, but the upfront costs of commercial solar installation can be substantial. That’s where commercial solar financing options come into play. For companies interested in adopting renewable energy without straining their budgets, a reliable commercial solar company can offer flexible financing solutions tailored to their needs. In this guide, we’ll explore the various financing options available, helping you make informed decisions when working with a commercial solar company.
Key Points
- Businesses can finance commercial solar through a power purchase agreement, a solar lease or a green loan.
- A power purchase agreement needs no upfront cost. A third party owns the system and you buy its power at an agreed rate.
- Owning the system, with cash or a green loan, lets you claim depreciation and the certificate value.
- Small-scale Technology Certificates cut the upfront cost of systems up to 100 kW, and up to 1 MW from 1 October 2026.
- Small businesses with an aggregated turnover under $10 million can write off eligible assets costing less than $20,000 in the year they are installed.
Why Financing Matters for Commercial Solar Projects
Commercial solar financing enables businesses to manage the initial investment required to install solar systems, making solar more accessible to a wide range of industries. With financing, companies can enjoy the benefits of solar energy immediately while spreading the cost over time, preserving capital for other investments. Collaborating with an experienced commercial solar company ensures you understand the financial implications and find the right financing structure for your project.
Types of Commercial Solar Financing Options
When financing a solar project, businesses have multiple options to choose from, each with distinct advantages. Here are the most common types of financing available from a commercial solar company.
1. Solar Power Purchase Agreement (PPA)
A Power Purchase Agreement (PPA) is a popular financing option where a third party finances and owns the solar system. The business agrees to purchase the electricity produced by the system at a predetermined rate, often lower than utility rates. PPAs offer:
- No upfront costs, as the third-party owns and maintains the system.
- Fixed energy rates, which can provide long-term savings.
- Low-risk entry, making it ideal for companies interested in renewable energy without significant capital investment.
2. Solar Lease
A solar lease allows businesses to install a solar system by paying a fixed monthly fee. Under this arrangement, the commercial solar company instals and owns the system, and the business gains access to solar power without purchasing the system outright. Solar leases are attractive because:
- They require minimal upfront costs.
- Payments are predictable, making budgeting easier.
- They provide access to the benefits of solar without ownership responsibilities.
3. Green Loans
Many financial institutions offer green loans specifically for renewable energy projects. These loans typically come with favourable interest rates and terms for energy-efficient upgrades. By working with a commercial solar company experienced in financing, businesses can obtain a green loan tailored to their needs. Green loans provide:
- Flexible terms to match cash flow and project scope.
- Potential tax benefits from renewable energy incentives.
- Ownership of the system, allowing the business to claim depreciation and the certificate value.
Tax Incentives and Rebates for Commercial Solar
Australian businesses can cut the cost of commercial solar through federal certificates and tax deductions. The right mix depends on your system size and your business turnover.
Small-scale Technology Certificates (STCs)
STCs give you an upfront discount on systems up to 100 kW. Your installer claims the certificates and takes their value off your invoice at the point of sale. From 1 October 2026 the scheme expands to systems up to 1 MW, so most mid-scale commercial solar systems will qualify for the same discount. The Clean Energy Regulator expects to open applications for these larger systems in mid to late November 2026.
Large-scale Generation Certificates (LGCs)
Systems too large for STCs can earn LGCs instead. They are accredited as power stations under the Large-scale Renewable Energy Target. Each megawatt-hour the system generates creates a certificate you can sell. That gives you income over the life of the system rather than an upfront discount.
Depreciation and the instant asset write-off
A commercial solar system is a depreciating asset, so you can deduct its cost over its effective life. Small businesses with an aggregated turnover under $10 million can use simplified depreciation. Eligible assets costing less than $20,000 can be written off in full in the year they are installed. More expensive assets go into the small business pool. Your accountant can confirm how this applies to your business.

Partnering with a Commercial Solar Company for Design & Engineering
Choosing the right commercial solar company goes beyond financing. A comprehensive solar provider should offer design and engineering services to ensure that your system is optimised for maximum efficiency and return on investment. Proper design is essential for achieving desired savings and performance.
Customised Solutions
A reputable commercial solar company will assess your energy needs, location, and budget to create a customised system design. With thorough planning and engineering, your solar project will align perfectly with your business goals and facility requirements.
Project Management
From initial consultation to project completion, your commercial solar company should provide transparent and effective project management. Clear communication and milestone tracking are vital for keeping the installation on schedule and within budget.
Evaluating Long-Term Financial Benefits
The long-term financial benefits of commercial solar are one of the main reasons why more businesses are choosing renewable energy. Partnering with a commercial solar company to install a solar system can result in:
- Reduced Energy Bills: By generating your own electricity, you can reduce reliance on grid power and significantly cut utility costs.
- Increased Property Value: Properties with solar installations often see increased market value, making it a strategic investment.
- Sustainability and Corporate Responsibility: Demonstrating a commitment to sustainability can enhance your brand reputation and appeal to eco-conscious customers.
A commercial solar company can help you calculate potential savings and determine the most cost-effective way to implement solar in your business.

Frequently Asked Questions
Can my business get commercial solar with no upfront cost?
Yes, through a power purchase agreement or a solar lease. A third party pays for and owns the system. You pay for the power it produces, or a fixed monthly fee, instead of the purchase price.
Which financing option lets my business claim the tax benefits?
Owning the system, with cash or a green loan. The owner of a system claims its depreciation and the certificate value. Under a power purchase agreement or a lease the provider owns the system, so those benefits stay with the provider. Lease payments are usually deductible as a business expense, so confirm the treatment with your accountant.
Do commercial solar systems qualify for STCs?
Yes. Systems up to 100 kW qualify now, and systems up to 1 MW qualify from 1 October 2026. Your installer claims the certificates and takes their value off your invoice. Larger systems can earn Large-scale Generation Certificates instead.
Can I use the instant asset write-off for solar?
Yes, if your business has an aggregated turnover under $10 million and the system costs less than $20,000. A system costing $20,000 or more goes into the small business depreciation pool instead. Your accountant can confirm how this applies to your business.
How do I choose the right financing option?
Start by deciding whether you want to own the system. Owning it gives you the depreciation, the certificate value and all of the savings. A power purchase agreement or a lease keeps cash in the business but shares the savings with the provider. Solar Set compares the options for your site as part of your proposal.
