Benefits of Solar at your Business

Whether your goal is to reduce your business' operating expenses or meet sustainability targets, investing in commercial solar is a very sound investment. We have outlined the key benefits of installing solar on your business below:

• Cost Savings: Energy cost savings means lower overheads, and more money saved for your business.
• Government Support: Take advantage of incentives like Small-scale Technology Certificates (STCs) and Large-scale Generation Certificates (LGCs) that cut the upfront cost of going solar. The strongest financial case comes from using your own solar power during business hours rather than exporting it - feed-in rates are now low in most states.
• Tax Breaks: Commercial solar can generally be depreciated as a business asset, and smaller purchases may qualify for the small business instant asset write-off - talk to your accountant about the treatment that fits your purchase.
• Energy Freedom: Future proof your business from the constant energy price hikes by generating your own power, reducing reliance on the grid.
• Green Credentials: Showing your commitment to sustainability, aligns with the growing green expectations of customers and enhances your brand's reputation.
• Marketing Edge: Promote your business as eco-friendly, attracting environmentally conscious consumers.
• Property Value Boost: Increase the value of your property with solar panels, appealing to buyers looking for energy-efficient features.
• Risk Management: If your business opts for commercial solar batteries, diversifying your energy sources can allow you to stay operational during outages, and grid failures.
• Industry Leadership: By installing solar power, you are positioning your business as a leader, while giving yourself a competitive advantage, and inspiring others in your industry to follow suit.

Types of Commercial Solar Systems

Commercial solar systems come in various configurations, tailored to different business needs, location, and energy requirements. Here are the common system types:

Grid-Connected Solar Systems:

• Most common system installed commercially.
• Typically installed on the roof of the commercial premises.
• Directly connected to the electricity grid, allowing surplus power to be exported and imported as needed.
• Ideal for businesses looking to offset electricity costs, and reduce reliance on the grid.

Hybrid Solar Systems:

• Combine solar panels with battery storage and grid connection.
• Provide flexibility to store excess solar energy for use during peak times or grid outages.
• Optimal for businesses seeking both energy cost savings and backup power capabilities.

Off-Grid Solar Systems:

• Suitable for remote or rural businesses without access to the electricity grid.
• Battery storage is incorporated to store excess energy for use when solar generation is low.
• Offers energy independence but requires careful sizing and management.
• Can be installed with tilt-frames to track the sun's movement throughout the day, optimising panel orientation for maximum energy yield.

Solar Carports

• Solar carports are becoming increasingly popular for businesses with large parking areas such as airports and shopping centres.

Commercial Solar Rebates

The huge energy cost savings from installing solar are bolstered by significant rebates, and tax incentives tailored to businesses. Outlined below are key commercial solar rebates available in Australia, aimed at expediting the return on investment for businesses:

Federal Government Solar Rebates

The Federal Government's Renewable Energy Target encompasses two key schemes that incentivise the adoption of commercial solar power systems:

• Large-scale Renewable Energy Target (LRET)
• Small-scale Renewable Energy Scheme (SRES)

These schemes generate Large-scale Generation Certificates (LGCs) and Small-scale Technology Certificates (STCs) respectively, providing businesses with compelling reasons to invest in renewable energy solutions.

Small businesses adding battery storage can also access the federal Cheaper Home Batteries Program, which discounts eligible batteries paired with solar - support is tiered by usable capacity and applies to the first 50kWh.

Differentiating between LGCs and STCs: STCs are applicable to solar power systems below 100kW, whereas larger systems qualify for LGCs. While both offer avenues for reducing solar costs, businesses inclined to minimising upfront expenses typically favour STCs due to their immediate benefit in the form of a point-of-sale discount, unlike LGCs which are disbursed over time.

Phase-out of STCs and LGCs: The number of STCs a system earns falls each 1 January as the scheme's deeming period shortens by one year, and the reduction grows steeper every year until the scheme ends on 31 December 2030. The LRET also winds up at the end of 2030, and LGC prices have fallen sharply in recent years - so certificate income should be modelled conservatively in any proposal.

In other words, every day you put off installing a commercial solar system is costing your business thousands of dollars in potential rebates & energy savings.

Solar System Costs

The cost of commercial solar systems in Australia can vary depending on several factors, including the size of the installation, location, system components, installation complexity, and any additional features or services required. Commercial solar systems are often priced based on the cost per watt of installed capacity. Please use the following as a rough guide of commercial solar pricing.

Typical Cost per Watt (<30kW)

• As a guide, commercial installations under 30kW typically range from around $0.80/W to $1.10/W fully installed after STCs, though prices vary with installation location, state, roof type, quality of components and installation complexity.

Typical Cost per Watt (30-100kW) AKA 'The Sweet Spot'

• Larger systems generally benefit from economies of scale: commercial installations between 30kW and 100kW typically range from around $0.75/W to $1.05/W after STCs, with the per-watt cost usually falling as system size increases towards 100kW.
• Optional features such as battery storage, monitoring systems, and maintenance services can add to the overall cost of the system.

Typical Cost (100kW+)

• The cost of systems larger than 100kW varies greatly due to installation complexity, and engineering costs. Request a commercial solar proposal and we will match your request with our network of installers to provide an energy audit, and obligation free quotes.

For businesses considering solar, it's crucial to:

• Obtain quotes from reputable providers.
• Evaluate system specifications, and costs carefully.
• Ensure that the chosen solar installer optimises your energy tariff.
• Explore available incentives and financing options.

By following these steps, businesses can make an informed decision that aligns with their specific needs and budget.

Financing your Solar?

When considering your solar energy investment, you have three primary finance options: Capital Purchase (CapEx), Power Purchase Agreement (PPA), and Lease/Chattel Mortgage. Each of these options presents varying upfront costs, maintenance choices, and potential returns on investment.

A solar system can slash your organisation's energy costs, and businesses that purchase the system outright (CapEx) often see payback in roughly three to five years - though the actual return depends on your daytime usage, tariff, system price, and how the proposal is modelled.

Power Purchase Agreements (PPAs) and loans can also be structured in a way that offers cashflow positive outcomes from day one, making your CFO very happy indeed.

We dive into the benefits of each style of system financing on our dedicated commercial solar finance page.

Operation & Maintenance (O&M)

Under Australian Standards, your installer should supply handover documentation that includes recommended maintenance and servicing intervals. Great installers will often tailor-make an O&M schedule that they will typically conduct themselves.

Your Solar Quotes recommends having an electrical inspection conducted bi-annually, which often includes solar panel cleaning. A typical electrical inspection will involve examining inverters, protective and isolation devices, fuse enclosures, mounting structures, solar modules and connecting cables for signs of discolouration or degradation.

Obtaining Quotes

Accredited installers

Since early 2024, Solar Accreditation Australia (SAA) - appointed by the Clean Energy Regulator - accredits solar installers and designers, taking over that role from the Clean Energy Council (CEC). Using an SAA-accredited installer, with panels and inverters on the CEC approved product lists, is a legal requirement for claiming STCs - the federal solar incentive. It's also worth looking for NETCC Approved Sellers, a consumer-protection code that covers small-business customers and is administered by the CEC.
