As businesses look for ways to reduce costs and improve sustainability, one of the best options is adopting solar energy. In 2025, solar power is becoming an even more attractive choice for businesses in Australia looking to lower energy bills.

Solar for businesses is a great way to cut energy costs while contributing to a greener, more sustainable future. In this blog, we’ll explore how solar systems, particularly rooftop solar, can benefit your business and help you save money on electricity bills.

Why Solar Energy is a Smart Choice for Businesses

Solar energy is a renewable energy source that uses the sun’s power to generate electricity. As the price of electricity continues to rise, more Australian businesses are turning to solar power as a way to cut costs and reduce their reliance on the grid.

By installing solar panels for business use, companies can generate their own electricity, reducing the need to buy expensive energy from utilities.

One of the main benefits of installing solar systems for your business is the potential savings on energy bills. Solar panels allow you to harness free energy from the sun, which can significantly reduce your monthly electricity costs.

By using solar power, you can avoid paying high rates for energy from the grid and keep your energy bills under control.

Take Kew Golf Club, for example. Located in Victoria, this premier golfing destination has seen impressive financial and environmental benefits since adopting solar power with the help of Cyanergy.

The club now saves over $26,165 annually, cutting its electricity bills by 50% while generating clean, renewable energy.

After installing a 99kW solar system, Kew Golf Club’s annual energy costs dropped from $52,330 to $26,165.

Your business can achieve similar energy savings, just like Kew Golf Club, while taking the lead in sustainability and producing clean, renewable energy for the future.

How Does Rooftop Solar Work for Commercial Businesses?

Commercial solar power uses solar photovoltaic (PV) technology, which involves installing solar panels to turn sunlight into electricity. Rooftop solar is one of the most popular options for businesses looking to adopt solar power as it’s more cost-effective and solar helps to lower energy costs and reduce their environmental impact.

Commercial solar systems are larger than residential ones and can produce more energy. For example, a typical residential solar system in 2025 is around 6kW-13kW.

In contrast, commercial systems come in various sizes from 20kW-500kW, there are sizes available for small businesses to large.

Since commercial systems are bigger, they can accommodate more panels and generate more electricity, which is especially useful for businesses with higher energy needs or large rooftops.

However, commercial solar systems also come with higher installation costs and more complex setups compared to residential systems.

This is mainly due to the grid connection process and the need for special protection units if the system exceeds 30 kW of inverter capacity.

Recent advancements in solar PV technology have made commercial solar cells much more efficient. For example, Australian companies have developed some of the world’s most efficient commercial solar cells, with efficiency rates between 22% and 25% just ten years ago. This means businesses can now generate even more power from their solar systems.

Understanding commercial solar power means knowing the differences between residential and commercial systems. Factors like system size, energy output, and improved solar cell efficiency help businesses make informed decisions about using solar energy to meet sustainability goals and reduce costs.

The benefits of commercial solar power are clear: significant savings on energy bills, a reduced environmental footprint, and even a potential increase in property value, providing long-term returns on investment.

In some cases, any extra energy generated by the solar system can be sold back to the grid, allowing you to earn money through feed-in tariffs.

Feed-in tariffs are payments offered by energy providers for the electricity that your solar panels produce and send back to the grid.

This is an excellent way for businesses to not only save on energy bills but also earn extra income. Depending on the tariff rates in your area, this can add up to significant savings and revenue.

To ensure your solar system lasts and performs well, it’s important to choose the right equipment and work with a reliable solar installer.

How Much Are Solar Panels for Business?

The cost of installing solar panels for business use depends on various factors, including the size of your building, the energy needs of your business, and the type of solar system you choose.

On average, businesses in Australia can expect to pay anywhere from $12,999 to $73,000 for a commercial solar system.

However, it’s important to consider that the long-term savings on energy bills can make the initial investment worthwhile. Plus, there are government incentives and rebates available for businesses in Australia, which can help reduce the upfront cost of installation.

Over time, the energy savings will offset the installation cost, and your business can start seeing a return on investment.

Benefits of Solar for Business

Reduced Energy Bills: One of the main reasons businesses switch to solar energy is to lower electricity costs. With solar panels, you can produce your own electricity, reducing your need to buy from the grid.

Sustainability: Solar power is a clean, renewable energy source. By switching to solar, your business will reduce its carbon footprint and contribute to the fight against climate change.

Energy Independence: With solar power, you won’t be as dependent on energy suppliers. You’ll have more control over your energy costs, and during power outages, your solar system can continue to generate electricity if paired with batteries.

Increased Property Value: Installing solar panels can increase the value of your business property, making it more attractive to potential buyers or investors.

Government Incentives: Installing a solar system for your business can give you access to government rebates of up to $50,000! The Australian government encourages businesses to adopt solar energy, offering various rebates, subsidies, and loan options to reduce the cost of installing commercial solar panels and batteries.

A key program, the Small-scale Renewable Energy Scheme (SRES), makes rooftop solar systems more affordable. This program provides tradable certificates called small-scale technology certificates (STCs) for most commercial solar systems if the installer is accredited. The value of these certificates is based on your system’s expected electricity generation until 2030, depending on its size and your business location. Typically, you can transfer the STCs to your installer in exchange for a discount on your system.

Renewable Energy Concepts Can’t Violate the Laws of Physics

In the early days of 2GreenEnergy, my people and I were vigorously engaged in finding solid ideas in cleantech that needed funding in order to move forward.

I vividly remember a conversation with a guy in Maryland who was trying to explain the (ostensible) breakthrough that he and his team had made in hydrokinetics. When I was having trouble visualizing what we was talking about, he asked me to “think of it as a river in a box.”

“Oh!” I exclaimed. “You mean you take a box full of standing water, add energy to it get it moving, then extract that energy, leaving you with more energy that you added to it.”

“Exactly.”

I politely explained that the laws of physics, specifically the first and second laws of thermodynamics, make this impossible.

He wasn’t through, however, and insisted that, in his office, his people had constructed a “working model.”

Here’s where my tone descended into something less than 100% polite. I told him that he may think he has a working model, but he’s wrong; if he believes this, he’s ignorant; if he doesn’t, but is conducting this conversation anyway, he’s a fraud.

“But don’t you want to come see it?” he implored.

“No. Not only would not fly across the country to see whatever it is you claim to have built, I wouldn’t walk across the street to a “working model” of something that is theoretically impossible.”

—

I tell this story because the claim made at the upper left is essentially identical. You’re pumping water up out of a stream, and then claiming to extract more energy when the water flows back into the stream.

Of course, social media today is rife with complete crap like this. We’ve devolved to a point where defrauding money out of idiots is rapidly replacing baseball as our national pastime.
