Top 8 Benefits Of Solar Batteries For Businesses In Australia

In recent years, people around the world have become more aware of renewable energy, especially solar power. In Australia, the demand for sustainable energy has been growing to help fight climate change and global warming.  

Additionally, commercial solar batteries have developed quickly, making them an important and sometimes necessary addition to solar power systems. 

To understand it better, here are the top 8 benefits of solar batteries for businesses in Australia. 

What is a Solar Battery?

A solar battery is an extra component of your commercial solar panel system that stores the energy produced by your panels so you can use it later. Solar panels capture sunlight and turn it into electricity, which is then used in your home through a solar inverter.  

If your solar power system is connected to the power grid, any extra energy goes to the grid in a process called “net-metering.” It gives you credit on your next electricity bill, lowering your payment if you need power from the grid.  

However, if you have an off-grid solar system, it is highly recommended to store excess energy in a solar battery. This way, the extra energy you generated earlier is available as backup power when your solar panels aren’t producing enough energy. 

Cost of Solar Batteries Used for Commercial Purposes

The cost of a commercial solar panel system with commercial solar batteries in Australia can vary significantly based on factors such as system size, quality of components, installation complexity, and location. Here are the approximate costs for such systems in Australia: 

1. Solar Panels:

Total Cost: AUD 350,000: AUD 1,250,000 

Very Large Commercial System (500 kW and above with batteries): 

Total Cost: AUD 1,250,000 and up  


  • Government Incentives: Australia offers various incentives, rebates, and grants for renewable energy projects that can significantly reduce costs. 
  • Quality of Components: Higher quality panels and batteries may cost more upfront but offer better efficiency and longevity. 
  • Site-Specific Factors: Installation complexity, local regulations, and specific site conditions can affect overall costs.

Solar System Size for Commercial Purpose

The best rooftop solar system size for your business depends on how much electricity you use when you use it, your budget, and the amount of sunny roof space available for the solar panels. In some areas, regulations may also limit the system size. 

Using a solar and battery calculator, you can get a recommended system size for your business. For small businesses, Cyanergy recommends a system size that will pay for itself in about 5 years.  

The actual payback period depends on many factors, including weather, maintenance costs, and future electricity prices. 

For businesses with high electricity use, Cyanergy recommends the largest system size that allows at least 80% of the generated power to be used within your business. 

This is because some businesses, especially those with high electricity use, may need help to get an electricity pricing plan that offers credit for electricity sold back to the grid via a feed-in tariff.  

So, it might make sense to install a system size that allows you to use most of the solar power on-site.  

What to Look for in a Commercial Solar Battery

You need to consider several factors when choosing one. Here are some key things to look for: 

Power Rating

The power rating tells you how much power a battery can provide at once, measured in kilowatts (kW). This rating indicates how many and what types of appliances the battery can power.  

For example, a small LED light uses less than 10 Watts, while a large air conditioner uses about 4.8 kW. Most solar batteries can continuously provide around 5 kW of power.  

There are two types of power ratings: continuous (steady power) and instantaneous (short bursts of power), which are important for appliances that need a lot of power to start up.  

Battery Size

Battery size refers to its storage capacity, or how much electricity it can hold, measured in kilowatt-hours (kWh). This shows how long the battery can power your home.  

For instance, a 10 kWh battery can power a 10-watt light for over 40 days but can only run a 4.8 kW air conditioner for two hours.  

Larger-capacity batteries are usually bigger, but lithium-ion nickel manganese (NMC) batteries offer high storage in a smaller space if you have limited room.  

Battery Lifetime

A battery’s lifetime is measured by its lifespan, total throughput (total electricity it can handle), and cycles (how many times it can be recharged).  

Throughput and cycles are like a car’s mileage warranty. For example, a 10 kWh battery with a 20,000 kWh throughput can be recharged about 2,000 times, equating to roughly one cycle per day for five and a half years. 

Battery Safety

To be certified for home or business use, all solar batteries must meet specific safety standards. Battery storage systems help you save more on electricity and rely less on the power grid.  

Top 8 Benefits of Solar Batteries for Businesses in Australia

Backup Power in Case of Outages: Ensuring Business Continuity

Commercial solar batteries provide a reliable backup power source during grid outages, which is essential for businesses that need continuous operations like data centers, hospitals, and factories.  

By storing extra solar energy, your business can switch to battery power during an outage, preventing disruptions and financial losses from downtime. This capability increases your business’s reliability and gives stakeholders confidence in your operations. 

Asset for Your Business: Long-Term Value

In addition to immediate benefits, commercial solar batteries are valuable assets for businesses. As technology improves and sustainability becomes more important, having a solar battery system increases your business’s value and appeal.  

Additionally, as energy storage technology advances, businesses can upgrade or expand their existing solar batteries, keeping their investment up-to-date and adaptable to future energy needs. 

Reduce Your Electricity Bills

With solar batteries, you can save the extra electricity your solar panels make during the day. You can use this stored energy in the evening or on cloudy days, which means you don’t need as much power from the grid, and your electricity bills will be lowered.  

Protect Your Business from Electricity Price Rises

Electricity prices can go up and down and often get more expensive over time. Using solar batteries makes your business more self-sufficient because you don’t need to rely on the grid as much. This helps you avoid the impact of rising electricity costs and keeps your energy expenses more stable and predictable.  

Reduce the Cost of Charging Electric Vehicles

Charging electric vehicles (EVs) from the grid can be pricey. With solar batteries, you can store solar energy during the day and use it to charge your EVs at a lower cost, making it cheaper to run your electric vehicles.  

Help Reduce the Cost of Getting Off Gas and Eliminate Gas Bills

Switching from gas to electric systems can be expensive because electricity is costly. By using solar batteries to store and use your solar energy, you can reduce or even eliminate your need for gas, lowering gas bills and the costs of switching to electric systems. 

Unlock Tax Incentives for Your Business

Many governments give tax breaks, rebates, and grants to businesses that invest in renewable energy like solar batteries. By installing a solar battery system, your business can benefit from these financial incentives, making the installation cost less. 

Significantly Reduce Your Business’s Greenhouse Gas Emissions

Using solar batteries helps your business use cleaner, renewable energy and less fossil fuel. This greatly cuts down your greenhouse gas emissions, making the environment greener and helping your business achieve sustainability goals. 

Some Extra Benefits You Can Enjoy

No Noise Pollution

Solar batteries are not only good for the environment but also very quiet. They work without making any noise, so they don’t disturb the surroundings of a commercial area. This makes them a great addition to any business’s solar panel system.  

Environment-Friendly Corporate Image

Using solar batteries to save solar power for future use helps businesses continue their green efforts, benefiting everyone involved in the long run. Plus, adopting solar and battery systems can improve the company’s green image and enhance customer perception. 

High Energy Efficiency

The efficiency of commercial solar batteries is based on how much energy they store and convert into usable electricity. High energy efficiency means the business gets more out of the energy, leading to better productivity and outcomes over time.
