Commercial Solar System Payback Period In Australia
Maximize savings with commercial solar!
Typical Payback Period for Commercial Solar in Australia
On average, the payback period for commercial solar panel systems in Australia ranges from 3 to 5 years, depending on different factors such as the system size, electricity usage, and government incentives. Here’s a quick breakdown
Small Systems (10kW)
- Suitable for small businesses with low energy consumption (e.g., offices).
- Payback period: 4–5 years.
Medium Systems (20–50kW)
- Ideal for medium-sized businesses like gyms, cafes, and small manufacturers.
- Payback period: 3–4 years.
Large Systems (50–100kW )
- Best for energy-intensive industries like warehouses, logistics.
- Payback period: 3 years or less.
Factors Affecting the Payback Period
1
Electricity Costs
The higher your electrical energy prices are, the more financial savings your business can achieve. With Australia’s climbing electrical power rates, services profit considerably from producing their very own power.
2
Energy Consumption
Businesses with high daytime energy usage—such as those running manufacturing equipment or operating refrigeration units—can use more solar power directly, reducing reliance on grid electricity and shortening the payback period.
3
System Size and Installation Costs
Larger systems frequently have lower cost-per-kilowatt-hour and create more energy, yet they require greater ahead-of-time financial investments. Matching system dimensions with service power is vital for ideal savings.
4
Government Incentives
Programs like the Small-scale Technology Certificates (STCs) and Large-scale Renewable Energy Target (LRET) provide financial benefits that lower installation costs, reducing the payback period.
5
Feed-in Tariffs
Businesses can sell excess solar energy back to the grid in some areas, creating an additional revenue stream that accelerates ROI.
6
Location and Solar Irradiance
Businesses located in areas with higher solar exposure, such as Queensland or Western Australia, benefit from increased energy production, reducing the time needed to recover costs.
Example Payback Period For Commercial Solar Calculation
Let’s consider a practical example:
- System Size: 50kW
- Installation Cost: $50,000
- Annual Energy Savings: $16,000
- Government Rebates: $5,000
- Total Investment: $50,000 (minus $5,000 rebate = $45,000 net cost).
- Annual Savings: $16,000.
Payback Period:
Payback Period = Total Investment ÷ Annual Savings
Payback Period = $45,000 ÷ $16,000 = 2.8 years.
After 2.8 years, this business will enjoy almost free electricity for the remaining years from the lifespan of the system, which typically lasts 25+ years.
Long-Term Benefits Beyond Payback
Significant Lifetime Savings
A commercial solar system can save businesses hundreds of thousands of dollars over its lifetime. For example, a 100kW system with a life expectancy of 25 years can save $500,000 or more, relying on electricity costs.
Energy Independence
Generating your own electricity reduces dependency on fluctuating electricity prices.
Environmental Impact
Solar power mines carbon exhausts and assists companies in satisfying sustainability goals, which is significantly important for stakeholders and consumers.
Is Solar Worth It for Australian Businesses?
Absolutely. With short payback periods, attractive incentives, and long-term savings, commercial solar is one of the smartest investments Australian businesses can make. After the system pays for itself, businesses enjoy decades of free electricity, reduced operational costs, and a competitive edge in the marketplace.
Take control of your energy future by investing in commercial solar today. With rising electricity prices and dwindling government rebates, there’s no better time to make the switch.
