Commercial Solar System Costs
Commercial solar costs vary by system size, site conditions and equipment. But the upfront price is only part of the picture. Sharp EIT can help you understand the project cost, available incentives, projected savings, payback and estimated ROI before you invest.

What do commercial solar panels cost?
Commercial solar systems typically range from $650–$1,200 per kW installed, with larger systems generally achieving a lower cost per kW.
The final price depends on more than system size. Roof condition, electrical infrastructure, equipment selection, site access and network requirements can all affect the total project cost.
Available government incentives may also reduce the upfront investment. From 1 October 2026, the SRES will expand to eligible systems up to 1MW, potentially extending the upfront incentive to larger commercial projects.
For a more accurate figure, Sharp EIT can assess your site, electricity usage and system requirements to provide a detailed cost estimate.
Funding Options for Commercial Solar Systems

Understand Your Commercial Solar ROI Before You Invest
Sharp EIT can help you look beyond the installation price and understand the complete financial picture.
Led by Neil Armstrong, General Manager – Green Energy, our team can assess your project cost, available incentives, projected electricity savings, payback period and estimated return on investment.
This gives you a clearer understanding of what commercial solar could cost, save and return for your business before you decide to proceed.
#What Affects Commercial Solar System Cost?
No two commercial solar projects cost exactly the same. System size matters, but your site, electricity usage, infrastructure and project requirements can all influence the final investment. Understanding these factors upfront helps avoid unexpected costs and ensures the system is designed around the financial outcome you want to achieve.
- System size (kW)
Larger systems generally achieve a lower installed cost per kW through economies of scale. The right size depends on your electricity demand, available space and how much solar your business can use onsite.
- Operating hours & load profile
When your business uses electricity can be just as important as how much it uses. Matching solar generation to daytime consumption can increase savings, shorten payback and improve ROI.
- Roof type & site conditions
Roof structure, condition, access, shading and mounting requirements affect installation complexity. Sharp EIT assesses these factors before finalising the system design and project cost.
- Electrical & switchboard upgrades
Existing switchboards, metering and electrical infrastructure may require upgrades to support commercial solar. Identifying these requirements early helps provide a more accurate project budget.
- Grid connection & approvals
Network export limits, connection requirements and distributor approvals vary by site and system size. These can affect both project cost and delivery time.
- Engineering, design & monitoring
Good commercial solar design considers system performance, safety, compliance and long-term reliability—not simply how many panels will fit on the roof.
- Equipment, warranties & ongoing support
Panel and inverter quality, warranties and service support all affect upfront cost and long-term value. The lowest-priced equipment is not always the lowest-cost option over the life of the system.
- Battery Storage (Optional)
Adding battery storage increases the initial investment, but it may improve solar self-consumption, reduce peak demand costs or provide greater energy flexibility. We assess whether the additional investment makes financial sense for your site.

#Your Questions About Commercial Solar Costs
Commercial solar systems typically cost around $650–$1,200 per kW installed, depending on system size, site conditions, equipment and project complexity. Larger systems generally achieve a lower cost per kW due to economies of scale.
Available government incentives may also reduce the final project cost.
For a broader overview of system types and options, visit our Commercial Solar Solutions page.
Commercial solar costs generally decrease per kW as system size increases. Smaller systems may sit towards the upper end of the $650–$1,200 per kW range, while larger systems can benefit from economies of scale.
Final pricing also depends on roof conditions, electrical requirements, equipment selection and installation complexity.
Learn more about commercial solar system sizes.
Commercial solar installation costs vary depending on roof type, site access, structural requirements, electrical infrastructure and network connection requirements.
A straightforward rooftop installation will generally cost less than a project requiring switchboard upgrades, specialist access, structural works or additional grid-connection equipment.
