Commercial Rooftop Solar Systems for Business
Every year Australian businesses pay thousands, sometimes hundreds of thousands in electricity costs before they make a single dollar of profit. Commercial rooftop solar changes that. And with government rebates still on the table, there's never been a better time to act.

Commercial and Industrial Rooftop Solar - Installed Across Australia
Less than 5% of commercial and industrial buildings in Australia have rooftop solar compared to nearly one in three homes. Businesses that act now lock in lower electricity costs for 25–30 years while government rebates are still available.
If your business is paying up to $5,000 a month in electricity, commercial rooftop solar will almost certainly stack up. Paying $10,000+ a month? The case for industrial rooftop solar is even stronger.
Sharp EIT designs and installs commercial and industrial rooftop solar systems for businesses of all sizes and types across Australia — designed around your operating hours, roof space, industry and energy use.

Should Your Business Add Battery Storage?
A commercial rooftop solar system works hardest during business hours, generating power while the sun is up, offsetting grid consumption in real time. Battery storage extends that window, capturing excess generation for evening use, reducing peak demand charges, and providing backup resilience when the grid goes down.
Whether batteries make financial sense now depends on your tariff structure, operating hours and how much power you use after dark. We'll tell you honestly with modelled numbers whether storage improves your ROI upfront or whether designing battery-ready now and adding storage later is the smarter move.
All Sharp EIT commercial rooftop installations are designed battery-ready as standard.
#Our Commercial Rooftop Solar Installation Process
Every Sharp EIT commercial rooftop project follows the same process, designed to minimise disruption to your business and ensure your system performs from day one, not just on paper.
1. Feasibility & site assessment
We review your energy bills, operating hours, roof structure, switchboard capacity and network export limits. You get a clear site-specific recommendation within a few days.
2. System design & performance modelling
Your system is sized around when and how your business uses power, not just roof area. We model projected savings against your actual tariff and load data so the numbers are real before anything is signed.
3. Approvals, compliance & grid connection
We manage network approvals, metering changes, compliance documentation and grid connection requirements end-to-end. Most projects are installation-ready within 2–8 weeks of approval.
4. Commercial solar installation
Most commercial rooftop installations take 1–5 days on site. We schedule works around your operations — staged installation where needed to keep your business running.
5. Commissioning, testing & handover
We commission and test the system, then hand over full documentation so you know exactly what's installed, how it operates and what performance to expect.
6. Monitoring & ongoing support options
Optional real-time monitoring so you can track generation, consumption and system performance — and identify any issues before they affect your savings.
#Commercial Solar Finance Options
The right commercial solar system pays for itself - the question is how you want to structure it. We offer $0 upfront finance, structured so repayments are typically offset by what you save on electricity from day one.
Options may include:
- $0 upfront finance — repayments offset by energy savings
- Outright purchase (CAPEX) with instant asset write-off available
- Accelerated depreciation on commercial solar installations
- Flexible structures to suit your cashflow and business goals
Every proposal includes clear cashflow modelling so you can see the financial impact before signing anything.

#Commercial Rooftop Solar - Your Questions Answered
Sharp EIT is a specialist commercial and industrial rooftop solar installer operating nationally. Our in-house engineering and installation team handles design, approvals, installation and commissioning across NSW, VIC, QLD, SA, WA, ACT and regional Australia. Every project is led by Neil Armstrong, our General Manager of Green Energy.
Commercial rooftop solar is a solar PV system installed on a business or industrial building to generate electricity for that site's own consumption. Unlike residential solar, commercial systems are engineered around business load profiles and sized to maximise offset of grid electricity during operating hours. See all commercial solar solutions.
Most commercial buildings are. Flat membrane, Colorbond, concrete tile and fibreglass roofs are all workable depending on condition, load capacity and access. What matters most is consistent daytime energy use and usable roof area. We confirm suitability quickly based on your bills and a site review — at no cost.
Typically $900–$1,200 per kW for smaller systems (20kW–50kW) and $750–$950 per kW for medium systems (50kW–250kW), before STC rebates. A 100kW system commonly costs $55,000–$75,000 after rebates. We provide fixed-price quotes based on your actual site — not industry averages. See a full breakdown on our commercial solar costs page.
Most commercial rooftop installations take 1–5 days on site. Grid connection approvals typically add 2–8 weeks before works begin, depending on your network and system size.
Most businesses achieve electricity cost reductions of 30–70% depending on system size, tariff structure and how much solar they can consume onsite during the day. A 100kW system generating approximately 140,000kWh annually can save $22,000–$30,000 per year depending on your electricity rate. We model your specific savings as part of the assessment — or see what commercial solar systems typically cost.
Most commercial roof types work well — including corrugated metal (Colorbond), flat membrane, concrete tile and fibreglass. Metal roofs are generally the most straightforward. We assess roof condition, load capacity and access during feasibility.
Yes. Industrial rooftop solar — warehouses, manufacturing, cold storage, logistics, food production — is a core part of what we do. Systems from 100kW to 500kW are common for industrial rooftops, designed around the continuous baseload usage patterns typical of those sites. See all commercial solar system types.
It depends on your load profile. If your business uses significant power after hours, carries high peak demand charges, or wants backup power resilience, batteries can materially improve your ROI. We design all systems battery-ready and will give you an honest modelled answer on whether adding storage now or later makes more financial sense. Explore commercial battery storage.
