Is your Building Suitable for Rooftop Solar?
A commercial rooftop solar system is typically a strong fit if:
- Your business has consistent daytime energy usage
- Your roof has usable space with minimal shading
- The roof structure and access are suitable for commercial installation
- Your switchboard can support connection (or is upgradeable)
- You want to reduce operational overheads and improve cost certainty
- Even if you lease your site, rooftop solar may still be viable depending on lease term, approvals and energy profile.
Not sure? We can provide a feasibility review based on your bill and site details.

Monitoring and reporting add-ons
We’ll recommend the most practical option based on your goals — reducing cost, improving ROI, or future-proofing your energy strategy.
Solar System Sizes
#Find the Right Solar System Size for your Business
Below is a guide to common commercial solar system size bands. These examples are indicative only — the right fit depends on your energy profile, site constraints, and network requirements.
30kW – 75kW Commercial Solar Systems
Small to Medium Businesses
Solar systems in the 30kW–75kW range suit offices, retail, clinics, hospitality venues and smaller industrial sites with steady daytime energy use. This size is often chosen to maximise self-consumption and reduce reliance on grid power during business hours.
We’ll recommend the right fit based on your bill, operating hours and available roof space, then confirm what’s practical based on site constraints, compliance requirements and approvals so the system performs as expected.
100kW - 250kW Commercial Solar Systems
Growing Businesses
Systems in the 100kW–250kW range suit growing businesses with higher energy demand, including manufacturing, food and beverage, clubs, logistics, education and larger retail. This band is typically sized around daytime baseload to improve savings and cost certainty.
Design at this scale may also consider demand patterns, metering configuration and export limits. We’ll size the system around how your site uses energy and leave room to scale as your business grows.
250kW – 500kW Commercial Solar Systems
Designed for High-Load Commercial Facilities
The 250kW–500kW range is designed for high-load commercial and industrial facilities such as warehouses, processing sites, cold storage and larger manufacturing operations. These systems can deliver strong results when engineered around onsite usage rather than excessive export.
At this size, switchboard capacity, roof structure, network approvals and export constraints can influence design. We’ll tailor the system size to your load profile and confirm what’s achievable for your site.
500kW – 1MW Commercial Solar Systems
Built for Industrial-Scale Energy Use
Solar systems in the 500kW–1MW range suit industrial-scale energy use across distribution centres, multi-building sites, large manufacturing and high-throughput operations. This size band is often used to materially reduce grid reliance and improve long-term cost control.
Projects at this scale typically require detailed engineering and approvals, along with careful integration into existing electrical infrastructure. We’ll recommend a practical size and staging approach based on your operational needs.
1MW+ Commercial Solar Solutions
Engineered for Enterprise & Infrastructure Projects
1MW+ systems are custom engineered for enterprise and infrastructure sites with significant energy demand, including large industrial facilities, agribusiness and complex multi-site operations. This category can also include ground-mounted and solar farm-style projects (where approvals allow).
Design considerations can include multiple arrays, export management, compliance requirements and network approvals. We’ll work from your usage data and site constraints to recommend the right capacity and rollout path.
#Government Incentives for Commercial Solar
Reduce the upfront cost of your commercial solar system with Australian government rebates and incentives.
Most businesses qualify for Small-scale Technology Certificates (STCs), which provide an upfront discount that reduces your installation cost immediately. Many organisations can also benefit from instant asset write-off, accelerated depreciation and other tax-effective incentives.
Every solar proposal includes a clear breakdown of the rebates and incentives your business is eligible for - so you can see the savings from day one.
#Our Commercial Rooftop Solar Installation Process
Sharp EIT Solutions delivers commercial rooftop solar installation projects nationwide with an in-house engineering and delivery team. Our process is designed to minimise disruption to your business and ensure your commercial solar system performs long-term — not just on day one.
1. Feasibility & site assessment
We review your energy bills, operating hours, site constraints and goals to confirm the right commercial solar approach.

We design a commercial solar system matched to your load profile, tariffs and roof/land availability — including the right number and layout of commercial solar panels.
3. Approvals, compliance & grid connection
We manage required approvals, compliance checks and grid connection requirements so there are no surprises during install.
4. Commercial solar installation (minimal disruption)
Our team schedules works to suit your site — staged installation where needed to keep business running.
5. Commissioning, testing & handover
We commission the system, test performance, and provide clear handover documentation so you know exactly what’s been installed and how it operates.

Request a commercial solar assessment and we’ll share projected savings, options suited to your site and what the next steps could look like. Simple, clear information to help you decide.
#Your Questions About Rooftop Solar Panels for Busines Answered
Yes. Most commercial buildings can support solar panels on commercial rooftops if the roof structure, access and switchboard capacity are suitable. A quick site assessment confirms whether rooftop solar is viable and what system size makes sense.
Costs depend on system size, roof complexity, electrical requirements and site access. We provide quotes based on your bill and design requirements — not generic pricing.
Timeframes vary by system size and site constraints. Smaller systems may be completed quickly; larger projects are typically staged to minimise disruption.
Yes. We can design the system to be battery-ready and advise whether storage improves ROI now or later.
Monitoring and reporting options are available so your business can track performance and savings over time.
