Why Sharp EIT for Commercial Solar?

Why Sharp EIT for Commercial Solar?

A commercial rooftop solar system needs to work with more than your electricity usage. The building itself, available roof area, structural capacity, electrical infrastructure and network requirements all influence the final design.

Sharp EIT manages the complete commercial rooftop solar project, from initial site and energy assessment through to engineering, approvals, installation and ongoing monitoring.

Our approach includes:

  • Site and electricity usage assessment
  • Roof layout and available installation area
  • Structural and electrical requirements
  • Commercial solar system design and performance modelling
  • Network applications and grid connection
  • Installation, commissioning and monitoring

Every system is designed around the site and how your business uses electricity, rather than simply installing the maximum amount of solar that will fit on the roof.

#Our Commercial Rooftop Solar Installation Process

Every commercial rooftop solar project starts with understanding your building and energy usage. Sharp EIT manages the process from site assessment and system design through to approvals, installation, commissioning and ongoing monitoring.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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 Rooftop Solar - Your Questions Answered

Who installs commercial and industrial rooftop solar in Australia?

Sharp EIT designs and installs commercial and industrial rooftop solar systems Australia-wide. Our team manages site assessment, engineering, system design, network approvals, installation, commissioning and ongoing monitoring for commercial projects from 20kW through to multi-megawatt installations.


What is commercial rooftop solar?

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.


Is my commercial building suitable for rooftop solar?

Suitability depends on your available roof area, roof condition, structural capacity, orientation, shading, access and existing rooftop equipment, as well as your electricity usage and electrical infrastructure.

Sharp EIT assesses these factors as part of the feasibility process before recommending a commercial rooftop solar system.


Can I get rooftop solar if I lease my premises?

Possibly. If your lease term is long enough and landlord approval can be obtained, commercial rooftop solar on a leased site can still be viable. We can advise on what's needed based on your specific situation.


How much does commercial rooftop solar cost?

Commercial rooftop solar systems typically cost around $700–$1,200 per kW installed after applicable incentives, with larger systems generally achieving a lower cost per kW.

Actual pricing depends on system size, roof condition, electrical infrastructure, equipment, site access and network requirements.

For indicative pricing and the factors that affect project cost, see our Commercial Solar System Costs guide.


How long does a commercial rooftop solar installation take?

Installation time depends on the system size, roof and site conditions, electrical works and project complexity. Smaller commercial rooftop installations may be completed within several days, while larger systems can require staged works over a longer period.

Network approvals and grid connection requirements can also affect the overall project timeline.


How much can a business save with commercial rooftop solar?

Savings depend on your electricity usage, operating hours, electricity tariffs, system size and how much solar generation your business can consume onsite.

Sharp EIT models projected solar generation and electricity savings using your actual energy profile so you can understand the expected financial return before proceeding.

For indicative system pricing, payback and ROI information, see our Commercial Solar System Costs guide.


What roof types are suitable for commercial solar panels?

Commercial solar panels can be installed on many common commercial roof types, including metal roofing, flat membrane roofs and other suitable roof structures.

Roof condition, structural capacity, available installation area, shading, access and existing rooftop equipment are assessed during feasibility to determine the appropriate mounting and system design.


Do you install rooftop solar for industrial sites?

Yes. Sharp EIT designs and installs industrial rooftop solar systems for warehouses, manufacturing facilities, cold storage, logistics, food production and other energy-intensive sites.

Industrial systems are designed around the site's load profile, available roof area, electrical infrastructure and network requirements, with projects ranging from commercial-scale systems through to multi-megawatt installations.


Should I add battery storage to my rooftop solar system?

It depends on your energy profile and what you want the battery to achieve. Battery storage may be worth considering where your business has excess daytime solar generation, high peak demand charges, significant electricity use outside solar-generating hours or a requirement for backup power.

Sharp EIT can model solar and battery storage together to determine whether adding storage now or in the future improves the business case.


Do you install commercial rooftop solar Australia-wide?

Yes. Sharp EIT delivers commercial rooftop solar installations nationally — NSW, VIC, QLD, SA, WA, ACT and regional areas. Our in-house team travels for commercial projects.
