How We Design the Right Commercial Solar System
Every commercial site is different, so the first step is understanding how your business uses electricity and what space is available for solar.
Most commercial systems range from around 20kW for smaller businesses through to 100kW+ warehouse systems and 250kW+ installations for larger industrial sites, sized to match your energy usage and available roof or land space.
We also review available government incentives, such as STC rebates, which can reduce the upfront investment depending on system size and location.
Businesses can either purchase their solar system outright or use commercial solar finance to spread the investment while the system is already reducing electricity costs.
Every system is designed by our in-house engineering team to ensure the solar installation suits your building structure, electrical infrastructure, and operational energy demand.
#Government Incentives for Commercial Solar
Reduce the upfront cost of your commercial solar system with government rebates and incentives.
Check Your Small-scale Technology Certificate (STC) Eligibility
Most businesses installing solar systems up to 100 kW qualify for Small-scale Technology Certificates (STCs), which provide an upfront discount that reduces installation costs immediately. Many organisations may 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 may be eligible for — so you can see the savings from day one.

#Our Commercial Solar Quote & Installation Process
Sharp EIT Solutions delivers commercial solar 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.
2. System design & performance modelling
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 for your commercial solar installation, 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 commercial solar panel performance, and provide clear handover documentation so you know exactly what’s been installed and how it operates.
6. Monitoring & ongoing support options
We can provide monitoring for your commercial solar system and support options to help protect performance and quickly identify issues over time.

#Frequently Asked Questions About Commercial Solar
Commercial solar is solar power for commercial buildings and operations typically a commercial solar power system using commercial solar panels (solar PV) installed on rooftops, car parks, or as ground-mount. It reduces grid electricity use and can improve long-term energy costs and resilience. You can compare system types here.
Yes, we deliver commercial solar installation for businesses across Australia, from rooftop to car park canopies and larger site-based projects. You can view options by system type and system size.
Most businesses choose solar power for business to lower operating costs and reduce exposure to rising energy prices. A well-designed commercial solar power system can also improve energy independence and support sustainability targets, without changing day-to-day operations.
Savings depend on your energy use, tariff, and how much solar you can use onsite. Many businesses see meaningful reductions in electricity costs, especially when the system is sized for daytime loads and paired with options like battery storage (where it stacks up financially). You can see typical pricing factors on our costs page.
Sizing is based on your interval data (when you use power), available area (roof, car park or land), and network/approval constraints.
Commercial systems often start around 20kW and scale to 100kW and 250kW+ depending on the site, with industrial solar systems commonly sitting at the higher end. For large-scale ground mount, we also engineer solar farms from 500kW to 5MW. See common system sizes here.
They’re the same thing. “Commercial solar panels”, “commercial PV panels” and “commercial photovoltaic panels” all refer to solar PV modules used in business-grade systems.
We install commercial solar across multiple formats: rooftop, solar car park canopies, walkways, ground-mount and larger site-based systems—including Agricultural solar systems (AgriSolar) where it suits the operation and approvals. See system types here.
Sometimes, especially if your load profile matches solar production (daytime use) and the site can fit a larger system. Many businesses use commercial solar to cover a significant portion of demand and keep the grid for nights/peaks, and battery storage can further reduce grid reliance. See common system sizes here.
Timing depends on system size, access, switchboard works, and approvals. Smaller rooftop installs can be completed quickly, while larger commercial solar power installations (car parks, ground-mount, multi-site) take longer due to engineering and approvals.
Yes. Battery storage can help capture excess solar generation, manage peak demand and improve self-consumption—particularly for businesses with evening loads or demand charges.
Yes. Many commercial solar installations are designed so battery storage can be added later. The key is choosing compatible inverters/switchboard design and allowing space for future expansion.
Yes. EV charging can be integrated with commercial solar power so charging aligns with solar production. This can work for staff parking, customer charging or fleet depots, depending on site capacity and electrical design.
Often, yes. Eligible systems may access Small-Scale Technology Certificates (STCs) under certain sizes, and some projects may qualify for other programs depending on scale, location and network requirements. We’ll confirm what applies to your project during scoping. See cost considerations on our costs page.
Most commercial solar systems include manufacturer warranties on panels and inverters, plus a workmanship warranty on the installation. Exact coverage depends on the system design and the components selected. We’ll confirm the warranty terms in writing as part of your proposal so you know what’s covered and for how long.
