Commercial Solar Systems

Commercial solar is a solar power system designed for businesses and commercial properties to generate electricity onsite and reduce reliance on grid power. Commercial solar systems typically use solar PV panels installed on rooftops, car park canopies or ground-mounted structures, with the system sized around the business's electricity usage, available space and operating hours.

Commercial solar power is electricity generated from solar PV panels installed on a business or commercial property — as opposed to a residential home. A commercial solar power system typically ranges from 20kW for smaller businesses to several megawatts for industrial facilities, and is designed to offset a significant portion of the business's grid electricity consumption during daylight hours.

Commercial solar electric systems are solar photovoltaic (PV) systems designed to generate electricity for commercial and industrial use. The term is used interchangeably with 'commercial solar systems' and 'commercial solar power systems'. They typically include solar panels, inverters, mounting structures, metering, and grid connection infrastructure — all designed and sized for a business's specific energy requirements.

Commercial and industrial solar both use solar PV systems to reduce grid electricity use, but industrial solar generally refers to systems designed for manufacturing, processing, warehousing and other energy-intensive operations. These sites often require larger systems because of their higher and more continuous electricity demand. Sharp EIT designs and installs commercial and industrial solar systems from 20kW through to multi-megawatt projects across Australia.

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.

Commercial solar savings depend on your electricity usage, tariff, operating hours, system size and how much of the solar power your business can use onsite. Businesses with high daytime electricity use generally achieve the strongest returns because more solar generation is consumed directly rather than exported. Sharp EIT models expected generation, annual savings and payback before installation so you can assess the financial case for your site. See our commercial solar costs page for typical pricing and payback factors.

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 commercial battery storage can further reduce grid reliance. See common commercial solar system sizes.

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 commercial solar system sizes.

Yes. Sharp EIT designs and installs commercial solar systems for businesses across Australia, from rooftop solar and car park canopies to ground-mount and multi-megawatt projects. Our commercial solar installation service covers site assessment, system design, savings modelling, approvals and grid connection, installation, commissioning and ongoing monitoring and support.

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 commercial solar system types.

Yes. Commercial Solar 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.

Yes. Sharp EIT offers commercial solar monitoring so businesses can track solar generation, electricity consumption and system performance. Monitoring can help identify faults or unexpected performance drops early and verify that the system is generating as expected. Monitoring options depend on the system design and equipment selected and can be included as part of your commercial solar proposal.

Commercial solar installation timelines depend on system size, site complexity, network approvals and any required electrical or structural works. Smaller rooftop systems can generally be installed more quickly, while larger industrial, car park and ground-mount projects require longer engineering and delivery programs. Sharp EIT confirms the expected approval and installation timeline during the site assessment, with works planned to minimise disruption to your business.

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.
