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.

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.

The terms are often used interchangeably. 'Industrial solar' typically refers to larger-scale systems — generally 250kW and above — installed for manufacturing, processing, or heavy industrial operations with high and continuous electricity demand. 'Commercial solar' covers the broader range from small businesses (20kW) through to large commercial and industrial installations (1MW+). Sharp EIT designs and installs both commercial and industrial solar systems 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.

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.

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.

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.

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.

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.

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.

Yes. We offer monitoring options for commercial solar systems so you can track generation, consumption, and system performance in real time. Monitoring allows early identification of faults or performance drops — protecting your investment and ensuring your system continues delivering the savings it was designed for. Ask about monitoring options when requesting your assessment.

Most rooftop commercial solar installations take 1–5 days on site. Approvals and grid connection add 2–8 weeks before installation begins. Car park canopies and ground-mount projects have longer installation windows — we'll confirm your specific timeline during feasibility.

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.
