Commercial Solar Systems Australia

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.
