Adelaide's commercial solar installers.Eliminate your biggest energy cost.

South Australian businesses are paying more for electricity than almost anywhere else in the world. A commercial solar system turns that overhead into an asset, and starts paying back from the first month.

Why commercial solar

Electricity is one of your biggest controllable costs. Here's how to take control of it.

South Australian businesses face some of the highest commercial electricity tariffs in the world. With coal plants closing and grid infrastructure costs being passed down the line, those rates aren’t coming down. For small to medium enterprises, energy costs can be the margin between profit and loss.

A well-designed commercial solar system generates electricity during the hours your business actually consumes it, which means instead of buying power from the grid at peak commercial rates, you’re using energy you’ve already produced at effectively zero marginal cost. The financial case is straightforward: the system pays for itself, then keeps generating returns for 25+ years.

Beyond the bottom line, going solar sends a clear signal to your customers, staff, and suppliers. Corporate sustainability isn’t a tick-box anymore. It’s an expectation. And in South Australia, where solar penetration is among the highest in the world, a business without solar is increasingly the exception.

Who we work with

From small offices to large industrial sites: we design for your load profile.

Commercial solar isn’t one-size-fits-all. The right system depends on when your business consumes power, what your roof can carry, and what your goals are. We work across every business type.

Offices & Professional Services

Daytime power consumption aligns perfectly with solar generation. Offices, medical practices, law firms, and accounting businesses typically see the fastest payback periods of any sector.

Retail & Hospitality

High air-conditioning loads, refrigeration, and lighting make retail and hospitality some of the highest electricity consumers per square metre. Solar cuts directly into those peak daytime costs.

Manufacturing & Warehousing

Large roof areas, consistent daytime operations, and significant machinery loads make industrial facilities ideal solar candidates. We design systems from 20kW to hundreds of kilowatts.

Schools & Education

Schools operate during peak solar hours and often have large roof areas across multiple buildings. Community and government funding pathways may also apply, improving the economics further.

Healthcare & Aged Care

Facilities that run around the clock have the most to gain from solar paired with battery storage. Reduce peak-rate consumption by day, draw on stored power overnight, and protect critical operations from outages.

Strata & Commercial Property

Commercial property owners can install solar to offset common area electricity costs, reduce operating expenses, and increase property appeal and value for tenants, a proven competitive differentiator.

The business case

Why the numbers work: for businesses of every size.

Commercial electricity rates in SA are among the highest in the world. That’s the problem. Solar fixes it permanently, and the financial case gets stronger the more power your business uses.

Generate power at zero marginal cost

Once installed, your solar system generates electricity at effectively no ongoing cost. Every unit generated during business hours directly offsets power you'd otherwise purchase at commercial rates, often 30–40c per kWh.

Government STCs reduce your upfront cost

The federal Small-scale Technology Certificate (STC) scheme provides a point-of-sale discount on commercial systems. Larger systems generate more STCs, we calculate and apply this in your quote automatically.

Instant depreciation under tax legislation

Under current tax rules, eligible businesses can claim an immediate deduction for the full cost of a solar system in the year of installation. This materially improves the effective payback period, ask your accountant.

What we deliver

A complete commercial solar service: designed, installed, done.

We manage the entire project from energy assessment through to grid connection and handover. No third parties, no coordination headaches.

Energy load analysis

We review your actual consumption data and identify when and where your business uses power most. System size and configuration are built around your real load profile, not a template.

Custom system design

Site assessment, roof structural check, shading analysis, and string layout, all done before we quote. We install AIKO and Risen Energy commercial solar panels paired with Fronius, GoodWe, Sigenergy or Sungrow inverters, chosen for performance and reliability. You see the full design before committing to anything.

Fully in-house installation

Our own SAA accredited team handles every installation. We work around your operating hours to minimise business disruption, and our project manager keeps you updated throughout.

All approvals & compliance

SA Power Networks applications, council permits where required, STC registration, export limit agreements, and metering upgrades, we handle all of it. You sign where needed, we do the rest.

Battery storage integration

Pair your commercial system with Sigenergy battery storage to capture surplus generation and deploy it during peak-tariff periods. We model the battery economics separately so you can see the payback clearly.

Performance monitoring & reporting

Every commercial system includes inverter monitoring with real-time generation data, exportable for your sustainability reporting or financial records. We configure it for you at handover.

Recent project

20kW solar + 48kWh battery: Adelaide CBD business.

This commercial installation in the Adelaide CBD features 20kW of solar paired with 48kWh of Sigenergy battery storage. The system was designed specifically to help this business reduce grid reliance, store excess solar production during the middle of the day, and manage rising peak-tariff energy costs in the evening.

Clean installation, smart energy management, and built with room to scale, a benchmark for what commercial solar looks like when it’s done properly.

Common questions

What business owners ask us before going solar.

How large a system does my business need?

It depends entirely on your electricity consumption and when you use power. A small office might suit a 10–20kW system; a warehouse or manufacturing site might need 100kW+. We analyse your actual bills before recommending anything.

What government incentives are available for businesses?

The federal STC scheme provides an upfront discount on qualifying commercial systems. Additionally, under current tax legislation, eligible businesses may be able to immediately depreciate the full system cost in the year of installation. We apply STCs in your quote; talk to your accountant about depreciation.

What happens if we expand or move premises?

Solar systems can be expanded by adding more panels or battery capacity as your needs change. If you own the property, the system adds to its value. If you lease, we can discuss portable or transferable options depending on your lease terms. This is worth raising with us at the quote stage.

How much does commercial solar cost in Adelaide?

It depends on system size, roof or ground-mount conditions, and your business's load profile. We provide a free, no-obligation quote after an energy load analysis, typically within 48 hours, factoring in available STC incentives and instant asset write-off depreciation.

Will installation disrupt my business operations?

We plan installation carefully around your schedule. Most commercial systems are completed in one to three days. We work with your operations team to minimise any disruption, and brief interruptions to power are kept to a minimum and scheduled in advance.

Does solar work for businesses that operate at night?

Yes. With battery storage. A Sigenergy battery system stores surplus solar generated during the day and discharges it during evening operations. We model the battery economics separately so you can see exactly what the addition of storage adds to the payback calculation.

Who handles the grid connection and compliance paperwork?

We do. SA Power Networks applications, export limit agreements, metering upgrades, council permits where required, and STC registration are all handled by our team. You receive a compliance pack at handover with every certificate and approval document.

Do commercial solar systems need ongoing maintenance or servicing?

Yes, though less than most people expect. Panels have no moving parts and generally just need an occasional clean and visual check, particularly on flat or low-pitch commercial roofs where dust and debris build up faster than on a typical home. The inverter is the component most likely to need attention over the system's life. Solar panel repairs and maintenance is an active part of what we do, so if your system starts underperforming, you call the same local team that installed it.
