Commercial solar systems for Sydney businesses

Most businesses use the bulk of their power in daylight hours, which is exactly when a rooftop system generates. We design commercial solar around your load profile, not a catalogue size.

Why go solar

Commercial solar power turns your roof into a fixed cost

Electricity is one of the few large overheads a business can actually reduce with a one off capital decision. Every kilowatt hour you generate on site is one you are not buying at a commercial tariff.

📉

Offset your daytime load

Offices, warehouses, workshops and retail sites draw their heaviest load between nine and five. Generation and consumption line up, so most of what you produce is used on site.

🏷️

Small-scale certificate discount

Systems up to 100 kW attract small-scale technology certificates, taken off the upfront price. We handle the calculation and the paperwork.

🛡️

Insulation from tariff rises

Commercial rates and network charges keep moving. The power you generate on your own roof is not exposed to either.

🔋

Commercial solar batteries

Store surplus generation for use in the evening or during peak periods, and reduce how much you draw from the grid when it costs the most.

📊

Performance you can report on

System monitoring gives you generation and consumption data you can put in front of a board, a landlord or a sustainability report.

🌱

Emissions reduction on the record

On site generation reduces your operational emissions, which increasingly matters in tenders and supply chain reporting.

The process

From site assessment to switch on

A straightforward four step journey, with one point of contact from design through to handover.

Free consultation

We review your bills and interval data, assess the roof, and work out how much of your load a system can realistically cover.

Design and proposal

You get panel and inverter selection, expected annual output, the certificate discount applied, and the assumptions behind the numbers.

Accredited install

Our SAA accredited team installs to Australian standards, scheduled around your trading hours, with network approval arranged.

Commission and monitor

We commission the system, hand over monitoring access, and stay available for performance checks and reporting.

Built for Sydney sites

Commercial solar installers who work around your operation

A commercial install in Sydney has to clear more than an engineering check. Ausgrid and Endeavour Energy both apply their own approval and export conditions, and the work still has to happen without shutting your site down.

  • System sized from your interval data, so the design targets self consumption rather than maximum export.
  • Export conditions confirmed with Ausgrid or Endeavour Energy before the design is locked in.
  • Roof structure, sheeting type and penetrations assessed, including Klip-Lok, trimdeck and concrete decks.
  • Installation staged around trading hours, deliveries and access constraints on tight industrial sites.
  • Leased premises supported, with the documentation your landlord will ask for.
Systems we have delivered

Commercial solar panels, specified and installed at scale

Three recent systems, with the equipment and output behind them. Every proposal is built for the site in front of us, so treat these as capability rather than a menu.

Systems up to 100 kW are eligible for small-scale technology certificates, which are deducted from the upfront price. The value depends on system size, location and the certificate price at the time of installation. Systems above 100 kW are treated differently and use large-scale generation certificates instead. Your proposal sets out which applies and what it is worth.

Good to know

Commercial solar questions, answered

How do I know what size system my business needs?+
It comes from your interval data rather than your roof area. We look at when you actually draw power across the day and the week, then size the array so most of the generation is consumed on site. A system that exports heavily earns far less than one that offsets what you would otherwise buy.
What incentives apply to commercial solar in NSW?+
Systems up to 100 kW attract small-scale technology certificates, applied as a discount on the upfront price rather than claimed back later. Larger systems fall under the large-scale scheme and are handled differently. We confirm which pathway applies to your site and what it is worth as part of the proposal, and we can talk through finance options at the same time.
Will the installation disrupt trading?+
Most of the work happens on the roof, away from your operation. Switchboard work and commissioning are the parts that need coordination, so we schedule those around your trading hours, deliveries and site access. You get a program before we start.
Can we add commercial solar batteries?+
Yes. Battery storage lets you hold surplus generation and use it in the evening or through peak periods instead of drawing from the grid. Whether it stacks up depends on your tariff structure and how much load sits outside daylight hours, which is something we assess rather than assume.
What if we lease the building?+
Leased sites are common and workable. You will need your landlord's consent, and they will usually want details on roof penetrations, structural loading and what happens at the end of the lease. We provide the technical documentation to support that conversation.
