Commercial solar in Wollongong
The Illawarra coast enjoys reliable sunshine, and with rising grid prices, Wollongong homes are well placed to benefit from solar and battery storage. We service the region from our nearby Smeaton Grange office.
You get a genuinely local team, with install teams based right through QLD and NSW — We design commercial systems around your business’s daytime load and tariff. Larger systems usually run on three-phase power, and we confirm your connection type and network export rules as part of the design — so the system is sized to what genuinely benefits your business.

Commercial Solar in Wollongong — Common Questions
How is commercial solar different from residential?
Commercial systems are larger, often require three-phase power, and are designed around your business's daytime load and tariff. The financial case also differs — businesses can benefit from reduced operating costs and potential tax treatment (speak to your accountant).
What's the payback on commercial solar?
Because businesses typically use most of their power during daylight hours, payback can be faster than residential — but it depends on your usage, tariff, system size and real-world output. We provide a tailored estimate, with assumptions stated, as part of your quote. Actual results vary.
Can my business claim the federal incentive?
Systems up to 100kW can be eligible for small-scale technology certificates (STCs), applied as an upfront discount; larger systems fall under a different mechanism (large-scale generation certificates). Eligibility criteria apply — we'll explain what applies to your project.
Will installation disrupt our operations?
We schedule around your business hours wherever possible and plan the installation to minimise disruption. We'll agree the approach with you before we start.
Does my business need three-phase power?
Most commercial systems use three-phase power. We confirm your connection type and your network's export rules as part of the design.
What size system does my business need?
It depends on your load profile and available roof or ground space. We assess your energy use and design a system sized to what genuinely benefits your business.
