Commercial solar in Wollongong

The Illawarra coast enjoys reliable sunshine, and with rising grid prices, Wollongong is well placed to benefit from solar and battery storage. We install throughout the region.

Every Wollongong install starts on the roof itself. We assess pitch, orientation and anything casting shade, then design around how your household actually uses power rather than a standard package. Tier 1 panels, CEC-accredited installers, and a system sized to the home it sits on. What it generates will always come down to your roof, shading and usage.

Why Wollongong businesses go solar

  • Homes tucked under the Illawarra escarpment can lose late-day sun, so panel placement and string layout matter here more than in flatter parts of NSW.
  • Between Bulli and Shellharbour the salt air is unrelenting, so mounting hardware and racking need to be specified for a coastal site, not an inland one.
  • West Dapto's new estates and the older brick-and-tile suburbs around Figtree call for different approaches, and Endeavour Energy's export rules shape how each system is set up.

Commercial systems up to 100kW can be eligible for small-scale technology certificates (STCs), applied as an upfront discount; larger systems use large-scale generation certificates (LGCs). Eligibility criteria apply. EFS Solar is not affiliated with any government body. See our solar & battery rebates guide for the current detail.

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.
