Commercial solar for Willawong businesses
Cut daytime operating costs with a commercial system designed around your load profile, delivered on time and on budget.
Why Willawong homes choose RS Energy for commercial solar
Businesses use most of their power during the day, which is exactly when solar produces. That makes commercial solar one of the fastest paybacks in energy, often 3 to 5 years. RS Energy has delivered large-scale installs across Queensland for tier one clients, and we give Willawong businesses the same standard with a family company's attention.
We start with your interval data or bills, model your load profile, then design a system that maximises self-consumption within Energex connection rules. Since 1 October 2026 the upfront small-scale rebate (STCs) covers commercial systems up to 1MW, where it used to stop at 100kW. For mid-sized systems that can take a meaningful chunk off the upfront cost, and we will show you exactly what your business qualifies for.
Brisbane's southside covers older post-war suburbs like Annerley, Moorooka and Holland Park, the busy family areas around Sunnybank, Mansfield and Carindale, and newer pockets at Pallara and Forest Lake. Our commercial solar work in Willawong also covers neighbouring Pallara, Doolandella and Durack, all within about 2km.

Willawong: a local snapshot
Oxley Creek and Blunder Creek trace most of the boundary, and the Sydney to Brisbane rail corridor runs down the east side. Only around 145 people live here. Land is taken up by a council resource recovery centre and the city's largest bus depot, holding over 200 buses on Sherbrooke Road, plus part of the 150 hectare Archerfield Wetlands. The CBD is about 17 km north by road.

Commercial solar in Willawong: questions
Still unsure? Talk to us directly. You will speak with the people who do the work.
Call 0449 942 735How quickly does commercial solar pay back?
Businesses that operate during daylight hours typically see payback in 3 to 5 years, because almost all the solar is used on site at your full tariff rather than exported.
What size system does my business need?
It depends on your daytime load. We use your interval data or 12 months of bills to model usage and size the system so very little goes to waste.
Is there a rebate for commercial solar?
Yes. From 1 October 2026 the federal small-scale rebate (STCs) applies to systems up to 1MW, up from the old 100kW limit, with a fixed five-year deeming period. Larger systems can still use the large-scale scheme instead. We include the rebate in your quote.
Who have you installed for?
Projects include a 100kW system for Aldi Hervey Bay, 100kW for James Hardie Cooroy, 64kW for BP Gatton, 60kW for Telstra, 100kW for Metal Works Brisbane and 70kW for Bellissimo Coffee in Coorparoo.
