Commercial electricians work on higher-load systems — three-phase power, switchboard and distribution boards, emergency and exit lighting, commercial solar, and the kind of wiring found in warehouses, offices, retail spaces, and industrial sites. The scope, compliance requirements, and system complexity are all different from a standard home. At DJ Edwards, we handle both, but our commercial work spans Brisbane, Gold Coast, Sunshine Coast, and Toowoomba.
Yes. All electrical work on commercial properties in Queensland must be carried out by a licensed electrical contractor. This includes new fit-outs, switchboard upgrades, energy efficiency upgrades, and any solar installation. Unlicensed electrical work is illegal, voids your insurance, and creates serious liability if something goes wrong. Always ask for a contractor licence number before signing anything.
For most Queensland businesses, yes. A commercial solar system can cut electricity costs by 50 to 70 percent, and with Queensland's high solar hours, payback periods of 3 to 6 years are common. After that, the savings go straight back into the business. With energy costs rising year on year, solar is increasingly one of the best capital investments a business can make.
Cost depends on system size, roof type, and whether you add battery storage. A small commercial system (around 30kW) typically starts from $25,000 to $40,000 before incentives. Larger systems cost more, but the per-kilowatt price drops as size increases. The best starting point is getting a quote based on 12 months of your actual energy bills — that's what we base our sizing on.
There's no universal answer — it depends on how much power your business uses during the day and how much usable roof space you have. A good installer will analyse your interval meter data and match system size to your daytime consumption. Oversizing sounds good but doesn't always maximise ROI; undersizing leaves savings on the table. Book a commercial solar assessment and we'll size it properly.
Most Queensland businesses see payback in 3 to 6 years, depending on system size, energy use, and feed-in tariff rates. Businesses with high daytime energy use — retail, manufacturing, hospitality, healthcare — typically see the fastest returns because they're consuming solar directly rather than exporting it. A well-designed system will keep delivering savings for 25 years or more.
It's possible, but it requires landlord approval and a clear agreement about ownership, removal, and what happens at lease end. Some landlords are open to it — particularly if you present the case as adding value to the building. Power Purchase Agreements (PPAs) are another option, where a third party owns and maintains the system and you pay for the electricity it generates at a reduced rate.
