Running a motel or accommodation property in rural Queensland isn't cheap. Air conditioning running around the clock, hot water systems, pool pumps, common area lighting, commercial laundry, the power bills are relentless, and they've only been heading one direction over the past decade.
Commercial solar is one of the most reliable tools available to hospitality businesses right now to get those costs under control. Here's what you need to know.
The Business Case for Motel Solar in 2025
Commercial businesses in Queensland are typically paying 28–35 cents per kilowatt-hour for daytime electricity from the grid. A well-designed solar system offsets this directly every kilowatt-hour you generate yourself is a kilowatt-hour you're not buying.
According to Solar Choice modeling across nearly 400 Australian business cases, commercial solar installations typically achieve payback within three to six years. After that, you're generating free electricity for the remaining 15–20+ years of the system's life. For motel operations which run high loads during daylight hours the economics are particularly strong.
What Kind of System Does a Motel Need?
Most regional Queensland motels would suit systems in the 20–100kW range, depending on the number of rooms, amenities, and operating hours. A well-sized system covers your daytime consumption when air conditioning, laundry, and common area systems are running hardest.
For a typical 20-room motel, a 30–50kW system is often a good starting point. Larger properties with pools, restaurants, or function areas may need 75–100kW. We size everything based on your actual bills, not guesswork.
What About After Hours?
If your motel has significant overnight power draw which most do there are two options worth discussing. A battery storage system can carry stored solar energy into the evening, reducing grid purchases during expensive peak periods. Alternatively, a well-sized system without a battery still delivers significant daytime savings while overnight draw is covered by the grid at standard rates.
The right answer depends on your specific load profile. We analyze your bills before recommending anything.
What's the ROI Timeline?
Based on Solar Choice data and Queensland commercial electricity rates, a 3–6 year payback is achievable for most motels with high daytime usage. At the lower end are properties with constant air conditioning loads and three-phase power. After payback, the ongoing savings go straight to your bottom line typically $10,000–$40,000 per year depending on system size and your current power costs.
The STC Rebate Applies to Commercial Installations
The federal government's Small-scale Technology Certificate (STC) scheme applies to commercial systems up to 100kW capacity, providing a significant upfront cost reduction applied directly as a point-of-sale discount. Systems over 100kW access incentives via Large-scale Generation Certificates (LGCs).
$0 upfront finance options are available through our Plenti partnership, meaning you can start reducing bills from day one without large capital outlay.
Warranty and Long-Term Support
We install Trina Solar panels with 25-year product warranties, Sungrow inverters with 10-year warranties, and back our own workmanship with a 5-year warranty. For a commercial operator, that warranty stack matters you need to know the system will perform and that there's local support if something goes wrong.
