Tablelands Off-Grid Guide · SAA S0111813
Off-Grid Solar on the Atherton Tablelands
Real system designs, costs and wet-season lessons from Shorecan Electrical & Solar — based in Ravenshoe and installing off-grid systems across the Tablelands since 2013.
Investment Ranges (Installed, After Federal Battery Rebate)
Gas cooking/HWS, modest loads, weekender or small lifestyle block.
Aircon, electric HWS, full residential standard with backup genset.
Bores, sheds, workshops, multiple buildings or commercial loads.
A Real Tablelands Off-Grid Design
For a typical 3-bedroom Ravenshoe / Kaban / Herberton home running aircon, electric hot water and a couple of fridges:
Why people go off-grid up here
No grid available
Plenty of properties around Kaban, Mt Garnet, Innot Hot Springs, Millaa Millaa and out west toward Mt Surprise simply can't get an Ergon connection.
Grid connection cost-out
Once Ergon quotes more than ~$40,000 for a connection, off-grid almost always wins on whole-of-life cost.
Reliability
Tablelands grid feeders run long distances through bush — single-tree-down outages of 6–24 hours are normal in storm season.
Independence
Lifestyle blocks, retirement, agricultural and tourism properties opting out of rising network charges entirely.
The Wet-Season Rule
Anyone can size a system for the dry. The Tablelands gets stretches in Jan–Mar where the array produces 20–30% of nameplate for 5–7 days running. Two design rules we hold to:
- •Oversize the array by ~30% vs the grid-tied size you'd otherwise pick. Cheap panels make this easy.
- •Always wire in a generator. A 5 kVA diesel auto-start, run 30–60 hours a year, beats spending another $15,000 on battery.
Why Deye for off-grid
Most "hybrid" inverters quietly void warranty the moment they spend extended time off-grid. The Deye hybrid we install is one of the only options on the Australian market with a full 10-year warranty even in continuous off-grid operation. For a $60,000 system that's not optional — it's the whole point.
