Model Northern Territory solar ROI with local electricity rates, STC rebates, and the NT Home and Business Battery Scheme.
Last updated: 2026-06-25· Source label: EIA residential electricity rates, IRS federal clean energy credit, NREL/PVWatts solar assumptions
The Northern Territory (Darwin) boasts the highest peak sun hours in Australia at 5.8 hours per day. Installed solar costs are around A$1.00/W (Solar Choice Price Index June 2026). A standard 6.6 kW system costs approximately A$6,600 installed. STC certificates provide ~A$2,700 upfront discount. Electricity rates average 27c/kWh. The NT Home and Business Battery Scheme offers up to A$6,000 grant for battery storage. Payback is typically 4 years, and the high sun hours make the NT ideal for solar generation.
