Solar Panel Cost in NSW (2026)
Model NSW solar ROI with local electricity rates, installed costs, and incentives.
Last updated: 2026-06-25· Source label: EIA residential electricity rates, IRS federal clean energy credit, NREL/PVWatts solar assumptions
New South Wales has excellent solar conditions with 4.5 peak sun hours/day and installed costs around AU$1.00/W (Solar Choice Price Index June 2026). A standard 6.6 kW system costs approximately AU$6,600 installed. STC certificates provide ~AU$2,700 upfront discount. Electricity rates average 30c/kWh. Feed-in tariffs for exports pay ~5-8c/kWh. Payback is typically 4-5 years, making NSW one of the best solar markets globally.
