Key Findings
Solar payback under 4 years in South Australia
SA has Australia's highest electricity prices (38c/kWh), making solar savings the most dramatic. Combined with strong sun hours, SA offers the fastest payback period in the country.
WA feed-in tariff at just 2.25c/kWh changes the equation
Western Australia's ultra-low feed-in tariff means self-consumption is critical. WA homeowners should pair solar with a battery or shift heavy usage (EV charging, heat pump) to daytime hours.
Victoria rebate stacking saves up to $5,200
Victorian homeowners can stack federal STCs ($2,500-$3,500) with the Solar Victoria rebate ($1,400) for the largest total discount. Combined with competitive metro installer pricing, VIC offers excellent value.
Methodology
The PumpSwap Solar Cost Index is compiled from installer quote data, manufacturer pricing, STC values, and state rebate programs across 1,534 Australian suburbs. Prices reflect 6.6kW systems fully installed including panels, inverter, mounting, and all labour.
