Key Findings
Victoria leads in installations due to the gas ban
With the 1 March 2027 deadline approaching, VIC has the most competitive pricing due to strong installer competition and the Solar Victoria rebate program.
Metro areas are 10-20% cheaper than regional
Higher installer density in metro areas creates price competition. Regional areas often face travel fees of $300-$600 on top of base installation costs.
Rebate stacking saves $1,500-$2,700 in VIC
Victorian homeowners can stack federal STCs ($500-$700) + Solar Victoria rebate ($1,000-$1,400) + VEU certificates ($300-$600) for the biggest total discount in the country.
