Complete Guide to Australian Solar Rebates & Incentives 2025

Installing solar in Australia in 2025? You could save between $2,000-$7,000+ through various government rebates and incentives. This comprehensive guide breaks down every rebate available to help you maximize your savings.

Federal Solar Rebate (STCs)

The main federal incentive is the Small-scale Renewable Energy Scheme (SRES), which provides upfront discounts through Small-scale Technology Certificates (STCs).

2025 STC Values

Worth: Approximately $300 per kW installed
6.6kW System: $2,000-$2,600 discount depending on location
STC Price: Currently $38-$39 per certificate
Important: Rebate value decreases annually, ending December 31, 2030

How STCs Work by Zone

Australia is divided into 4 zones based on solar irradiance:

Zone	Example Cities	6.6kW Rebate
Zone 1	Darwin, Cairns	$2,304
Zone 2	Brisbane, Perth	$2,160
Zone 3	Sydney, Adelaide	$1,944
Zone 4	Melbourne, Hobart	$1,656

Pro Tip: Your installer typically handles the STC paperwork and applies the discount upfront. Always use a Clean Energy Council (CEC) accredited installer.
