More than 53% of homes in South Australia Solar Rebates currently have solar panels, making it the state with the most solar adoption in the country. The shift is even more inexpensive thanks to substantial rebate programs. If you’re thinking about getting your first solar panels in South Australia or updating to include battery storage, the mix of federal subsidies and state-specific programs can help you save a lot of money up front.
The Federal Solar Rebate Scheme: The Key to Savings
The federal Small-scale Renewable Energy Scheme (SRES) is the main part of South Australia’s solar rebate schemes. It helps people save a lot of money by giving them Small-scale Technology Certificates (STCs). This rebate lowers the cost of installing solar panels by about 25% to 30% in all of South Australia.
The federal incentive alone can save homes in Adelaide from $2,000 to $2,160 on a standard 6.6kW solar installation. The amount of the rebate depends on the size of your system, where it is, and how many years are left until the program finishes in 2030. At the moment, each STC is worth about $38-$39, thus it’s important to install them as soon as possible because the rebate goes down every year.
Requirements for eligibility:
- Solar systems with a capacity of less than 100 kW
- Installation by an installer who is certified by the Clean Energy Council
- Parts must be on lists that the CEC has approved.
- You have to make STCs within a year following installation.
The New Federal Battery Rebate Program
The Cheaper Home Batteries Program, which will start in July 2025, is the biggest change to incentives for storing energy in homes. This program from the federal government gives you up to $372 for every usable kWh of battery storage, which is almost $4,000 off the price of a normal 11.5–13.5kWh battery system.
Main Features:
Covers 30% of the cost of installing batteries
Works for the first 50 kWh of useful capacity
Available for batteries with a nominal capacity of 5 to 100 kWh
Must be used with new or existing solar systems
Batteries must be able to work with VPP, but you don’t have to join one.
Incentives from the State of South Australia
Retailer Energy Productivity Scheme (REPS) VPP Incentives South Australia gives you extra savings when you connect batteries to certified Virtual Power Plants under the REPS scheme. Depending on the size of the battery and the type of consumer, these cash rebates can be anywhere from $150 to $2,050.
Examples of REPS VPP Rebates:
- The price of the Tesla Powerwall 3 (13.5kWh) is between $670 and $880, depending on the priority category.
- LG RESU 10 (9.6kWh): $450 to $590
- Alpha-ESS SMILE (5.04kWh): $220 to $290
Customers in the priority group (such elderly and people with healthcare cards) get more rebates. You can use this program alongside federal rebates to get the most savings possible.
