As energy prices continue to rise, many Sydney homeowners are turning to solar battery systems to store excess solar power and slash electricity bills. With the recent announcement of the Labor Government’s Cheaper Home Batteries Program, solar battery installation in Sydney has become more affordable than ever. This 2025 price guide explains what you can expect to pay for a solar battery system, how the government rebate works, and how to get started.
What Is the Cheaper Battery Program?
The Labor Government’s Cheaper Home Batteries Program is a $2.3 billion initiative aimed at subsidising over one million new battery installations across Australia by 2030. Under the scheme, eligible households and businesses can receive approximately $370 per kWh of usable battery capacity, resulting in an average 30% reduction in solar battery cost—that’s about $4,000 in savings for many installations.
Solar Battery Installation Cost in Sydney (Before and After Rebate)
In 2025, the typical solar battery installation cost in Sydney ranges between $8,000 and $15,000, depending on the battery size (usually 5 kWh to 13 kWh), brand, and installation complexity. For example:
- 5 kWh battery system: ~$8,000 (Before rebate)
- 10 kWh battery system: ~$12,000–$13,000 (Before rebate)
- 13 kWh battery system: ~$15,000+ (Before rebate)
With the government rebate, Sydney homeowners could save approximately $3,000–$5,000 depending on battery size and configuration. This brings the net solar battery cost down to as low as $6,000 for a 10 kWh system—making battery storage far more accessible than before.
Other Financial Benefits
In addition to the upfront rebate, solar batteries enable households to reduce grid electricity use during peak times, participate in Virtual Power Plants (VPPs), and gain energy independence. Over time, the cost savings on energy bills can significantly offset the initial investment.
Eligibility and Installation Requirements
To qualify for the rebate, your home must already have a solar panel system installed. The battery must be:
- Between 5 kWh and 50 kWh
- VPP-ready, though VPP participation isn’t mandatory
- On the Clean Energy Council’s approved list
Installations must not be commissioned (i.e., switched on) before 1 July 2025, as the rebate applies only to new systems post that date.
