Solar Battery Comparison: Which One Is Right for You?

Powering your home when the sun goes down requires more than just solar panels. The right battery system lets you store sunshine for later, cut bills and keep the lights on during outages. This guide compares popular solar batteries available in 2025, explains different battery chemistries, outlines government rebates and helps Australian households decide which storage solution is best for them.

Why consider a solar battery in Australia?

Australia’s love affair with rooftop solar continues. By mid‑2025, more than 3.5 million homes had solar panels and many households were exploring batteries. Several factors make 2025 a particularly attractive time:

• Rising electricity prices and shrinking feed‑in tariffs: Day‑time export rates have fallen below $0.05 per kWh in some states, reducing the return from sending solar back to the grid. Using a battery to self‑consume solar generation protects households from higher retail tariffs.
• Cheaper Home Batteries Program: The federal government’s new program, introduced on 1 July 2025, provides a discount of about 30 % on the upfront cost of eligible batteries by awarding additional Small‑scale Technology Certificates (STCs). Only batteries between 5 and 100 kWh, installed by accredited installers and listed on the Clean Energy Council’s approved product list, qualify.
• State incentives: NSW’s Peak Demand Reduction Scheme offered $1,600‑$2,400 off battery installations and an extra $250‑$400 for connecting to a Virtual Power Plant (VPP). Although this rebate is suspended after 30 June 2025, the federal program now covers the incentive and NSW residents can still claim a new VPP payment that scales with battery size—for example, roughly $550 for a 10 kWh battery and $1,500 for a 27 kWh system.
• Blackout protection: Extreme weather events have highlighted the fragility of grid infrastructure. A battery with blackout capability can supply critical loads during outages, providing peace of mind.
• Virtual power plants (VPPs): Joining a VPP lets you share stored energy with the grid during peak demand in exchange for credits. NSW’s new VPP incentive, available from July 2025, can be combined with the federal rebate. Participating providers include AGL, Amber, Engie, GloBird, Origin, Powow and ShineHub.
