Do solar batteries pay for themselves in Australia?

Quick Answer
In 2026, usually yes. With the federal rebate cutting roughly 30% off hardware, feed-in tariffs near zero and evening rates of 30-45 c/kWh, a correctly sized battery pays back in 5-8 years against a 10-year warranty, faster with a VPP or wholesale tariff.
The payback case collapsed when feed-in tariffs fell: every kWh you store and use in the evening is now worth the full grid rate, not the difference between grid and export rates.
Sizing is everything. A battery that sits full by noon and empty by 8pm daily earns its keep; an oversized battery cycling at 40% depth is dead capital. Match usable kWh to your actual overnight consumption.
States stack further incentives (WA up to A$3,800, NT A$400/kWh) that can pull payback under five years.
