Two things worth knowing before you dive in. First, the federal solar and battery rebates apply everywhere, so even if your state offers nothing extra you’re still getting the national discounts — each guide below spells out how they apply locally. Second, state schemes change far more often than the federal ones; they open, shrink and close with budgets and election cycles, so treat the figures here as a starting point and confirm the current detail for your postcode before you budget around it.
New South Wales
NSW has just become one of the better-supported states: a brand-new Home Energy Saver zero-interest loan of up to $15,000 (open since June 2026) sits alongside the Peak Demand Reduction Scheme’s incentive for connecting a battery to a virtual power plant. There’s no upfront state rebate on the battery hardware itself — that’s the federal rebate’s job — but the loan and the VPP payment both stack on top of it.
Victoria
Victoria keeps a $1,400 rebate on solar panels, plus a matching interest-free loan, for eligible owner-occupiers — though the income cap tightens from 1 July 2026. Batteries are covered by the federal rebate rather than a state one. If you’re close to eligible, the 30 June 2026 cut-off for the higher income threshold is the date to watch.
Queensland
Queensland leans on the federal rebates, and because it sits in a sunnier STC zone the solar discount is a little larger per panel than down south. The main state-specific offer is Supercharged Solar for Renters — up to $3,500 for landlords putting solar on a rental.
South Australia
South Australia’s headline state offer is the REPS incentive — a cashback, commonly up to around $2,000, for connecting a battery to an approved virtual power plant on top of the federal battery rebate. Residents inside the City of Adelaide council area can also tap a separate council scheme.
Western Australia
WA is one of the best states for batteries: the WA Residential Battery Scheme adds $1,300 (Perth/Synergy) or $3,800 (regional/Horizon) on top of the federal rebate, plus a no-interest loan of up to $10,000 for eligible households. The catch is that you have to join a virtual power plant to get the rebate.
Tasmania
Tasmania doesn’t currently run a state solar or battery rebate, so the two federal rebates are your main support. The state does set a regulated minimum feed-in tariff, which is higher than what most mainland retailers offer.
Australian Capital Territory
The ACT’s Sustainable Household Scheme offers a low-interest (3%) loan of up to $15,000 — rising to $20,000 from July 2026 — covering batteries and most home-electrification upgrades. Concession-card holders can also get solar and upgrade rebates through the Home Energy Support program, all on top of the federal rebates.
Northern Territory
The NT’s Home and Business Battery Scheme has offered a grant of $400 per kWh (up to $12,000) toward a battery — but it’s been heavily subscribed, so check whether it’s still open before relying on it. Either way the federal rebates apply, and the NT’s high-sun zone makes the solar discount especially generous.
