Solar & battery rebates in Tasmania

1. The federal STC discount (the big one)

The main upfront help for rooftop solar is the federal Small-scale Technology Certificate (STC) scheme. It isn’t a cash rebate — it’s a point-of-sale discount your installer applies, then claims back. You don’t fill in any forms.

• Tasmania is STC Zone 4 — the lowest-rated zone, because we get less solar irradiance than the mainland. An identical system therefore earns fewer certificates here.
• The number of certificates depends on system size, the zone rating, and the “deeming period” (years left until the scheme ends in 2030). For a 2026 install the deeming period is 5 years.
• Each certificate is worth roughly $38–$39 at typical market prices.

In practice, the 13kW system we usually recommend (≈13.3kW of panels on a 10kW inverter) attracts about $3,400–$3,900 off the price in 2026 — while a smaller 6.6kW system gets about $1,700–$2,000. The bigger system earns the bigger rebate, and in Tasmania it still fits on a single-phase connection.

Heads-up: the STC discount shrinks every 1 January as the deeming period shortens, and the scheme ends in 2030. Sooner is worth more. Always check the STC line is itemised on your quote.

2. Batteries: the Cheaper Home Batteries Program

Adding storage? The federal Cheaper Home Batteries Program is the main incentive for Tasmanians in 2026. It gives an upfront discount on an eligible battery installed with solar — broadly around 30% of the battery’s cost (roughly $2,500–$3,700 off a 10kWh unit).

• The discount is tiered by battery capacity and steps down over time (the structure was adjusted from 1 May 2026), so the dollar figure depends on when and what you install.
• Like the STC discount, it’s applied by your installer at the point of sale.

3. The Tasmanian Energy Saver Loan Scheme — now closed

You may still see the state’s interest-free Energy Saver Loan Scheme mentioned online. It has closed — applications ceased on 1 September 2025 after the funding was exhausted. As of 2026 there is no active Tasmanian state-level rebate or loan for solar or batteries; the support on offer is federal (STCs and the battery program).

What this means for you

The rebates are real and worth claiming, but they’re shrinking — and a good installer applies them automatically and shows them on the quote. The bigger lever for most Tasmanian homes isn’t the rebate at all; it’s sizing the system so you use as much of your own solar as possible, because that’s worth far more than the feed-in tariff.
