Is Solar Worth It in Tasmania in 2026? An Honest Guide

Tasmania is not the rest of Australia when it comes to solar. It gets less sun than the mainland, its electricity demand peaks in winter (when panels produce least) rather than in summer, and its feed-in tariff is a regulated minimum rather than whatever a retailer feels like paying. All of that changes the answer to "is it worth it?" — and for some households the honest answer is "only just". This guide walks through the numbers that actually matter as at September 2026.

What Tasmanian panels really generate

A rooftop system in Tasmania yields roughly 1,150 kWh per kW of panels per year — noticeably lower than the mainland benchmark of around 1,400 kWh/kW. A well-sited 6.6 kW system therefore produces in the ballpark of 7,600 kWh across a year. That's still a lot of energy, but the seasonal shape is the catch.

Tasmanian generation is heavily front-loaded into summer. In the depths of winter — short days, low sun angle, more cloud — output can fall to a fraction of the summer peak. This matters more here than anywhere else because Tasmania is winter-peaking: your biggest bills come from heating in the exact months your panels are quietest. Solar shaves your summer bills hard and your winter bills much less.

The regulated feed-in tariff — and why self-consumption wins

Unlike most states where retailers set (and keep cutting) the feed-in tariff, Tasmania has a regulated minimum set by OTTER. As at September 2026 that minimum is 9.276 cents per kWh, in effect since 1 July 2026. Some plans sit a touch higher, in the 8–10 c/kWh range. Always confirm the current financial-year rate and your actual plan.

Here's the thing: 9.276c is far less than what you pay to buy a unit of grid power. Every kilowatt-hour you use as it's generated is worth the full retail rate you'd otherwise pay — often three to four times the feed-in value. So the entire economics of Tasmanian solar hinge on self-consumption, not export.

Aurora's Time-of-Use plan (Tariff 93) reinforces this: winter peak periods are Mon–Fri 7–10am and 4–9pm; summer peak is Mon–Fri 8–11am and 5–10pm, with weekends off-peak. Your solar generation lands mostly in the middle of the day — largely outside those peak windows — which is another reason exporting or shifting your usage matters. Check your own bill to confirm which tariff you're on.

What a system costs, and rough payback

Indicative installed prices in Tasmania, after the federal STC discount is already applied:

System size	Typical installed price (after STC)
6.6 kW	$5,500 – $9,000
10 kW	$8,000 – $12,000
13.2 kW	$7,500 – $13,000

Those prices already include the federal Small-scale Renewable Energy Scheme (STC) benefit. Single-phase homes in Tasmania can generally export up to 10 kW — more generous than the 5 kW limit common elsewhere — though your installer should confirm what TasNetworks allows at your address.

Payback depends almost entirely on how much of your generation you use yourself. A household that's home during the day, with electric heating and hot water it can shift to daytime, can do well. A household out all day that exports most of its solar at 9c will wait much longer. There is no Tasmanian state solar rebate and no state certificate scheme (TAS has no equivalent of the NSW or Victorian schemes) — the only subsidy is the federal STC already in the prices above.

Here's the catch — where solar might NOT pay in Tasmania

We say this plainly because we sell nothing: solar is a weaker fit in Tasmania than in, say, Queensland, and for some homes it may not clear the bar.

• You're out all day with no way to shift load. If most of your generation exports at ~9c while you buy peak power back at full rate in winter evenings, the gap eats your savings.
• Your bills are already low. Small usage means small savings, which stretches payback well past the point where it's compelling.
• Heavy winter heating, low summer use. This is the classic Tasmanian mismatch — panels are quietest exactly when your demand is highest.
• The Solar Sharer free-power window does NOT apply in Tasmania in 2026. A 2027 extension is being consulted on (verify), but a midday free window is worth less here anyway given the winter-peaking profile.

A battery can improve self-consumption, and the federal Cheaper Home Batteries program applies in Tasmania (an STC-based discount, indicatively around $250–$300 per usable kWh, floating with the certificate price — verify at quote). But a battery adds thousands to the outlay, and typical battery payback sits around eight years. It's a separate decision that should be modelled on your own usage, not bundled in as a default.

How to know if it's worth it for you

The single most useful number isn't the panel price — it's your daytime self-consumption. Pull twelve months of interval data from your bill, look at how much power you actually use while the sun is up, and model the split between self-consumed value (full retail) and exported value (9.276c). That's the honest calculation, and it's specific to your household.

We don't sell panels, batteries or installs, and we never will. That's the whole point: our only job is to tell you whether solar pays for your Tasmanian home — including when the honest answer is that it doesn't.
