Is solar worth it in Tasmania in 2026? Yes, with the right sizing
A 6.6kW system in Tasmania costs $6,100–$8,900 installed after the $1,558 federal STC discount, generates about 6,764 kWh a year from 3.6 peak sun hours, and saves $1,070–$1,490 a year at 30c/kWh with a 9.28c feed-in tariff. That is a simple payback of 5.0–7.0 yrs on panels warranted for 25 years — roughly $21,300 net benefit over the panels' life at today's prices, before any electricity price rises.
The Tasmania question. Tasmania has the lowest sun hours in the country, so a 6.6kW system makes about a third less electricity than the same roof in Brisbane. Three things still make the maths work: the feed-in tariff is the highest in Australia at 9.28c/kWh (Aurora's regulated rate), so exported power is not wasted; electricity at 30c/kWh is dear enough that daytime self-use pays; and the Energy Saver Loan Scheme offers interest-free loans of $500–$10,000 over three years for solar, batteries and efficient heating, so most households can install with no upfront cash. Winter output is low (June produces about a third of January), which is why Tasmanian systems should be sized a little larger than the bill alone suggests and why heat-pump hot water on a timer is the best companion to solar here.
Tasmania has lower sun hours, but the Energy Saver Loan Scheme lets you finance solar and batteries interest-free, and Aurora's regulated 8.9c feed-in tariff is the best in the country — exported solar is worth more here than anywhere else.

Which size pays back fastest in Tasmania?
Bigger systems pay back faster in Tasmania because the fixed install cost is spread over more panels — as long as you use the extra power or have a decent feed-in rate.
| System | Installed after STCs | Yearly saving | Payback |
|---|---|---|---|
| 5kW | $5,000–$7,333 | $810–$1,130 | 4.9–6.9 yrs |
| 6.6kW | $6,111–$8,889 | $1,070–$1,490 | 4.5–6.3 yrs |
| 8kW | $7,111–$10,333 | $1,300–$1,800 | 4.4–6.0 yrs |
| 10kW | $8,889–$12,889 | $1,620–$2,250 | 4.4–6.0 yrs |
| 13kW | $11,111–$16,111 | $2,110–$2,930 | 4.2–5.8 yrs |
Is a battery worth it in Tasmania?
A 10kWh battery costs $6,984–$9,984 after the federal discount and saves about $605 a year in Tasmania by moving daytime solar to the evening — a payback of 11.5–19.4 years against a 10-year warranty. With Tasmania’s 9.28c feed-in rate the gap between export and self-use is the narrowest in the country, so a battery here is about blackout protection and VPP income more than bill savings.

When solar is not worth it in Tasmania
- Heavy shading from trees or buildings for more than a couple of hours a day — optimisers help, but a 40% shaded roof rarely pays
- Moving within 3 years — solar adds resale value, but usually less than it cost
- Nobody home in daylight and no battery — export-only systems at 9.3c barely cover the inverter
- A quarterly bill under $250 — a 5kW system still makes sense on most roofs, but a 10kW one does not
- Renting without landlord approval — see solar for renters for what does work
Tasmania solar questions
Is solar worth it in Tasmania in 2026?
Yes, with the right sizing. A 6.6kW system costs $6,100–$8,900 after rebates, saves $1,070–$1,490 a year and pays back in 5.0–7.0 yrs, then keeps producing for 15–20 more years.
What is the solar payback period in Tasmania?
About 5.0–7.0 yrs for a 6.6kW system; faster for 10kW+ and for homes that use most of their power in daylight.
How much does solar save per year in Tasmania?
$1,070–$1,490 for 6.6kW at 30c/kWh, assuming about 40% self-use and 9.3c for exports. A 10kW system saves $1,620–$2,250.
What rebates are there in Tasmania?
The federal STC discount ($1,558 on 6.6kW in Zone 4), the federal battery discount ($252/kWh) and the Energy Saver Loan Scheme (interest-free up to $10,000). Details on the TAS rebates page.
