Are Solar Panels Worth It in Tasmania?

Written by Jacob Ramilo, Last reviewed 2026. This guide provides general information only. See how we calculate the estimates.

Tasmania's solar picture is different from the mainland. Electricity prices, climate, and your household's usage patterns all affect the numbers. Solar can still reduce your bills, but payback may take longer than in sunnier states.

The Tasmanian Energy Context

For 2026–27, the regulated residential flat-rate tariff is 24.75c/kWh plus a 182c daily charge, while the regulated minimum FiT is 9.276c/kWh^[3]. The daily charge remains even when solar reduces grid imports, so payback should be base your payback on avoided usage and export credits. Solar does not remove the whole bill.

The upfront discount discussed in this article comes from the federal Small-scale Renewable Energy Scheme (STCs).^[1] Tasmania is in STC zone 4 (the lowest solar zone), so the federal discount is smaller than it would be for the same system in Brisbane or Darwin (see our methodology for the zone rating assumption).

Solar Performance in Tasmania's Climate

Tasmania's high latitude means short winter days but long summer days. A well-placed system can produce more power from October through March, when Tasmania has long summer days.

Winter is the challenge. Short days and more cloud cover mean significantly lower generation from May to August. Size your system so that winter generation reduces your daytime usage. Summer surplus can then be exported at the feed-in tariff.

One advantage: cool temperatures. Solar panels lose efficiency as they heat up. Tasmania's mild summer temperatures mean panels operate closer to their rated output than they would in a 40°C mainland heatwave.

Upfront Costs in Tasmania

The only upfront discount covered in this article is the federal STC. Typical pricing after the STC discount (prices are estimates based on our market research, see methodology):

• 6.6kW system: $4,500–$7,000
• 5kW system: $3,500–$5,500
• 8–10kW system: $7,000–$11,000

The installer market in Tasmania is smaller than on the mainland, which can mean less competition on price. Getting multiple quotes is worth the effort.

Payback Periods in Tasmania

Assume you buy a 6.6kW system for $5,000 after STCs. We estimate that it generates 5,000kWh a year. At the 2026–27 regulated flat import rate and minimum FiT, the estimate looks like this:

If you use 20% of the solar directly, the same example returns about $619 a year and simple payback rises to about 8.1 years. Generation and price are assumptions. The tariff and FiT apply to 2026–27. This example excludes supply charges, degradation and future rate changes.

The households that get the best results are those with high daytime usage, such as running appliances or working from home during the day. Every kWh you use directly from your panels saves the full retail rate.

If you're gone during the day and most solar gets exported, payback can stretch beyond 10 years. In that scenario, solar may still be worthwhile if you plan to stay long-term, but the economics are less compelling.

Connection Approval and Winter Design

TasNetworks requires approval before a new system connects and exports^[5]. Ask your installer to show the approved inverter capacity and export limit, not just the panel total. If you use more power in winter, compare monthly generation with your heating use. A yearly total can hide a large winter shortfall.

Is a Battery Worth It in Tasmania?

A battery's value depends on your import tariff, FiT, usable capacity, usage, efficiency and installed cost. The Cheaper Home Batteries Program provides an upfront discount through battery STCs. It does not guarantee a flat 30% discount. Your installation date and eligible usable capacity affect the support, and certificate values change^[4]. Compare solar on its own first. Treat backup power as a separate benefit.
