Solar power in St Helens, explained plainly.

Tasmania’s sunniest coast

St Helens is the largest town on Tasmania’s east coast, on Georges Bay beside the Bay of Fires. It’s the same STC Zone 4 as the rest of the state for rebate purposes — but it has a genuine generation edge:

• The sunniest region in Tasmania. The east coast records the state’s highest sunshine hours, so a well-oriented system here generates at the top of the Tasmanian range.
• Cool climate, efficient panels. All that sun, plus Tasmania’s mild temperatures, is an ideal combination — panels run efficiently and the light is plentiful.
• Holiday homes and shacks. Many properties are used part of the year, which makes a system with a battery — and strong self-consumption — especially attractive.

A 13kW system on a well-oriented St Helens roof generates in the order of 15,500 kWh a year — among the best in the state. See the full output and payback maths →

System size, rebates and the feed-in tariff

TasNetworks allows a 10kW inverter on a single phase, so most St Helens homes can fit around a 13kW system (≈13.3kW of panels) — well past the old 6.6kW default. The federal STC discount takes about $3,400–$3,900 off a 13kW system in 2026, plus the federal Cheaper Home Batteries Program for storage. With the Aurora feed-in tariff at just 8.782 c/kWh, design around using your own power and choose the right electricity plan.

Local quirk: many older Tasmanian homes are two-phase, and your solar usually sits on one phase — so it pays to put it on the phase carrying your daytime load. More on phases →
