Where the money goes
Estimated breakdown for your configuration
Size your system to your usage, not just your roof. After rebates (STCs), a 6.6kW system is the most common Australian choice and usually pays for itself in a few years.
Ways to save
- Size to your actual bill, an oversized system that exports cheaply pays back more slowly.
- Federal STC rebates cut the upfront cost significantly, built into most quoted prices.
How we estimate this
Most Australian homes need a 6.6kW to 10kW solar system in 2026, costing roughly $4,000 to $15,000 installed after STC rebates, depending on size and components. Your power bill is the best guide to the right size.

What a what size solar system do i need costs in Hobart
Choosing a solar size in Hobart is a matter of the panel array in kilowatts, separate from battery storage: the array is sized to the home's daily electricity consumption and the daylight share, because power generated during the day offsets a daytime bill. A home running heating hard in the cold evening draws most after dark, so without a battery the daytime use is what the array most directly offsets, which shapes the sizing. The small Tasmanian market with limited competition keeps the install firm, and specialist components can carry island freight.
Hobart's high latitude gives it the shortest winter daylight and the lowest winter sun angle in the country, so an array generates much less through the depths of winter than in summer, and sizing only to summer leaves a winter shortfall, which argues for a slightly larger array to lift the winter yield. The long summer days, by contrast, generate strongly. The roof caps the array, as panels need unshaded north, east or west faces, and a colonial or weatherboard home's roof or a sloping-site roof hosts what it can. The cold-evening heating load makes a battery attractive, arguing for a bigger array to charge it, so headroom is common.
A solar install is licensed electrical work done by a licensed electrician who is also an accredited solar installer in Tasmania under the state regulator, and the grid connection is arranged with the network. For a Hobart home, the clearest way to size a solar system is by the daily consumption and the daytime share, with the short winter daylight the main limit and the small market keeping the rate firm.

Frequently asked questions
How is solar system size worked out in Hobart?
As a panel array in kilowatts sized to the home's daily consumption and the daylight share, so without a battery the daytime use is what a Hobart array most directly offsets, since a home running heating hard in the cold evening draws most after dark.
Does the short winter daylight limit solar in Hobart?
Yes. Hobart's high latitude gives the shortest winter daylight and lowest winter sun angle in the country, so an array generates much less through winter, which argues for a slightly larger array to lift the winter yield.
Is a solar install dearer in Hobart?
Firm, rather than cheap. The small Tasmanian market with limited competition keeps the install firm, and specialist components can carry island freight, adding to a Hobart install compared with the mainland.
Do I need an accredited installer in Hobart?
Yes. A solar install is licensed electrical work done by a licensed electrician who is also an accredited solar installer in Tasmania under the state regulator, with the grid connection arranged with the network.
