What a solar system size costs in Hobart
Hobart gets the fewest peak-sun hours of the capitals, and short, overcast winters cut generation exactly when the city's electric and hydronic heating runs hardest, so a system that performs in summer only lightly offsets peak winter demand, and getting the size right matters more here than in a sunnier city. Colonial and early-twentieth-century homes on sloping or shaded sites can also limit the usable north-facing area, so a careful roof assessment comes first.
The sizing call leans on usage: a daytime-heavy household captures more of the summer yield, while a home wanting to offset winter evening heating needs a larger array paired with a battery to be worthwhile. Tasmania's power prices support the investment, but a smaller installer market and some Bass Strait freight lift the install cost, so a Hobart system is sized against a genuinely modest solar resource rather than the generous one further north.

Frequently asked questions
What size solar system do I need?
It depends on your consumption. As a guide, a ~$500 quarterly bill suits a 6.6kW system; a $1,000+ bill may need 13kW. The calculator estimates this from your bill.
How much does solar cost in Australia?
About $900–$1,300 per kW installed after rebate in 2026, roughly $5,000–$8,000 for 6.6kW and $9,000–$13,000 for 10kW.
Is a solar battery worth it?
Batteries increase self-sufficiency and backup but roughly double the project cost. Payback depends on your usage pattern and any battery rebates.
