How we estimate this
Solar in Australia in 2026 typically costs $900–$1,300 per kW installed after the federal rebate, so a 6.6kW system runs roughly $5,000–$8,000 and a 10kW system $9,000–$13,000.

What a solar system size costs in Canberra
Canberra's clear, cold winter days actually generate efficiently, since panels perform better in cool air, and the hot dry summers deliver strong output, so the solar resource supports a good-sized system on the territory's typically clear roofs. The large ex-government and newer stock usually offers workable north-facing area, so the roof rarely caps the array.
Sizing is dominated by the severe winters: Canberra households run hard on reverse-cycle and hydronic heating when winter days are shortest, so a system that generates best in summer only partly offsets peak winter demand, and many homes size larger, or add a battery, to carry that load rather than buy expensive winter grid power. The cooling-light, heating-heavy pattern is the key difference from the northern capitals when deciding how big to go.

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.
