The 2026 Australian Solar Panel Buying Guide
Why 2026 is a great year to go solar
Solar payback periods in Australia are now commonly 4–6 years thanks to higher grid electricity prices and a maturing installer market. A well-specified 6.6kW or 10kW system can cover most of a typical household's daytime usage.
How to size your system
A rough rule of thumb is 1kW of solar per 4kWh of daily usage. Check your last four power bills for daily average kWh and aim slightly above that figure so you can cover an EV or future battery.
