Will it cover your power use?
Average daily use for Australian homes, compared with what a 6.6 kW system makes in Bateman.
Across the year, a 6.6 kW system here makes more than a typical four-person home uses. In June it makes about 18 kWh a day, which is less than a four-person home uses.
Solar is made in the middle of the day, while most homes use more power in the morning and evening. Without a battery, a good share of what your panels make is exported to the grid, so solar covers less of your bill than these totals suggest. Running the dishwasher, washing machine and pool pump during the day helps.
Household use figures are Australia-wide averages from the Australian Energy Regulator's 2020 benchmarks. Air conditioning, a pool or an electric car can add a lot more.
Is Bateman good for solar?
Yes. Like the rest of Perth, Bateman is one of the sunniest places in Australia to own solar panels. It gets about the same sunshine as the Perth CBD, averaging 5.9 sun hours a day on a north-facing roof.
December is the strongest month, when a 6.6 kW system makes about 40 kWh a day. June is the weakest, at about 18 kWh, so expect your summer output to be roughly 2.2 times your winter output. That swing is normal and doesn't mean anything is wrong.
How many homes in Bateman have solar?
Solar systems installed in postcode 6150 (shared with Murdoch, Winthrop), from the Clean Energy Regulator.
That works out to about 73 systems for every 100 houses and townhouses in 6150, which is above the Perth average. Across Perth it's about 67 for every 100. 239 more were added between Oct 2025 and Sep 2026, so solar is still being installed here every week.
These count every small solar system registered since 2001, including upgrades and replacements, so they run a little higher than the share of homes with solar today. House counts are from the 2021 Census.
