Questions

How is 'homes with solar but no battery' estimated?

Every solar system installed in the postcode since 2001, minus batteries installed since July 2025, never below zero and never above the number of homes in the 2021 Census. It is an estimate: the solar count includes replaced and upgraded systems, and batteries installed before July 2025 are only published by state, not by postcode.

What is the 3-month change?

Batteries installed in the last three complete months against the three months before, from Clean Energy Regulator data. The latest month is left out because it is still being counted.

What's in the CSV?

Every postcode in the state or region, ranked by estimated homes with solar but no battery, with the 3-month numbers and the typical battery size. Two columns hold each postcode in the forms Google Ads and Meta Ads take for bulk location targeting. It is free; you confirm your email first.
