Why we think this

Under threat because Business name pinnacle solar cancelled on 16 October 2025. Still trading signs: its website https://www.pinnaclesolar.com.au/ still loads; it had a SolarQuotes review on 7 October 2026; ABN 91660208926 (PINNACLE SOLAR PTY LTD) is still active. Only a business name has been cancelled. That can mean the business closed, or just that it now trades under another name or ABN. A second source (ABN cancelled, Google closed, dead website) would confirm a closure.

The date comes from: Last SolarQuotes review (last seen trading).

One sign of trouble (a cancelled name or ABN, a dead website, a run of one star reviews) but not enough to call it closed.
