Why we think this

Under threat because Business name ROOFTOP SOLAR AUSTRALIA cancelled on 19 March 2026; Solar Directory archived its listing on 17 August 2024 because its website stopped working. Still trading signs: ABN 40878323084 (The Trustee for nsp investment trust) is still active; ABN 84161139091 (CHAN KEE PTY LTD) is still active. One more independent source would confirm it as closed.

The date comes from: ASIC business names: Business name ROOFTOP SOLAR AUSTRALIA cancelled.

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.
