Why we think this

Under threat because Solar Directory archived its listing on 26 August 2026 because its website stopped working; https://www.formosaelectrics.com.au/contact does not answer (URLError). Still trading signs: Google still lists Formosa Electrics as open; ABN 94355160585 (KONING, JOSEPH WILLIM) is still active. Only its website has gone. Check Google, the phone number and the ABN before treating it as closed.

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.

The 50 most recent of its 96 SolarQuotes reviews

The 5 star reviews say

Reviewers praise the sales and quoting stage, with the owner Joseph visiting on site, running shade surveys and giving clear, honest quotes without pressure, and the install stage, with punctual, tidy crews who cleaned up and explained the system; some also mention post-install paperwork and grid connection being handled, and one notes the inverter issues were resolved well after install.
