Why we think this

Closed because LEESON SOLAR PTY LTD (ACN 153607937) is under external administration (administrators or liquidators appointed). Closure dated 24 January 2026, from Last SolarQuotes review (last seen trading). Against that: Google still lists Leeson Solar as open (40 reviews); its website https://www.leesongroup.com.au/ still loads; ABN 31153607937 (Leeson Solar Pty Ltd) is still active. Google and websites often lag a collapse, so the registers win.

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

The business has stopped trading: a register, Google or the industry's review sites say so.

5 SolarQuotes reviews

The 5 star reviews say

Reviewers praise the sales and quoting process, the OpenSolar design tool, the site visit by a design engineer before installation, install quality, competitive pricing, and after-sales support. Most of this praise comes from the sale and install stages, with one reviewer noting good support months after installation.

The 1 star reviews say

One reviewer objects to a solar farm being built in a flood zone and says Leeson did not reply to a request to meet about it, and that workers entered their property without permission. Another says Leeson did not turn up on an agreed install date, which forced extra scaffold hire, and describes poor communication. That reviewer also says their 8kW inverter on a 10kW array may be undersized, which they were told would be enough.
