Why we think this

Closed because SolarQuotes has been told it went out of business; Google lists Sunwise Energy (19 Ilmenite Cres, Capel WA 6271) as permanently closed. Closure dated 8 April 2026, from Last SolarQuotes review (last seen trading). Against that: its website http://sunwiseenergy.com.au/ still loads; ABN 33115585736 (2G's SMI 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.

What customers said

The 5 star reviews say

Reviewers praise the sales stage for responsive, knowledgeable staff who recommended suitable systems and quoted promptly, and the install stage for a tidy, efficient, professional crew who explained how the system worked and finished early or on time.
