Why we think this

Under threat because WhySolar lists it as collapsed: External Administration (2020). National installer that struggled with rapid growth and warranty obligations. Still trading signs: Google still lists Clean NRG Solar | Solar Panels, Batteries and Inverters as open (90 reviews); its website https://cleannrg.com.au/?utm_source=GoogleMyBusiness&utm_medium=organic&utm_campaign=GMBWebsiteClicks still loads; it had a SolarQuotes review on 14 June 2026. One more independent source would confirm 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 275 SolarQuotes reviews

The 5 star reviews say

Five-star reviews praise clear, honest sales advice without pushy upselling, prompt quotes, a tidy and professional install, and friendly after-sales help such as free call-outs for inverter faults and follow-up on alarms. Most are written soon after the sale or install, with some noting good system performance.

The 1 star reviews say

The two 1-star reviews complain about poor communication and a deposit held for months after a quote, with the battery installation then abandoned, and about a customer sold a non-battery-compatible inverter that they say is now worthless and was not made right.
