What we found

Trading: it had a SolarQuotes review on 28 October 2026.

Open for business: Google, its own website or recent reviews show it trading. A cancelled old name or ABN beside a business that plainly trades on is a restructure, not a closure.

The 50 most recent of its 64 SolarQuotes reviews

The 5 star reviews say

Reviewers praise the sales process, with same-day or 24-hour quotes, honest advice, itemised written quotes, no deposit up front, and tidy, efficient, on-time installs that handled steep roofs. Some report the systems performed without problems after install, though one 2025 reviewer said the Goodwe follow-up service was poor.

The 1 star reviews say

The single 1-star review says a battery installation was never carried out, yet the company pursued an $8,500 claim through NCAT. The reviewer says the company later confirmed in writing that the work had not been done, withdrew the application, and said no further action would be taken.
