Australia's #1 Manufacturer for 2026
Recognised in the 2026 SunWiz Awards as a #1 Fastest Growing ESS, based on verified data for the 2025 calendar year.
Choosing a solar installer you can trust is hard — the market is full of bold claims that are difficult to verify. SunWiz Awards exist to help Australian homeowners cut through that: they recognise the solar companies proven by independent installation and customer-review data — not marketing, nominations, or paid placement — to be among the best in their region. Fox ESS is one of them, recognised for #1 Fastest Growing ESS on verified data.
Since 2009, SunWiz has tracked every solar power system installed across Australia, documenting each company’s installation volume. Rankings draw on the Clean Energy Regulator REC-Registry plus verified records from STC service providers, and on audited customer review data for review-based awards. Ranking positions are determined by data, independent of whether a company chooses to participate — SunWiz Awards are determined exclusively by data rather than by judging panels, nominations, or sponsor relationships. As the recognised authority on Australian solar market volumes, SunWiz data is referenced by corporations, NGOs, and government bodies.
