AlphaESS is the second largest Battery Manufacturer For 2025

SunWiz is Australia’s primary source of market analytics for the Solar & Storage industry. We’ve been collating market information since 2009 and most of the leading solar businesses subscribe to our analytics. We collect information from many data partners that together encompass a large portion of the total installations that occur each month. No other market analyst has collated such a dataset. From this we are able to make a confident assessment of which are the top volume brands. We don’t have complete coverage and we’re willing to be proven wrong (in which case we’ll note it here and amend our ranks). The Australian Solar & Storage industry is world-leading, experienced, and competitive. Getting to the top of the leaderboard is therefore worth celebrating. It demonstrates a brand has got what it takes to be popular. And if a brand can remain on the leaderboard for multiple years, then that brand can rightfully claim to be the Best Solar Panel in Australia, Best Solar Inverter in Australia, or Best Energy Storage System (Battery) in Australia. SunWiz has been tracking every solar power system installed in Australia since 2009, including information on which solar equipment was used. We are the undisputed authority on solar market volumes, and our data is widely quoted by companies, NGOs, and government agencies. We’ve also been the undisputed authority on the Australian battery market since 2015. In 2025, SunWiz performed an in-depth verification and validation of battery manufacturers 2024 installation volumes, which we also cross-referenced against our own independent data sources. On this basis, we are also pleased to announce: 
  • AlphaESS is the 2nd-largest Volume Battery Manufacturer in Australia for 2025.
Sungrow is the #2 Battery Manufacturer in Australia.
