Australia's #1 Battery Installer for 2026
Recognised across 2 categories in the 2026 SunWiz Awards — for battery installations, residential solar volume across QLD, SA, NSW, VIC.
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. 1KOMMA5° is one of them, with 7 separate 2026 awards, every one earned 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.
1KOMMA5° is Australia's leading battery installer and a comprehensive "one-stop-shop" for renewable energy solutions, offering solar panels, battery storage, heat pumps, EV charging, and HVAC systems integrated with their proprietary Heartbeat AI optimization technology.
