The 1KOMMA5° Australia Story

Local Empowerment, Global Support

Having achieved the coveted unicorn status after just two years, 1KOMMA5° strategically focuses on acquiring interests in leading solar installation companies across Europe and Australia. Our approach involves investment and providing comprehensive digitalisation support and growth capital to these companies.

1KOMMA5° marked significant milestones with strategic investments in local Australian companies in Sydney, Melbourne, Brisbane and Adelaide.

While these companies continue to operate locally, they now benefit from the global support of 1KOMMA5°. This synergy allows us to bring cutting-edge technologies to the Australian market at competitive prices. Homeowners can now rely on the expertise of a robust local partner while efficiently managing their energy supply through renewable sources in a decentralised and sustainable manner.
