Recent Projects
OSOS recently delivered Australia’s first prefabricated solar deployment at Norton Gold Fields’ Binduli operations in Kalgoorlie, West Australia.
The rapid installation of 2.3MWp of solar power, at a rate of 1MWp per week, sets a transformative benchmark for solar energy and is a testament to the vast potential for affordable solar solutions in the Australian mining industry and beyond.
In collaboration with Cambridge Energy and harnessing their cutting-edge NOMAD technology, these solar trackers feature a compact, prefab design and a unique earth anchoring system. Adaptable to any terrain, they prove invaluable in challenging or remote environments. Explore NOMAD solar trackers further on the Cambridge Energy website.
