South Australia’s leading renewable energy provider

Our history

Apex Energy Australia is Australian owned and operated from our head office located in South Australia. We are a design and construction company delivering solar and battery storage projects around Australia with a reputation for delivering client-focused solutions.

Paul Stallan, a long-time market leader in the commercial electrical and communications space, is the managing director of Apex Energy Australia, along with many talented project managers supporting all areas of our business.

Apex Energy Australia was established in 2009 and has quietly grown into a national supplier of solar and storage solutions in homes, light industrial areas and regional locations.

Apex Communication Technologies, the initial Stallan-owned enterprise, was established in 2004. Today we see the companies directly employ 60+ people in the South Australian office.
